Municipal Solid Waste Shredder with 1-10 Cm Output 100-50000 Kg/hour Capacity and 5~10 Years Lifetime

A municipal solid waste shredder is a mechanical device specifically designed to process municipal solid waste (MSW). MSW has a complex composition, encompassing a wide range of soft, hard, and ductile waste, such as plastics, rubber, fabric, branches, small metals, and organic waste. This device uses powerful mechanical force to break this mixed waste into small, uniform particles or chunks for subsequent sorting, recycling, transportation, and reprocessing. It is a key component in the MSW treatment process, helping to improve waste treatment efficiency and achieve resource recycling and reduction goals.

• Power Transmission: The motor provides power, which is transmitted to the shredder's main shaft through transmission devices such as pulleys, speed reducers, and couplings, causing the main shaft to rotate steadily at the set speed and direction. Multiple motors (such as dual or quad motors) are typically used to ensure sufficient torque and power to process complex MSW.
• Material Input: A feed system (such as a hopper or conveyor) feeds MSW evenly and continuously into the shredder's shredding chamber. The feed system controls the feed rate, prevents overload, and ensures a steady flow of waste.
• Crushing Process: Within the shredding chamber, specially designed cutting tools (such as high-hardness alloy blades and claws) are mounted on the main shaft and arranged in a specific pattern. Once domestic waste enters the chamber, the high-speed rotating cutting tools apply shearing, squeezing, and tearing forces to the waste.
• Discharge: Crushed waste particles or lumps are discharged through the discharge port. The discharge size can be controlled by adjusting parameters such as the spacing between the cutting tools and the main shaft speed to meet subsequent processing requirements.

Soft waste: Materials such as plastic bags, plastic film, rubber products, and fabrics have a certain degree of toughness and elasticity, making them effectively shredded by the shearing action of the shredder.

Hard waste: Materials such as branches, wood blocks, and small metal products (such as cans and metal tools) are broken into smaller pieces through the squeezing and tearing forces of the shredder.

Mixed waste: Complex waste, such as municipal solid waste, contains a variety of mixed components. Shredders can handle this waste in a comprehensive manner.

• Metals: Scrap steel, aluminum alloy, copper, stainless steel, and other metal products
• Plastics: Various plastic products, such as plastic film, plastic pipes, plastic containers
• Rubber: Rubber products such as used tires, rubber hoses, and rubber mats
• Wood: Scrap wood, wooden pallets, wooden furniture, and tree branches
• Paper: Waste paper, cardboard, and cartons
• Fiber: Fiber products such as used clothing, carpets, and non-woven fabrics

• Wide Processing Range: Capable of processing a wide range of waste components within municipal solid waste
• Efficient Crushing: Rapidly shredding large, complex municipal solid waste into smaller, uniform particles
• Effective Crushing: Crushing waste into appropriate sizes facilitates subsequent sorting and recycling

(Special - customized types can be customized according to the size and type of materials.)

Mixed household waste is conveyed to a pre-processing area via conveying equipment. Large items are manually or mechanically sorted, followed by magnetic separation to remove metals. The waste then enters a dual- or quad-shaft shredder, where high-speed rotating blades apply shear, compression, and tearing forces to the waste, breaking it into uniform, small pieces (approximately 10-30 cm in size). The shredded material is conveyed via a conveyor to a screening device for particle size classification.
