Pretreatment system includes front-end feeding belt conveyor, refrigerator pretreatment drum conveyor line, dismantling workbench, refrigerant recovery system, intelligent compressor drilling and oil filtering device, and negative pressure dust removal and purification system.

The mainstream combination of the broken system is 'double shaft shredder + vertical crusher.' The new type of double shaft shredder features blades with a three-stage kneading design, improving the crushing efficiency. It possesses characteristics such as high processing efficiency, low power consumption, pure separation of capacity, and high value

It is mainly used in waste derived fuel (RDF) (domestic waste, industrial waste, waste wood, waste paper, waste tires, waste plastics, carpets and textiles; product / document safety damage (tearing up documents, unqualified products or out of season products, drugs, etc.); Waste disposal (medical waste, radioactive materials, organic waste, paper fiber, etc.).

Vertical Crusher is primarily used in the field of recycling for scrap metal, serving as secondary processing for metals pre-shredded by a dual-shaft shredder. It aims to clean materials adhering to the metal surface and separate metals of different materials, facilitating subsequent sorting by other equipment such as magnetic separators and eddy current separators.

The Double Shaft Shredder is suitable for waste recycling in various industries, handling the crushing of electronic waste, scrapped cars, lightweight and thin scrap steel, household waste/bulky waste, industrial hazardous waste, medical waste, and other types of discarded materials.
