Working principle and structure of double shaft shredder

The dual-shaft shredder originated in the European continent in the 1980s and was originally designed to crush domestic and industrial waste. The double-shaft shredder is a double-shaft shearing shredder that crushes materials into small-size materials by cutting, squeezing and tearing the materials. The emergence of dual-shaft shredders has made up for the limitation that hammer crushers, jaw crushers and other crushers can only crush brittle and hard materials such as coal, salt, gypsum, bricks, limestone, etc., and can treat clothes and branches. Soft and tough materials such as, wood, film, plastic barrels, electronic waste, and medical waste can be broken into small pieces for recycling.

Working principle and structure of double shaft shredder:

working principle

The double-shaft shredder is driven by an electric motor or a hydraulic motor. The cutters are made of special alloy steel and are controlled by a programmable logic controller. It can automatically reverse when encountering hard objects. The discharge size can be designed according to user requirements. The speed of the cutter shaft is generally 10-70 revolutions per minute. The high speed of the motor is reduced to the low speed of the cutter shaft through the reducer, so the low speed double shaft shredder has the characteristics of high torque, energy saving, low noise, low dust and so on.

The main components

The main components of the double-shaft shredder are: motor, reducer, knife shaft, crushing knife, knife box, electric control and frame, according to different crushed materials can be equipped with pushers, fire extinguishing equipment, etc.
