Applications in PVC Foam Board Manufacturing
1. Waste collection
Recycling of edges, defective products, boot material and other production waste materials
2. Crushing process
The use of grinding mill will be crushed to 40-80 mesh fineness of waste materials, supporting magnetic separation equipment to remove metal impurities
3. Recycling
Direct reuse: 15-25% of the proportion of mixing into the new material. Pelletizing reuse: add foaming agent and other additives to make recycled particles
4. Production optimization
Improve the homogeneity of raw material mixing, improve the stability of foaming, reduce the melt extrusion resistance.
5. Benefits
Reduce raw material costs by 20-35%, waste disposal costs by 40-60%, in line with the requirements of environmentally friendly production
Advantages of PVC Grinding Machines
1. Reduce cost and increase efficiency
Directly save 15-25% of raw material cost, reduce 40-60% of waste disposal fees
2. Improve quality
Foam uniformity improvement, product density deviation ≤ 3%, surface finish improvement.
3. Green production
90% waste recycling, meet REACH and other environmental certifications.
4. Optimize process
Reduce extruder load by 10-15%, increase production efficiency by 8-12%.
Key control points
1. Crushing fineness control in 40-80 mesh
2. Different colors / formulations of waste classification and treatment
3. Add the necessary additives before reuse
