Product Portfolio
  • Industrial Shredders

      • LR520

      • Compact and reliable shredding of small residual timber volumes

        We designed the LR520 based on the requirements of small companies. This wood shredder is therefore especially compact, reliable and very energy-efficient. The simple and thus low maintenance technology and the extremely small footprint (<1 m²) enable you to efficiently recycle your residual timber. The LR520 is best suited for companies that have a residual timber volume of up to 3 m³ per week.

        The wood shredder's reliability comes from its sturdy steel construction and its proven technology. The pusher-free design has a pull-in mechanism and therefore very few moving parts. This reduces maintenance costs to a minimum. The gear damper cushions strong blows during the shredding process and ensures the machine's quiet operation. In addition, the LR520 features a mechanism that detects foreign objects and automatically shuts down the shredder. This prevents damage to the cutting unit.

        Energy efficiency plays a big role in the LR520. The proven cutting system can easily shred residual timber and only requires a drive capacity of 11 kW. When it idles for more than 3 minutes, the machine shuts down automatically. This saves energy and simultaneously reduces operating costs.
         

        The LR520 produces high-quality granulate that is well suited for thermal utilisation or briquetting. Each of our wood shredders is customized to your needs. The machines can also be equipped with a metal separator, a conveyor system or a customized hopper. We offer comprehensive solutions from one source!

      • High reliability for many years to come
         

        The reliable and very sturdy RS30 and RS40 shredders have been tested and proven over several decades and are used particularly for processing long solid timber pieces. The wood chippers can be operated as stand-alone solutions or integrated into complex systems where they tend to be a favourite thanks to their very compact design. They are characterized by their high availability and unique productivity.

        The high reliability of this series is a result of the machine's rugged cast-iron frame design and the sturdy cutting unit. The low-speed, 4-shaft shredders are not sensitive to foreign objects and are very low maintenance. Thanks to the pull-in mechanism the shredder does not need a hydraulic pusher system, which further reduces the need for maintenance. The low speed of the cutting shafts ensures low noise and dust emissions in your operations.

        The machines are particularly productive thanks to the high torque in combination with a large perforated screen surface and are a favourite for multi-shift operations. In the event that foreign objects are pulled in, the shredder automatically shuts down thereby preventing greater damage to the cutting unit. The shredder is additionally equipped with an automatic reverse to prevent motor overload.

      • Industrial shredders for difficult recycling applications
         

        This industrial shredder has been tried and tested under difficult conditions is characterized by very high reliability, ability to handle non-shreddable extraneous materials as well as a very broad application range. Its sturdy design and the strong, resistant cutting unit is particularly well suited for continuous multi-shift operations.

        The medium-sized RS-class shines especially in difficult recycling applications. Thanks to the modular design and the various cutting unit configurations these shredding machines are particularly flexible in their use. Moreover, it is possible to adjust speed, torque, sealings, cutting unit openings and perforated screens exactly to your requirements. This ensures highest flexibility with maximum reliability.

        In contrast to high-speed systems, these slow-speed industrial shredders are particularly resistant to foreign objects. If a cutting disc detects a foreign object, the machine stops immediately. This prevents damage to the cutting unit. In addition, the drive permits frequent reversing, which is particularly beneficial when shredding problematic materials. The integrated perforated screen quick replacement system that comes standard permits the quick and efficient replacement of the perforated screen.

        The shredding machines can also be equipped with additional separating and conveyor technology, customized hoppers and substructures and control expansions. We offer comprehensive solutions from one source!

      • RS150

      • The smart power package for exceptional requirements
         

        The RS150 is the largest UNTHA heavy duty four-shaft shredder and has been developed for especially difficult applications where a high throughput performance, high availability and low maintenance cost are all required.

        The highlight of this unique innovation is the newly designed UNTHA Eco Drive. The dynamic and energy-efficient drive concept ensures that the cutting inserts are stopped immediately if foreign objects are pushed in so as to prevent the cutting tools from being damaged. Moreover, this drive permits frequent reversal which is particularly necessary when shredding difficult materials.

        The throughput performance can always be optimally configured for the material to be shredded with the variable speed setting option for the cutting shafts. In contrast to high-speed systems (asynchronous motors), these machines do not require wearing parts such as couplings, belts or shear pins, which reduces the machine's vulnerability.

        The large RS series can also be equipped with additional separating and conveyor technology, customized hoppers and substructures and control expansions. We offer comprehensive solutions from one source!

      • XR2000/3000

      • Flexible waste shredder for all kinds of waste streams
         

        The XR class is a high-performance solid waste shredder for the size reduction of different waste streams like C&I waste, MSW, bulky waste, pulper ropes, rolled goods, carpets or wood waste. The slow speed shredder is often used as a pre-shredder / primary shredder in a comprehensive system or simply as a single-pass shredding concept to produce alternative fuels. The robust design enables even untreated material containing unshreddable items to be processed in one pass. These items can be removed quickly and easily using the impurity removal system, which keeps downtime to a minimum.

        Customized slow speed shredding solutions: MSW shredder, C&I shredder or waste shredder for different material

        To fulfill your individual requirements, the XR class is available with a ripper, cutter or X-cutter system. The combination with our patented XR screen bars or different-size screen systems makes a fraction size from 400 to 30 mm possible. The final throughput will depend on the type of material and the screen diameter and ranges from 10 t/h to 70 t/h.

        The high torque and the machine’s perfectly aligned cutting system enable the material to be fed directly into the machine without pre-shredding. A load-dependent speed control ensures a constant throughput rate.

        Throughput rates you can expect by single-pass processing of different materials:

        • Commercial and industrial (C&I) waste: 25 t/h < 80 mm
        • Municipal solid waste (MSW): 70 t/h < 300 mm
        • Bulky waste: 30 t/h < 300 mm
        • Waste wood: 45 t/h < 100 mm

        Low operating costs

        Minimal operating costs paired with maximum performance make this waste shredder a strong partner that stands out for its forward-thinking technology, such as the UNTHA Eco Drive concept that lowers energy consumption by 75% compared to standard electro-hydraulic drive options.

        State-of-the-art synchronous motors achieve maximum efficiency, making the UNTHA Eco Drive one of the most energy-efficient drive systems on the market. In addition, maintenance costs may be reduced to a minimum as the unit is free from pulleys, hydraulic pumps and shaft stubs. Where higher throughputs – and therefore also higher rotor speeds – are required, there is the option of integrating a safety coupling that will separate the rotor from the drive if a foreign object is detected.

        All rotors are wear-protected thanks to welded Hardox plates, making them particularly resistant against abrasive materials. Our experienced project engineers are at your disposal to assist with the planning and implementation of your project.

          • Refuse Derived Fuels (RDF)

          • Our alternative fuels shredders enable you to optimally recycle waste into substitute fuels and ensure high quality by producing a homogeneous granulate free of foreign objects.

            Co-processing of industrial waste in cement kiln

            The goal of recycling is to use the valuable energy contained in the waste and to substitute the use of fossil fuels. During the recycling process the portions with a high calorific value are separated from the commercial and industrial waste and turned into a marketable product. Depending on the calorific value and the granular size, these fuels are used in fluidised bed combustion, cement plants and substitute fuel power plants.

            The waste undergoes a single-phase or multi-phase recycling process to separate the fractions with a high calorific value from household waste, bulky waste, industrial waste, commercial waste and sorting residue. This process may consist of the following steps:

            Single-phase recycling process:

            • Shredding
            • Separation of ferrous and non-ferrous materials

            Two-phase recycling process:

            • Pre-shredding
            • Sifting process
            • Air separation
            • Separation of ferrous and non-ferrous materials
            • Ballistic separation
            • Separation of heavy materials
            • Optical sorting
            • Re-shredding

            We are world leaders in this complex field of substitute fuel recycling. Regardless of whether you require single-phase or multi-phase shredding, we offer an economic and, first and foremost, reliable solution!

            Utilization areas and fraction sizes of substitute fuels

            • Pre-shredded waste < 400 mm: The shredded material is particularly suitable for material recovery facilities (MRF)
               
            • Pre-shredded waste < 150 mm: This fraction size is suitable for co-generation power plants with grate firing, refuse combustion plants, material recovery facilities (MRF) and mechanical biological treatment. The untreated residential waste reaches an approximate calorific value of approximately 9-11 MJ/kg
               
            • Substitute fuel < 80 mm: for co-incineration use in cement plant calciners, fluidised bed combustion and power plants for energy recovery. The resulting calorific value of this fraction is approximately 15-18 MJ/kg
               
            • Substitute fuel < 30 mm (SRF): Ideally suited for the injection furnace in cement plants and substitute fuel power plants. The secondary fuels in the mixture for the co-incineration in cement rotary kilns must have a calorific value of at least 18-22 MJ/kg
          • Waste processing

          • Our industrial waste shredders are well suited for 1-step or 2-step waste recycling and shred the material down to a fraction size of 400 to 30 mm. We offer powerful and versatile waste shredders for the volume reduction of different waste streams such as C&I waste, municipal solid waste (MSW), commingled waste, bulky waste and waste wood. The XR waste shredder can be individually tailored to the needs of waste disposal and recycling companies that require single-pass processing of household, industrial and commercial waste into alternative fuels (RDF/SRF).

            A mechanical-biological waste recycling is usually performed when processing household or commercial waste similar to household waste. The goal of this treatment is to generate a landfill-suited waste material by separating waste fractions with a high calorific value, valuable resources as well as foreign objects.

            We understand the tough requirements that the shredding technology of a mechanical-biological waste recycling system faces. With our newly engineered waste shredder we are able to offer the ideal product that meets these tough requirements for both low operating costs and high availability.

            Overview of the different technologies for mechanical-biological waste processing

            • Mechanical-biological waste treatment: In this process, the waste is mechanically separated from the metals and the fractions with high calorific value are sifted out. The subsequent biological treatment occurs in the form of a decomposition or fermentation process. The end product can be deposited in a landfill due to its low biological activity.
               
            • Mechanical-biological stabilisation: The mechanical-biological stabilisation is different from the mechanical-biological waste treatment because in addition to the biological treatment, the fractions with a high calorific value are recycled into substitute fuels.
               
            • Mechanical-physical stabilisation: This process generates substitute fuel through a mechanical and physical sorting process (e.g.: separation of materials containing iron from materials not containing iron) using a multi-phase recycling process. The substitute fuel is usually processed into pellets or fluff. 
          • File, data and material destruction

          • Our hard drive shredders and industrial paper shredders reliably protect your sensitive and confidential data from the prying eyes of third parties. We guarantee a secure and uncompromised destruction of your data pursuant to the most recent DIN 66399 standard.

            We offer customized shredding solutions depending on the required protection class, security level and type of data to be processed. Our robust hard drive shredders and industrial paper shredders have been tested and proven over several decades and excel where other traditional shredding systems cannot. 

            The independent certification centre DEKRA confirmed in an expert report that our 4-shaft shredding machines easily meet the new security standard DIN 66399-2 (destruction systems for files and data carriers).

          • Waste wood recycling

          • Waste wood is a precious resource that is available in large volumes and may be used either for material recycling or energy production, depending on the quality grade. The rising cost of waste material disposal and a growing consciousness for the environment also contribute to the increasing importance of waste wood recycling. The term “waste wood” includes all woods and wood-based materials that have come to the end of their product lifespan and are thus considered waste.

            We offer you innovative, highly economical single-step shredding concepts for the recovery of your waste wood, upon request also with metal separation. Units are available as stationary or mobile versions. Low operating costs, extremely low fines and foreign object protection paired with high performance are the key factors in the success of UNTHA waste wood shredders. Minimised dust and noise levels benefit your employees, your neighbours – and ultimately also the environment!

            Processed for thermal utilisation or recycling

            During the recovery process, the waste wood is shredded and separated from foreign matter such as metal parts. The resulting wood chips are either recycled or utilised for energy production, depending on their classification grade. Recycled waste wood is often used as raw material for the production of chipboard or other wood-based materials. In case of thermal utilisation, the wood chips are used as high-grade fuel in biomass or thermal power stations.

            We offer reliable shredders with a throughput of up to 40 t/h for waste wood recovery. Our units are suitable for a wide range of applications.  

          • Plastic materials

          • As a renowned manufacturer of reliable plastic shredders, we offer special machines for in-house recycling and for heavily contaminated post-consumer waste.

            Due to its format, components and characteristics, plastic is a very versatile material that is primarily used in industrial mass production. The resulting plastic waste can be recycled by shredding and washing the material, before generating a reusable, recycled granulate. Shredded plastic waste can also be used for energy generation.

            Our plastic shredders were developed specifically for the processing of these components. They deal effortlessly with all kinds of plastics, ranging from foils, lumps, profiles, fibres, ribbons, PET bottles and hollow parts to post-consumer and production waste. Thanks to a range of different cutting systems, rotor diameters and shapes as well as different blade sizes, the shredders are suitable for thermoplastics, duroplastics and elastomers and may be customised to suit your individual requirements.

            Impressive references

            Take a look at our current reference book "Plastics" and get an impression of how companies around the world use our shredders successfully:

          • Metals

          • Regardless of whether your metal waste comes from the metal-processing industry, automotive industry, electronics industry, waste industry or commercial production, we will always offer you the right shredding system for recycling your valuable resources!

            Metals are important raw materials for the industry and can be repeatedly returned to the recovered resource cycle with very little loss. The recycling of metals saves valuable raw materials and energy as opposed to the new processing of ores.   

            Our sturdy industrial metal shredders have been tried and tested a thousand times over, reliably and efficiently shred light metals such as aluminium, magnesium, Al-Mg alloys, copper or nickel, as well as harder metals such as iron, zirconium, titanium and sheet steel.

          • Electronic scrap

          • Our customized e-scrap shredders enable you to process electronic scrap in your recycling facility and they align perfectly with your recycling system. The granulate size is adjusted in such a fashion that metals and non-metals can be separated and recycled as completely as possible.

            More than 40 million tons of electrical and electronic scrap are generated annually – and the trend is growing dramatically! Recycling electronic devices is not just beneficial for environmental reasons. This scrap, as a rule, contains many precious metals that are recovered during the recycling process. To ensure a high yield during the recovery process, the shredding step should generate only a very low amount of fine particles.

            E-scrap shredders that meet your needs
            Our reliable 4-shaft shredders are particularly suited for processing e-waste. Their low speed ensures that printed circuit boards and old devices are carefully shredded with low emissions. The recycled material is ideally suited for e-scrap recycling machines and subsequently for cutting facilities where precious metals are separated from impurities.

          • Paper and cardboard

          • We offer customized solutions for shredding paper and cardboard. Our experienced technicians optimally configure the shredding system to meet your needs and thus ensure a perfect shredding result.

            Paper, cardboard and pasteboard are valuable raw materials that play an important role in recycling and in the waste processing industry. The easy recyclability of cellulose permits the economically efficient and environmentally friendly reuse of paper. Before shredding, the material is sorted based on its prior use, foreign objects are removed and only then is the material shredded.

          • Hospital waste

          • Our hazardous waste shredders are perfectly suited for the chemically aggressive material in your hospital waste. After the shredding process, the material can be optimally utilised thermally or disposed of together with municipal solid waste once it has been sterilised. The shredding is so effective that the granulate does not give any indications of the source material.

            Hospital waste consists of very different types of waste and requires special treatment during disposal due to the presence of infectious and highly contaminated materials. Depending on the waste type or classification, the hospital itself might need to specially treat the waste or store it in dedicated plastic containers or drums on-site.

            Our hazardous waste shredders have been tested and proven multiple times for shredding medical waste or tough materials like oil filters. Our customers particularly value the high operating reliability, low emissions and easy maintenance. The shredded material can, thanks to subsequent sterilisation, be used either as a substitute fuel or disposed of together with municipal solid waste.

            When it comes to hazardous waste shredding you can profit from our experience. More than 100 customers trust in our hazardous waste shredders worldwide.

          • Organic waste

          • Our shredding solutions process biological and biogenic waste to generate an optimal substrate for further utilisation in your biogas plant or in your disposal business. The application area ranges from green or garden waste to food waste and expired goods including packaging to slaughterhouse waste.

            Non-homogeneous or organic waste in pieces including packaging must be shredded to prepare it optimally for fermentation. Our low-speed organic waste shredding solutions are ideally suited for this application. These two-shaft shredders ensure reliable processing and guarantee a pumpable fermentation substrate. Thanks to the special equipment, efficient cutting unit and sturdy machine construction, these shredders are very reliable and have a long service life!

          • Pulper ropes

          • In addition to a homogenised granulate of your residual products, our customized shredding systems guarantee an optimal pre-product for further recycling or thermal utilisation in your plants.

            Our customised shredding systems not only turn your waste materials into a homogeneous granulate, but also provide an ideal pre-product for further processing and/or thermal recovery within your plant.

            Pulper ropes are waste products from the paper industry. They are created when waste paper is recycled in the pulper and absorb impurities such as plastics, small metal parts, foils and non-soluble paper. But what is the best way of recycling these waste products?

            Processing them into alternative fuels has proved to be the most effective way of recycling pulper ropes and paper production rejects. This yields two marketable materials: metal as well as high-calorific alternative fuels for energy production.

            UNTHA offers a cost-efficient, single-phase shredding system. Benefit from the following advantages:

            • Compact shredders, material handling and metal separation units require little space
            • Low operating costs thanks to single-phase processing concept
            • Perfectly processed material streams (alternative fuel and metal)

            Tried-and-tested processing concept
            The ropes are fed directly into the hopper via a material handler. The cutting unit shreds the material to a pre-defined size and the granulate is removed by a discharge conveyor. An overbelt magnet removes all metal parts from the material stream, resulting in a metal content with few impurities and a high-calorific alternative fuel. For this single-phase processing method, we offer a 1-shaft shredder in the XR class and a 4-shaft shredder in the RS class.
