The commonly used structures of shredders mainly include two-axis (or four-axis) shearing type, single-axis roller cutting type, and tearing type for coarse crushing.
1) Shear type shredder
The most common is the shearing type pulverizer, which has two to four knife shafts, and mainly relies on the principle of “shear and cut” to complete the pulverization process. The principle of this shredder is to crush objects like scissors.
2) Roll-cut mill
Roller-cut pulverizer is a roller-cut pulverizer structure. The machine is equipped with multiple blades on a rotating knife roller, which form a tangential cut with the fixed blades to complete the effect of material crushing.
3) Tear type coarse pulverizer
The principle of the tearing coarse shredder is to tear the garbage material by swinging the hook. This model is mainly used for coarse crushing.
