Large-sized Furniture Shredders Sofas And Mattresses Shredder For
Fabrics Sponges Wood RDF Production Plant
Large-sized furniture shredders such as sofas and mattresses adopt
a low-speed, high-torque design (15-60kW×2 motor power), and use
staggered blades to achieve shearing and crushing, which is
suitable for processing hard materials such as spring mattresses
and solid wood furniture. The sofa shredder has a feed size of
≤1200mm, a discharge size of 50-200mm, and a processing capacity of
3-8 tons/hour. The mattress shredder can process fabrics, sponges,
wood, and metal at the same time, and is equipped with an automatic
reversing anti-jamming function.
Performance characteristics of sofa mattress shredder
1. Unique tool design, easy maintenance and replacement
The raw materials of the tool are made of imported alloy steel,
with long service life and good interchangeability, which is
convenient for later maintenance and replacement of tools.
2. The main shaft is strong and has strong fatigue and impact
resistance
The main shaft is made of high-strength alloy steel, which has been
heat treated and processed with high precision for many times, has
good mechanical strength, strong fatigue and impact resistance, and
long service life.
3. Imported bearings, multiple combined seals
Adopting imported bearings and multiple combined seals, it has high
load resistance, long service life, dustproof, waterproof and
anti-fouling, ensuring the continuous and stable operation of the
machine.

Sofa mattress shredder applicable scope
Furniture
Large furniture such as old sofas, old mattresses, large wardrobes,
old tables, old chairs, old wooden frames, etc.
Old sofas (including metal springs/leather/sponge composite
structure)
Mattresses (spring layer + filling material)
Wooden furniture (tables, chairs/cabinets/doors and windows)
Other large wastes
Household appliance shells (refrigerator/washing machine shells)
Garden waste (thick branches/trunks)
Industrial waste (pallets/packaging boxes)
The detailed process of preparing RDF fuel from large waste such as
sofas and mattresses is as follows:
1. Pretreatment and coarse crushing stage
Chain conveyor: Large waste is evenly fed into the crushing system
through a chain conveyor
Double-axis waste crushing: A double-axis waste crusher is used
for primary crushing to break the mattress/sofa into 50-200mm
fragments, while separating metal parts such as springs
Magnetic separation and iron removal: The magnetic separator is
used to quickly separate the iron metal (such as mattress springs)
in the crushed materials, and the recovery rate can reach more than
95%
2. Fine processing stage
Secondary crushing: Use a double-axis shear crusher to crush the
materials for the second time, so that the particle size of
combustibles (sponge, cloth, wood) is reduced to less than 30mm
Wind separation: The wind separator removes heavy materials such
as stones and glass, and separates light combustibles (plastics,
fibers)
Drying and dehydration: Dry the combustibles after sorting, and
control the moisture content below 15% to increase the calorific
value
3. RDF forming stage
Homogeneous mixing: The dried material is conveyed to the material
mixing box by a belt to ensure uniform calorific value
High-pressure forming: The RDF forming machine squeezes the
material into cylindrical fuel rods with a diameter of 20-50mm and
a density of 0.8-1.2t/m³
Finished product packaging: The molded fuel rods are automatically
packaged for easy transportation to cement plants or power plants
as alternative fuels
Key equipment and technical advantages
Two-stage crushing system: The dual-axis + dual-axis crushing
combination achieves efficient volume reduction, with a processing
capacity of 8-15 tons/hour
Fully automated control: The entire line is equipped with a dust
removal system and intelligent sorting, reducing manual
intervention by 60%
Resource recovery rate: The final combustible recovery rate
exceeds 85%, and the metal recovery rate exceeds 90%
