Mattress Shredder Machine Sofa Furniture Crusher Recycling Plant For Furniture Mattress Sofa

A sofa and mattress shredder is an industrial device designed specifically for large, mixed-material furniture. It uses shearing, tearing, and squeezing to break down used sofas, mattresses, and other items into uniform, small pieces or particles. Its core function is to reduce the volume of bulky waste, recycle it, and facilitate its transportation. It is widely used in environmental recycling, wood processing, and metal recycling.

Working Principle

Power Drive System
Motor and Reducer: The motor rotates using electromagnetic force, which is then reduced and torque is increased by the reducer to ensure sufficient tearing force for the blades.
Spindle and Cutter Head: The spindle features a hexagonal design and undergoes a full quenching and tempering treatment, resulting in high wear resistance, high torque resistance, and resistance to bending and deformation. The cutter head is mounted on a rotating blade, which works in conjunction with a fixed blade on the frame to create a shearing action.
Crushing Mechanism
Shearing Action: The moving and fixed blades move relative to each other, cutting the material fibers. Tearing Action: The moving blade tip contacts the cylindrical surface of the spacer, tearing hard materials (such as wood and metal).
Squeezing Action: The torque and speed differential of the blade shaft create a tearing force, crushing soft materials (such as foam and fabric).
Intelligent Sorting: After crushing, the material undergoes magnetic separation, air separation, and vibratory screening to separate metal, wood, foam, and other materials.
Discharge Control

The screen determines the particle size, and unqualified materials are repeatedly crushed within the machine chamber until they meet the required particle size.
Metal materials are automatically discharged into a buffer device through a magnetic separator, while other materials are transported to a truck via an enclosed belt conveyor.

Applicable Materials
Metals: Scrap iron, car hulls, bicycle frames, motorcycle frames, metal briquettes, paint cans, pre-painted steel tiles, cans.
Wood: Furniture scraps, miscellaneous wood, branches, boards, wooden pallets, solid wood, tree stumps.
Plastics: Pipes, films, woven bags, plastic barrels, mobile phone cases, discarded fuel tanks.
Household Waste: Sofas, mattresses, clothing, waste fabric, tires.
Industrial Solid Waste: Leather, fabric, circuit boards, wire rope, refrigerator, air conditioner, and washing machine casings.
Special Materials: Concrete blocks (requires construction waste treatment equipment), electronic waste (requires pollution prevention design).

Furniture shredder blade features:
Material and Craftsmanship:
Highly wear-resistant alloy steel: such as SKD-11, 42CrMo, and Cr12MoV, with a hardness of HRC58-62 and strong impact resistance.
Surface Treatment: Salt bath furnace quenching or vacuum furnace quenching improves wear resistance and service life.
Overlay Technology: Multi-layer overlay welding (single layer height ≤ 8mm) enhances blade hardness and reduces wear.
Structure and Specifications:
Cutter Roller Type: Dual-shaft or quad-shaft designs, with 3-12 claws to accommodate different material characteristics.
Connection: Hexagonal connection ensures uniform force distribution, and modular blades allow for independent replacement of individual blades for efficient maintenance.
Size Range: Diameter 200-500mm, thickness 20-55mm, with internal holes typically hexagonal or round (with keyway). Special Design:
Spiral cutter disc: Double rollers interlock with a gap of ≤0.5mm, precisely controlling the discharge particle size (1-5mm).
