Large-sized Furniture Shredders Sofas And Mattresses Shredder For Fabrics Sponges Wood RDF Production Plant

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.

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%
