Dual-shaft shredder—widely used in the fields of plastic products, waste plastics, wood, waste tires, scrap metal, discarded household appliances, and other related solid waste recycling applications. 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 involves shear tearing. 5. The shredder offers advantages such as high shredding efficiency, excellent shredding results, long service life, energy efficiency, environmental friendliness, and intelligent reliability. 6. It can completely destroy various hard and ductile materials in municipal solid waste. 7. Through tearing, compression, and shearing by the blade shafts, various types of waste—including hardwoods, thin metals, and ductile materials—are shredded to sizes below 50mm. The shredded municipal solid waste is then sent to subsequent equipment for further classification. 8. It is primarily suitable for shredding and volume reduction tasks in large-scale waste treatment centers.
