The role of pre-crushing:
Reduce material size: decompose large pieces of car shells into 50-200mm fragments to reduce the load of subsequent equipment.
Improve sorting efficiency: After pre-crushing, metals and non-metals (such as plastics and rubber) are easier to separate, improving the purity of recycling.
Reduce energy consumption: Compared with direct smelting or fine crushing, pre-crushing can reduce energy consumption by more than 30%.
Protect equipment: Prevent oversized metal parts from entering the crusher directly, reduce tool wear and equipment failure rate.

The scrap car shell shredder is a hammer crusher, and its working principle is based on the high-speed rotating hammer to hit and tear the material. The equipment adopts advanced crushing technology, and the hammer on the rotor is driven by a high-speed motor, so that the hammer takes turns to hit the scrap car shell entering the cavity. Under the strong action of the hammer, the car shell is quickly broken into small pieces, and then screened through the screen to achieve the separation of metal materials and plastic parts.

The new energy vehicle shredding and sorting production line consists of shredders, conveyors, dust collectors, control refrigerators and other equipment, which can realize automated operation and improve production efficiency. It can separate and classify recyclable materials in automobiles and has environmental protection characteristics to control dust and noise pollution and be equipped with safety protection devices. However, the production lines of different manufacturers differ in structure and function, and the operation should be adjusted according to actual conditions.
