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!

      • 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!

      • 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.

      • TR2500/3200/4000

      • Reliable post-shredder for secondary fuel recycling with very high throughput
         

        The reliable TR series was specifically designed for re-shredding fractions with high calorific value and is mainly used for secondary fuel processing. The TR is a high-performance RDF/SRF shredder that also generates high-quality end fractions in addition to having high throughput performance.

        This re-shredder contains quite a bit of smart technology to increase your company's outputand the quality of your alternative fuel. The large rotary shear diameter of 1,100 mm enables a large perforated screen surface thereby providing high throughput performance. In addition, this re-shredder comes standard with a frequency transformer that regulates the rotor speed thereby optimizing the throughput performance. 

        The low TR series operating costs are a direct result of the low maintenance costs and the very long service life. Long maintenance intervals, short replacement time for cutting tools and an automatic central lubrication system render this re-shredder particularly low maintenance. Another highlight of this RDF/SRF shredder is its automatic foreign objects hatch. When foreign objects are pulled into the machine, the hatch opens automatically and prevents damage to the cutting unit.

            Utilization areas and fraction sizes of alternative 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
          • Plastics

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

            Due to its versatility and ease of processing, plastics are very versatile materials that are frequently used in industrial mass production. The waste plastic generated can be recycled through shredding, washing, and subsequent granulating, thus producing a reusable recycled material. Aside from recycling, plastic waste can be used for energy generation after shredding.

            Our shredders were developed specifically for the processing of plastics. 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.
          • Electronic scrap

          • Our customized shredders enable you to efficiently shred electronic scrap and they align perfectly with your recycling system. Particle size can be adjusted such that metals and non-metals can be separated and recycled as efficiently 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 precious metals that can be recovered during the recycling process. To ensure a high yield during the recovery process, it is important that the shredding generates a minimal amount of fine particulate matter.

            Our low-speed, 4-shaft shredders are particularly suited for this process. The low speed ensures that circuit boards and old devices are carefully shredded with little dust. The shredded material is ideally suited for e-scrap separation systems and subsequently for refiners, where precious metals are recovered.
          • Metals

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

            Metals are important raw materials for industry and can be recycled over and over. Recycling metals saves valuable raw materials and energy as opposed processing new material from ore.

            Our rugged shear shredders have been proven over decades of reliably shredding not only light metals such as aluminum, magnesium, Al-Mg alloys, copper, or nickel, but also harder metals such as iron, zirconium, titanium, and sheet steel.
          • Wood waste

          • 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.

          • Battery shredding

          • Batteries are used in everything from flashlights to cars, from remote controls to computers and come in a wide variety of shapes and sizes. At UNTHA, our battery shredders can handle every kind of battery, from button cells to EV batteries and are the perfect fit to your battery shredding solution.

            Batteries are an integral part of our daily life, from powering up our phones and other electronic devices, to supporting everything from computers to cars. Because of their wide range of uses, and their relatively short lifespans, a large amount of batteries are discarded every year. Adding to the problem is the fact that batteries contain heavy metals and toxic chemicals, so their safe disposition is essential. By recycling batteries, hazardous materials are kept out of our soil and water and valuable metals can be reclaimed.


            UNTHA’s multi-purpose four-shaft shredders are ideal for battery shredding because they operate with low speed and high torque. This means less noise, less dust, and less vibration, which makes the machines more durable and more pleasant in your workplace. They are service-friendly and require little maintenance.

          • Paper and cardboard

          • UNTHA offers customized solutions for shredding paper and cardboard. Our experienced engineers can optimize the shredder configuration to best meet your needs and ensure a perfect shredding result.

            Paper and cardboard are valuable raw materials that play an important role in recycling and in the waste processing industry. The easy recyclability of cellulose permits economical and environmentally friendly reuse of paper. Before shredding, the material is sorted, foreign objects are removed, and then the homogeneous is material shredded.
          • Ragger wire

          • 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.

            Ragger wire or reject are secondary raw materials that are created when waste paper is recycled. The pulper ropes must not be landfilled due to their material composition and must therefore be recycled accordingly – in most cases through shredding and subsequent separation of metals, glass and stones, etc.

            Our rotary shears or 2-shaft shredders together with our 4-shaft technology are very well suited for this application case. The advantage of the 4-shaft machines lies in the fact that the pre- and re-shredding occurs in one process step.
          • Organic waste

          • UNTHA shredders process biological and biogenic waste to generate an optimal material for utilization in a biogas plant or for disposal. The application ranges from food waste and expired goods including packaging, to slaughterhouse waste.
