Knowledge of double-shaft shear shredder

Dual-shaft shear shredders, referred to as shredders or crushers, are widely used in domestic waste, industrial waste, electronic waste, biomass, tire disposal and other fields.

1. Function introduction:
The biaxial shear shredder uses the principle of shearing and tearing between two relatively rotating knives to crush materials. Using "motor + planetary reducer", it has strong power and high operating stability. It is often used in environmental protection fields such as municipal waste disposal, resource recycling, and waste incineration pretreatment. This equipment has the characteristics of low speed and high torque, large shearing force, good shredding effect, low noise and good stability.

3. Working principle:
The crushing principle of the double-shaft shear shredder is that staggered blades are installed on the two cutter shafts. The two cutter shafts rotate in opposite directions through the shearing of the blades and the tearing of the knife teeth to achieve crushing. . The main shearing mode is the shearing effect of the adjacent movable knife blades, and the auxiliary shearing mode is the tearing effect of the movable knife teeth.

The blade of the movable knife will wear during normal use. After the wear reaches a certain level, it needs to be repaired or replaced in time. Otherwise, it will not only affect the output and crushing effect, but also affect the normal operation of the equipment.

The size of the gap between the two movable knives has an important impact on the output of the equipment.
