BHS-Sonthofen supplies the largest indexing belt filter in the company“s history

Extraction of reusable substances from plant waste: New plant makes several process stages superfluous.

BHS-Sonthofen supplies the largest indexing belt filter in the company"s history

The BHS indexing belt filter during final assembly at the beginning of 2016 at the Sonthofen plant.

BHS-Sonthofen has received the order from an American customer to supply an indexing belt filter for extracting reusable substances from plant waste. With a filter area of almost 90 m², the type BF 350-255 filter plant is not only the largest plant that BHS has ever built, but it is also one of the most efficient of its kind in the world.

The indexing belt filter of type BF 350-255 will process up to 5,000 kg of fibrous plant waste hourly, extracting recoverable liquid components generated in a previous production process. The filtrate is used for the manufacture of basic chemicals, while the remaining solids, which could not previously be used, are reprocessed.

During project planning, the customer had initially envisaged a multi-stage process with a sequence of consecutive screening and filtration steps and with the solids being resuspended several times. The proposal from BHS-Sonthofen to use an indexing belt filter of type BF with a single process step convinced the customer, however. Not only is the process much simpler, but it also concentrates the reusable substances to a greater extent. This means that less energy is required for extracting the substances at a later stage in the process.

As part of the treatment process, the plant waste is first suspended in water. To ensure that the reusable substances dissolved in this can be extracted as effectively from the solid as possible, BHS implements a multistage counter-current wash process in the filter plant. This allows the filter to achieve a very good washout quality, thereby significantly increasing the concentration of the dissolved reusable product in the liquid. The BHS indexing belt filter of type BF 350-255 extracts approximately 10 percent more recoverable materials than conventional procedures.

Moreover, the operating costs are lower because the indexing belt filter requires about 30 percent less water than the multistage process. This also results in considerably lower investment costs as no multiple cascades of stirring tanks and filters are required. As the entire filter plant is much simpler in design than conventional plants, it ensures a high operational reliability. At the same time, maintenance costs are significantly lower in comparison to conventional plants.

After receiving the order in December 2015, BHS supplied the filter plant in spring 2016. Commissioning is planned for autumn 2016.

Background: The BHS indexing belt filter of type BF

The indexing belt filter is a continuously operating, horizontal vacuum filter that allows for reliable and gentle separation of sedimentation solids from suspensions. The filter medium is a circulating belt, which moves forward in cycles.

Each time the cloth stops, the filtrate is sucked downwards. Then the vacuum is switched off to release the filter cloth, which can now be moved forward. The filter cake forms on top of the belt and can undergo further treatment by washing (co-current or counter-current), reslurrying, steaming, extraction, vacuum drying or pressing. During this process, the filtrates can be recovered individually from each vacuum tray and further processed without any cross-contamination. The filter cake is discharged at the discharge roller. The cloth is cleaned as the belt returns.

The design of the BHS indexing belt filter allows continuous, even feeding of the suspension via distribution devices, which also spread the solids gently. The filter cake formed by gravity and vacuum is not subject to any mechanical forces during transportation or further treatment. This makes the indexing belt filter suitable for pressure-sensitive solids as these can be processed without grain particle breakage.

IFAT debut: New Universal Shredder – completely redesigned

Recycling and crushing technology

IFAT debut: New Universal Shredder - completely redesigned

The new Universal Shredder of type NGU 0513: The screen basket (purple) can be lowered downwards.

BHS-Sonthofen will unveil the new Universal Shredder of type NGU at IFAT 2016. This new product extends the company“s range of single-shaft shredders by a machine designed for conventional recycling facilities and use in the manufacturing industry. It is generally suitable for all materials that can be cut and is characterized by a sturdy design, easy operation and high availability. The new Universal Shredder is available in several versions – for example with a screen perforation of 30 mm – for a throughput of 6.5 t/h and more.

The new Universal Shredder of type NGU shreds the loaded material to a size between 20 and 100 mm. It can be used at conventional recyclers for shredding various materials, for example, for cutting paper and paper rolls, for destroying files and data media, as well as for almost all plastic parts, leather and textiles, residual wood, cables or parts made from PET.

It is also suitable for production companies that generate large volumes of waste. In this field of application, it size reduces the material so it can be processed further at the same facility or to facilitate transportation to the treatment company. A typical application involves plastic barrels, which are collected centrally at one location in a company and then shred in order to reduce the transport costs for further processing.

Dennis Kemmann, Managing Director of BHS-Sonthofen GmbH, has completely redesigned the machine with his team: „Our aim is for our customers to achieve the lowest possible processing costs per ton. Before getting down to the design, we asked many users what their main shredding requirements were. Their answers and the long-standing experience of our engineers were incorporated into the design. The result: A completely newly developed machine that economically shreds everything you can possibly cut.“

BHS added many technology advances insuring excellent machine uptime. This begins with the sturdy design and long service life of the individual components and extends from the simple removal of contaminants through to short maintenance times and the rapid availability of spare parts.

The technology:

The loose feed material is loaded into the feed hopper, which BHS-Sonthofen individually adapts to the material and type of feeding.

A hydraulically driven slide pushes the material along the base plate and toward the cutting system where granulation takes place. The rotor is equipped with replaceable blades, and the stator has an adjustable counter-blade with a material specific profile. BHS configures the style, quality and number of blades to the specific application at hand.

Once the cut material reaches a defined partical size, it falls through a screen basket downwards and out of the machine. The size of the discharge material is defined by the hole size of the screen, it can be between 20 and 100 mm. The screens are individually replaceable and can be rotated at 180°, increasing their service life considerably. The screen basket can be lowered downwards. In this way, BHS avoids the need for overhead work when inspecting the machine or replacing the screen.

As contaminants can never be fully prevented from falling into the feed material, the base plate is mobile and can be lowered from the cutting gap, if required. This allows for fast removal of contaminants. The screen basket can also be folded away for inspections.

The throughput depends to a large extent on the density and toughness of the material as well as the method of feeding. Interested parties can request that the company perform tests in their technology center at the Sonthofen plant, to determine the ideal machine configuration. This gives customers the certainty that their material will be processed efficiently.

BHS-Sonthofen supplies the machine in two versions: The Universal Shredder of type NGU 0513 with a rotor length of 1300 mm for a throughput of up to 5 t/h as well as type NGU 0518 with a 1800 mm rotor for up to 6.5 t/h – each based on a hole diameter of 30 mm. The motor drives are available up to 132 kW.

The drives are frequency controlled, and the speed of the rotor is adjustable between 80 and 240 rpm. As a result, the machine can be configured to account for the properties of different feed materials. For easy to shred materials, for instance foils, high speeds are preferable in order to attain a high throughput. Solid semi-finished plastic products, full plastics as well as thick or heat-sensitive materials are shred at lower speeds.

The blades of the rotor shaft can be utilized on both sides and are rotated with minimum manual effort. The counter-blade can be adjusted. This ensures that the cutting gap is always optimally calibrated. It can also be used on two sides and replaced within the shortest time.

The design engineers have also attached considerable importance to high availability in the context of adapting the machine to various requirements: The screen basket can be changed within a few minutes. This is advantageous when destroying files, for example, if different protection classes are applicable in successive batches.

Recycling machines from BHS-Sonthofen:

When taking over AMNI Maschinenbau GmbH in 2013, BHS-Sonthofen extended its product portfolio of recycling machines by adding shredders and granulators with cutting technology. Today, the company offers a wide range of shredders, granulators and crushers with impact and shear crushing alongside cutting technology.

At IFAT, BHS will present a further single-shaft crusher for the first time: The new „SpeedCut Granulator“ of type NGV with a throughput of up to 15 t/h is designed for the granulation of domestic refuse or industrial waste for refuse-derived fuels.

BHS-Sonthofen will also continue manufacturing the proven „HeavyCut Granulator“ of type NGH with swiveling stator for heavy feed material such as tires, electrical and electronics scrap or aluminum composites.

Major contract from Switzerland: Non-ferrous metals in incinerator bottom ash are turned into valuable resources

Processing and refinement of metals derived from waste incineration plant slag and other metal-bearing materials

Major contract from Switzerland: Non-ferrous metals in incinerator bottom ash are turned into valuable resources

The head office of DHZ in the Swiss municipality of Lufingen was built using sustainable materials.

BHS-Sonthofen was commissioned by Swiss-based DHZ AG to build a complete plant for processing concentrated metals bound in incinerator bottom ash. The plant will also be able to process and refine a wide range of metal-bearing materials. Recycling machines from BHS are core components of both processing lines, as they allow for efficient and selective shredding. This order from Switzerland is the largest ever for the Recycling Technology division.

The Swiss company DHZ AG, which is based in Lufingen near Zurich, operates a modern landfill and connected recycling plant. This plant is used to sort out resources and contaminants from the materials to be put into the landfill; rather than being deposited, these are then further processed. The supersort® facility for processing ash from waste incineration plants with a capacity of more than 100,000 tons of ash per year takes up a major portion of the recycling plant.

In order to further process the highly concentrated metals delivered by the supersort® facility, DHZ is setting up a new processing plant called supersort®metall in the neighboring town of Oberglatt. The annex will process non-ferrous metal concentrates originating from customer facilities and the supersort® and supersort®fein plants of DHZ. In addition, metalliferous fine fractions derived from shredding vehicle scrap and electronics devices will be further processed there. Lead from backstops can be processed as well. The goal is to attain high-quality heavy and light non-ferrous fractions from the concentrate that are to be sold to smelting works or industrial customers. Each line of the plant has a processing capacity of 10 tons/h.

DHZ specifically required a provider able to offer a dry processing method because wet processing would have incurred significant additional costs due to the high requirements associated with water and sludge treatment.

This was one of the reasons why the customer chose selective granulation technologies from BHS-Sonthofen as the central components for their new facility. Machine technology for the recycling industry is based on the method of impact crushing using impact mills.

BHS-Sonthofen has been commissioned with delivering the machine technology as well as with implementing the entire new plant to full operability in 2016. The delivery scope comprises two entire lines – one for generating particle sizes from 8 to 100 mm and another for fine processing in the range of 0 to 10 mm. BHS will deliver all components, from feeding systems through to big bag loading stations. The list of components includes various BHS impact mills, sifting machines, zigzag sifters, cyclone separators, magnetic drum-type separators, separating tables, the entire conveyor system, a dust removal system, steel construction works as well as controlling and visualization.

Machines from BHS-Sonthofen include an impact mill of type PM 0806, one rotor impact mill of type RPMV 1113 and one rotor impact mill of type RPMX 1516. These machines process granulates from 8 to 100 mm and produce a fine output with sizes from 0 to 10 mm. As a final step, the processed material is cleanly separated by type – for example, according to light and heavy non-ferrous metals, ferromagnetic materials, oversized particles and dust – and then filled into big bags.

For Alfred Weber, Sales Director Recycling Technology at BHS-Sonthofen, this contract underscores the success of BHS“s strategy to offer a continuously increasing range of complete plants: „Our client greatly appreciates that we do not simply deliver individual machines, but rather provide a fully operable plant in turn-key condition.“ Incidentally, the DHZ order is the largest the Recycling Technology division has ever received since its founding in 2001.

Construction commenced in early 2016, and the plant is scheduled to go live in the summer of the same year.

Background

BHS Impact Mills

The BHS machine technology portfolio for the recycling sector comprises various horizontal- and vertical-shaft impact mills. All of them are based on the impact crushing principle. Recycling machines are selected according to the respective feed material and the required final quality.

In the case of the BHS impact mill of type PM with a horizontal shaft, the feed material is inserted into the crushing chamber via an inlet shaft; there, the material is impacted by a high-speed rotor, which accelerates it against the impact walls. The material is pre-crushed in the upper section of the crushing chamber, while the lower section is where the required final particle size is attained.

The BHS rotor impact mills of types RPMV and RPMX are high-performance impact crushers with a vertical shaft. The feed material is loaded into the machine from above at the center. When it impacts the rotor, the material is accelerated towards the outside by means of centrifugal forces; there, the horseshoe-shaped hammers engage it and throw it against the anvil ring, where it is crushed as a result of the impact and shearing forces. Once the material has been sufficiently reduced in size, it exits the crushing space through the ring gap and falls down through two outlet chutes.

BHS-Sonthofen: Saving gold from landfills!

BHS-Sonthofen: Saving gold from landfills!

The rotor impact mill of type RPMV is a high-performance, vertical-shaft crusher

Recovery of metals from fine shredder fractions: The BHS rotor impact mill is the centerpiece of the complete solution for recycling.

When automobile scrap and electronic equipment are shredded, the fine fractions of the crushed material still contain considerable amounts of precious metals which until now have invariably been deposited in landfills. Treatment plants from BHS-Sonthofen use a one-of-a-kind process to reclaim these metals, allowing them to be sold profitably.

Approximately 20 grams of gold, 200 to 300 grams of silver, as well as platinum and other precious and non-ferrous metals: this multitude of resources can be hiding in one tonne of heavy non-ferrous fraction. In the recycling process for automobile, electrical and electronic waste, the coarse components are shredded and treated, leaving this fraction behind.

Despite its great value, this fine material is usually disposed of at landfills or incinerated. As more and more electronic components and boards are used in vehicles and electronic devices, all the more valuable resources are lost.

With its complete solution for the fine treatment of shredder residues, BHS picks up where others have left off: substances once headed to the landfill or incinerator are now fed back into the material cycle and profitably recycled. Operators report that the sale of the materials, for example the heavy fraction of non-ferrous metals, brings them approximately 3,500 euro per tonne, and that their plants have paid for themselves within nine to twelve months. However, the plant does not just generate income from the sale of metals; it avoids landfill costs as well. In turn, this serves to unburden landfills, which is all the more significant in light of the new landfill directive. When compared to other systems, rotor impact mills for recycling applications (type RPMV) also feature low wear-related costs, contributing in large part to low costs of operation.

Shredding used to be of commercial interest mainly for ferromagnetic materials. In the 90s, the recycling of non-ferrous metals also became economically viable. Today, with modern plant technology, the sale of precious metals is lucrative as well. BHS pioneered this development with a one-of-a-kind machine: the rotor impact mill (RPMV), manufactured by BHS alone worldwide, set the stage for the clean separation of non-ferrous metals from other materials.

Building on its scrap crushing expertise and with many of its rotor impact mills integrated in similar processes, BHS has developed a complete solution for fine-grain treatment. It combines impact crushing technology with physical separation methods and comprises all process stages from the feeding of material to the separation of individual substances to the removal of dust.

In the first part of the process, the input material is crushed and the lightweight materials are separated. In the second stage, the remaining material is screened and sorted by density. The final products are thus various materials and metal fractions cleanly separated according to type and grain size.

The centerpiece of the plant is the rotor impact mill of type RPMV. It crushes the brittle-hard materials and shapes the ductile, metallic ones into balls. The standard plant, which BHS offers as a complete solution, achieves a throughput of approximately 10 tonnes per hour. On request, BHS designs larger plants tailored to specific customer requirements.

The rotor impact mill crushes and disaggregates the material (grain sizes between 0 and 20 mm). The machine works selectively here: brittle materials – for example mineral substances, glass or castings – are finely crushed and the composites are separated, while elastic materials such as rubber remain intact.

The key effect of the sorting is that ductile metals, i.e. those which can be deformed plastically, are shaped into balls in the rotor impact mill. This is why the machine is also referred to as the „ball shaper“. It lays the foundations for the next stage, which cleanly separates the non-ferrous metals from the other materials. In order to be separated and conveyed to the downstream process stages, the non-ferrous metal parts, which are often long and flat, should have as compact and spherical a form as possible.

The result: cleanly separated materials

At the end of the process, all of the fractions are cleanly separated in bins. In addition to proportions of the precious metals mentioned above – gold, silver and platinum – the fraction of non-ferrous metals contains considerable amounts of aluminum, copper and brass, which can also be sold. Depending on the composition of the waste material, the BHS fine treatment plant recovers between five and seven percent of this input as saleable non-ferrous metal.

A positive cost factor is that the whole process is to a large extent automatic and the entire plant can be controlled and monitored by just one employee. An additional employee spends about half of his working hours on the material logistics.

AMNI shredding machines for recycling applications

AMNI shredding machines for recycling applications

Managing Director Dennis Kemmann (right) together with Udo Becker

Treatment of all kinds of materials: Shredding technology rounds off BHS-Sonthofen“s product range

BHS-Sonthofen has acquired all technical designs and documents, patent rights and trademark of the recycling technology division of AMNI Maschinenbau GmbH in Iserlohn (Germany) following its insolvency, effective from December 12, 2013. This has allowed BHS – a company known to date in the recycling sector for crushing by means of impact and shearing technology – to expand its product range into shredding technology using cutting tools. BHS thus now covers the full range of crushing and shredding technology for both brittle and elastic materials. At IFAT 2014, the company will unveil the rotor shears and granulators acquired from AMNI and upgraded by BHS.

AMNI manufactured rotor shears and granulators of various sizes for numerous customers for the treatment of electronic waste, tires, cables, refuse-derived fuels and other materials. They are robust and easy to maintain, and have a number of patented features as well.

For BHS-Sonthofen, this attractive acquisition rounds off its existing product range, as the company from Sonthofen has until now offered recycling machines exclusively based on impact and shearing technology. These machines crush the bulky input material and also achieve a selective disaggregation of composite materials. With rotor shears and granulators, BHS now also manufactures machines which are suitable for recycling elastic materials. These include domestic, industrial and commercial waste, cables, and car and truck tires – extending even to tires for construction machinery with a diameter of up to 3 m. The machines are also able to handle paper and cardboard, for example books or files, as well as wood and textile waste.

Since December 2013, Udo Becker, head of the former recycling technology division of AMNI, has been in charge of the further development and manufacture of the BHS shredding machines as Business Development Manager in Sonthofen. He is responsible for ensuring continuous support for operators of rotor shears and granulators. The maintenance and repair of existing plants and the supply of spare parts to former AMNI customers will be carried out by the BHS service team from now on.

Dennis Kemmann, Managing Director of BHS-Sonthofen, sees an important addition to the company“s range with this new product segment: „We can now offer all commercially available crushing and shredding processes in the field of recycling with our own machines. Each technology has specific advantages depending on the application. This is the ideal solution for many input materials, for example for mixtures of different materials. For the selective crushing of brittle-hard materials, we will continue to implement impact and shearing technology, and the rotor shears and granulators will shred the predominantly elastic materials. The advantage for our customers is clear: regardless of the material to be recycled, we offer the optimal solution from a single source.“

The proven VR rotor shears – now upgraded by BHS – are mostly used for pre-shredding at the beginning of each recycling process. They are equipped with two shear shafts which rotate at approx. 18 rpm. The machines are designed for a throughput rate of between 6 and 30 tons per hour.

The NG series granulators are used for granulating and separating composite materials as well as for the secondary shredding of difficult or large-volume materials – for example electronic waste and non-debeaded tires. Compared to the rotor shears, the shear shaft rotates significantly faster, at up to 420 rpm. With their high-torque drive and large inertia masses, the granulators develop very high shredding forces.

The technology in detail

Rotor shears
In addition to a good cutting performance, high availability was at the fore in the development of the machines: the housings consist of a one-piece, extremely robust and warp-resistant welded steel construction. The cutters are hard faced, allowing them to achieve a remarkably long service life. The scrapers can be replaced individually.

The two industrial gear units, which drive the rotor shafts in opposite directions, are torque-buffered. This relieves the load on the shear shafts and drive components if solid extraneous materials enter the machine. In case of overload, a current-based reversing control system protects the machine from damage.

The quick-change system for the shear shafts also contributes to short standstill times. Owing to the bearing shell bridging system, the shafts of the rotor shears can be exchanged within just four hours. This task now takes less than 20 percent of the time previously required.

The control system has a modem for remote maintenance. It can also be equipped with an electronic consumption optimizer, which balances the power, torque and current requirements. In this way, only the power that is actually required at any given time is developed – energy costs decrease and the plant functions much more economically.

Granulators
The granulators shred pre-crushed or pre-treated input materials. The NG series machines are single-shaft granulators in which a rotor equipped with fly cutters shreds the materials on the counter-blades of the stator. The rotor is equipped with a belt flywheel and can be controlled within a speed range from 0 to 420 rpm.

Special design features ensure excellent cost-effectiveness and durability. These include the extremely robust, external rotor bearings, the modular stator with blade segments which can be individually adjusted, and wear compensation with linear advance of the stator blades. In addition, the hydraulically retractable sieve can be exchanged simply without the need to dismantle the discharge equipment.
