The family business. The young entrepreneur and visionary, Peter Rössler, recognized the potential of waste recycling early on and founded Weinsberg Maschinenfabrik – or WEIMA for short – in 1980. After the turn of the millennium, Martin Friz succeeded in bringing about the generation shift and has now been running the business since 2003. Global leader. WEIMA produces more than 1,200 shredders, briquetters and drainage presses per year on a production area of approx. 65,000 sqm with more than 300 employees worldwide. Since its foundation, about 40,000 machines have been delivered...

REDUCE. REUSE. RECYCLE. WEIMA stands for active environmental protection and for robust shredding technology that’s “Made in Germany”. Our machines lay the foundation for a resource-saving future and are at the beginning of many recycling processes. AN APPRECIATION FOR WASTE MATERIALS As a recycling specialist, we see it as our duty to contribute to a clean planet. WEIMA shredders, granulators, briquetting and drainage presses are thus becoming ever more sophisticated, productive, and above all – energy-efficient. SUSTAINABLE FOR INDUSTRY AND TRADE The wide selection of machines and options...

Plastics With many thousands of plastic shredders delivered, there are hardly any applications that we have not already processed. These include classic items such as purge, crates, pallets, pipes, containers, molded parts, and post-consumer waste such as PET bottles or packaging. But also particularly tear-resistant materials such as rubber or films made of BOPP, as well as fabrics and fibers made of aramid, Kevlar or carbon. “With the high volumes of plastic waste in the world, sustainable disposal concepts are particularly important, and shredding is the foundation for this.” Gunter...

Wood If you want to generate energy from your waste in an environmentally friendly way, you can't do without wood as a raw material. The wood waste, which is shredded into chips, can be used for direct heat generation in wood burning oven or for the production of briquettes. Typical applications are all kinds of hard and soft woods, old wood, OSB and MDF scraps, veneer, plywood, stairs, doors, and pallets. And don't worry. Their nails and screws are simply shredded as well. Later they can be conveniently separated by means of a magnet. "The first WEIMA shredders of the 1980s were used for...

50 Tons This is the throughput achieved by a WEIMA single-shaft shredder in the production of high-quality refuse-derived fuel. Waste and substitute fuel Whether as a stand-alone solution or firmly integrated into a production line – thanks to innovative drive concepts, WEIMA is a full-range supplier for the single-stage as well as multi-stage processing of all types of waste. Robustly designed pre- and post-shredders effortlessly shred industrial and commercial waste, municipal waste as well as bulky and household waste. The output material is ideal for producing high-calorific...

SHREDDING TECHNOLOGY At WEIMA you get everything from a single source: planning, design, machine, control cabinet, control, software, conveyor technology, support, maintenance, wear parts and spare parts. We make all this and much more possible with 40 YEARS OF RECYCLING KNOW-HOW.

SINGLE-SHAFT SHREDDERS Maximum robustness and the highest precision – WEIMA shredders prove day in and day out to operators all over the world that this balancing act is possible. Whether compact machines that have been sold thousands of times over, such as the WL 4, or huge high-end shredders like the W5.18 – our shredders work according to the same principle.

Feeding of material to the rotor with the ram Size reduction with rotor and counter knives Definition of particle size via screen Loading of material into the hopper Discharge of the shredded material via suction, screw conveyor or conveyor belt

ROTOR AND CUTTING TECHNOLOGY To achieve the desired result from a shredder, it’s important to select the right combination of rotor, knives and counter knives. Selecting the right specifications for each material type requires a high degree of experience. ROTOR No two applications are alike. But one thing remains: the rotor is the heart of the shredder. It is fitted with cutting blades and, depending on the material and the machine, rotates between 30 and 400 revolutions per minute. F rotor Controlled feed behavior, ideal for flexible materials such as filaments, films or veneer V rotor...

Cutting knives come in many different sizes and shapes. Knife holders are either welded or screwed onto the rotor. The exact setting of the cutting gap between the cutting knife and the counter knife is of particular importance. This is where the actual size reduction takes place – similar to a pair of (very large) scissors. For applications free of foreign materials For better material feed Extra concave For flexible materials CrossCut For more cuts For significantly longer tool life Trapezoid For extreme applications Counter knives While the rotor cutting knives rotate, the counter knives...

The screen mounted below the rotor defines the material size (particle size) that will result from shredding. As a rule, the larger the holes, the coarser the shredded material. ( The classic standard screen is universally applicable for almost all types of material. 10 - 150 mm diameter The extended hole area (more holes per m2) increases the throughput. Despite low web thickness, the structure is particularly stable. 20 - 150 mm wide openings DID YOU KNOW? Modelled after nature - the bionic design of the honeycomb screen was inspired by dimensionally stable honeycombs.
