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

A furniture shredder is a mechanical device specifically designed for processing waste furniture and bulky waste. It breaks the material into uniform small pieces or particles through physical processes such as shearing, tearing, and squeezing. Its core function is to reduce the volume of waste furniture, recycle it as a resource, and facilitate its transportation. It is widely used in environmental recycling, wood processing, and metal recycling.

Working Principle

Power Drive:
Two blade shafts are driven by hydraulic or electric motors to rotate in opposite directions, creating relative motion. The moving blades on the blade shafts work together with the fixed blades (or spacers) to generate shear force.
Crushing Mechanism:
Shearing Action: The adjacent cutting edges of the moving blades create shearing, cutting the material.
Tearing Action: The blade tips of the moving blades contact the cylindrical surface of the spacer, tearing the material fibers.
Crushing Action: The torque and speed difference of the blade shafts create a tearing force, breaking tough or sticky materials. Discharge Control:
The crushed material is discharged through a screen, with particle size determined by the screen's aperture. Unqualified material is repeatedly crushed within the machine chamber until it meets the required particle size.

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).
