Mattress Shredder Machine Sofa Furniture Crusher Recycling Plant
For Furniture Mattress Sofa
Products Description
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).
Advantages
Efficient Volume Reduction and Resource Utilization
Volume Reduction: Reduces the volume of large waste by 60%-80%,
reducing transportation and storage costs.
Resource Conversion:
Wood: Converted into biomass fuel, wood pellets, or composite
materials.
Metal: Recycled into new metal products.
Sponge/Fabric: Processed into filler or industrial raw materials.
Springs: Reprocessed for new furniture manufacturing.
Mixed Material Processing
Multi-Material Compatibility: Can process both hard (wood, metal)
and soft (foam, fabric) materials simultaneously, eliminating the
need for pre-processing and sorting.
Large Item Handling Capability: The robust blade shaft structure is
capable of shredding thick furniture (e.g., mattress springs can
cut through 12mm diameter steel wire in 3 seconds).
Environmental and Economical
Low Carbon Emissions: Shredded materials can be converted into RDF/SRF as an alternative fuel for power plants and cement plants,
reducing coal consumption.
Dust Suppression System: Equipped with enclosed conveying and dust
suppression systems, meeting environmental standards.
Low Maintenance: Utilizes blade overlay welding and finishing
technology to extend blade life and minimize downtime.
Operational Stability
Low Speed, High Torque: Reduces shaft tangling and seizures, and
features automatic overload protection to ensure continuous
operation.
Modular Design: Blades can be replaced individually, enhancing
maintenance efficiency.

The bulky waste shredding and sorting line efficiently processes
large pieces of waste, enabling resource recycling and harmless
disposal. The general process flow is as follows:
Pretreatment
Bulky waste is manually or mechanically loaded onto a conveyor for
initial sorting, removing non-trash items (such as rocks and large
metal objects) and hazardous materials (such as glass and sharp
objects) to prevent damage to downstream equipment.
Shredding
The pre-treated bulky waste is conveyed by a conveyor to a
shredder. The shredder uses the shearing, squeezing, and tearing
forces generated by the rotating blades to break the bulky waste
into smaller pieces, typically 5-30 cm in size, for subsequent
sorting. Common shredded items include used sofas, mattresses,
furniture, and large appliance casings.
Magnetic Separation
After shredding, the material enters a magnetic separator, where
the magnet's attraction to ferromagnetic materials (such as nails,
wire, and metal parts) separates the ferrous metal for recycling.
Eddy Current Separation
After magnetic separation, the material enters an eddy current
separator. This device uses an alternating magnetic field to
generate eddy currents in non-ferrous metals. The magnetic field
generated by the eddy currents interacts with the original magnetic
field, repelling the non-ferrous metals and separating them. It
primarily separates non-ferrous metals such as copper and aluminum.
Wind separation
The airflow generated by the fan separates lighter materials (such
as plastics and fabrics) from heavier materials (such as stones and
ceramics) by taking advantage of differences in material density
and suspension speed. The light materials are transported to a
collection device, while the heavier materials fall into other
collection areas.
