Dual-shaft shredder—widely used in the fields of plastic products, waste plastics, wood, scrap tires, scrap metal, waste household appliances, and other related solid waste utilization. 2. The entire machine adopts a modular design, with corresponding tooth structures, blade arrangements, blade materials, and chamber sizes configured based on different material characteristics and production requirements. 3. The top of the shredder is equipped with a sealed silo, effectively preventing dust from escaping during the shredding process. 4. The lower part is the shredding chamber, where the shredding method is shear-based. 5. The shredder boasts high shredding efficiency, excellent shredding results, long service life, energy savings, environmental friendliness, and intelligent reliability. 6. It can completely destroy various hard and ductile materials in domestic waste. 7. Through tearing, squeezing, and shearing by the blade shafts, various types of waste—such as hardwoods, thin iron sheets, and ductile materials—are shredded to sizes below 50mm. The shredded domestic waste is then sent to subsequent equipment for further sorting. 8. It is mainly suitable for shredding and volume reduction tasks in large-scale waste treatment centers.
