What is a Shredder?
Industrial shredders are high strength, low speed, high torque machinery. There are various shapes and sizes for cutting blades which are mounted on a solid rotor or shaft, or on multiple hex shafts, and rotated to produce a shredding / cutting step. Using the sturdy, hook-style cutting blades that spin at slower speeds can ensures that little or no dust is generated. Further more shredders can quietly crush large pieces and large amounts of raw material into smaller, random pieces between 1-5 inches due to its unique ability.
Shredders have many different models and are classified using the number of shafts; that is, depends on your application there are single axis, dual axis, and quad axis crushers for you to choose. Other common uses of shredders for recycling plastics include:
Shredders are extremely useful for the recycling of plastic films, especifically in an automated washing line. The films can be fed in batches, which means that large bales of film can be fed into the shredder. Packaging plastic film in large, compact packages is standard practice for most recycling centers where films are consolidated and trucked or shipped overseas to processing facilities. By packing loose films, recycling centers can save inventory space and the costs of the logistics can be reduced. Plastic film bales have many sizes depends on the type of packaging equipment are using and operator's experience. However the length, width and height of most films will be around 3 to 5 feet with each bale weighing between 500 and 1500 pounds.

- Tire or rubber recycling
- Metal recycling
- E-waste or WEEE recycling
- Product destruction for liability issues, including confidential documents, computer storage media such as hard drives, x-rays, expired products, obsolete stocks, pharmaceuticals and more
- Wood recycling: waste wood can be crushed to produce wood particles or boards
- Downsizing in wastewater treatment plants and other municipal applications
- Other solids: food destruction, pallets, steel and plastic drums, furniture, construction debris, containers, corrugated boxes, packaging, labels, and other bulky materials
