double shaft shredder

The double-shaft shredder is an efficient and durable industrial shredder, which is widely used in waste recycling, garbage disposal and resource recycling. Its core design uses two parallel knife shafts to tear the material into small pieces through the shear force generated by relative rotation. It has the characteristics of strong processing capacity and wide adaptability.

The double-shaft shredder drives the two knife shafts to rotate synchronously in the opposite direction through the motor. After the material enters the crushing chamber, it is bitten, sheared and squeezed by the blades on the knife shaft, and finally decomposed into uniform fragments. The knife material is usually high-strength alloy steel, which is wear-resistant and impact-resistant. Some models can also be equipped with hydraulic systems to achieve overload protection or automatic reversal functions to ensure stable operation of the equipment.

The equipment can handle a variety of hard or flexible materials, including:

Metals: scrap iron, aluminum cans, car shells, wires and cables, etc.;

Plastics: waste home appliance shells, tires, pipes, plastic barrels, etc.;

Others: wood, paper mill waste, domestic garbage, etc.

The size of the shredded material can be controlled by adjusting the knife gap or the screen aperture, usually between 10-100mm, to meet the needs of subsequent sorting, smelting or compression.

Double-shaft shredders are often combined with the following equipment to form a production line:

Conveyor: automatic feeding to improve efficiency;

Magnetic separator: separate the iron components in metal scraps;

Baler: compress the scraps to reduce the volume;

Sorting equipment (such as eddy current separator): further screen non-metallic impurities.

Double-shaft shredders have become the core equipment of the resource recycling industry due to their powerful crushing capacity and flexibility. Reasonable selection and matching of auxiliary systems can significantly improve processing efficiency, reduce operating costs, and help environmental protection and sustainable development.
