Introduction of Waste Plastics Crushing Processes

In the waste plastic foam recycling process, waste foam crushing is one of the most important processes, the volume of waste foam is reduced, which is convenient for subsequent processing. Foam crusher is a common facility to be used to crush plastic foam, such as EPS foam, XPS, EPP.

 

The waste plastic foam crushing process varies due to corresponding materials while different plastic foam materials have their own characteristics.
1. EPS(foam#6)/XPS
EPS and XPS belong to large lump material. Once crushed, waste EPS/XPS can be easily broken into small pieces. The basic principle of the process is to destroy the material's integrity depend on the shear strength and the impact strength. For this fragile brittle material, an EPS shredding machine is the best choice.

 

2. PE foam
PE foam pertains to soft small, broken material. The process of handling it has no difference with other foam materials. The only thing should be taken note of is to use low-temperature crushing because PE foam is elastic and soft. 

 

3. EPP foam
For ductile foam like EPP, shear-type foam crushing equipment is the most suitable one because EPP is easy to be affected by outside compression, bending impact, and other forces.

In addition, the extent of crushing equipment should be taken into account according to the needs. If crushing the large pieces into small pieces, using compression, impact, or cutting equipment; if putting small pieces into a fine powder, choosing abrasive grinding equipment.

Recovering end-of-life plastics and production offcuts requires meticulous preparation. Every year, a large number of plastics are collected from industries, local authorities, plastics manufacturers and businesses, and given a new lease of life. Find out how the industrial plastics recycling chain works.

Why shred your industrial plastic waste?

Plastics are used in many industries, for packaging, containers, transport pallets, etc. In the plastics industry, the industrial process generates production offcuts. All these elements, which can no longer be used, are considered plastic waste.

Because these plastics are unusable, they require considerable storage capacity. A specialized company can intervene directly in warehouses to collect waste in mixed trucks (several types of plastic can be collected at the same time). Properly processed in warehouses, plastic waste can be given a second life!

The advantages: money-saving, time-saving, limited waste storage, everyone can concentrate on their core business.

In addition, it allows companies to participate in the plastic recycling chain, creating new secondary raw materials that can be reused.

The aim of crushing plastic is to simplify the separation of elements of different natures (organic materials, paper, dust, etc.) which cannot be completely separated manually. Subsequently, grinding makes it possible to differentiate plastics of different densities, and therefore to ensure the quality of the final material.

Plastic processing: grinding, micronization, regeneration

Plastic waste is omnipresent in industry, used for a variety of packaging products for example. To reduce their ecological impact, the process of transforming plastic materials into crushed, granular or powder has become a common solution for recycling plastic waste and giving it a new life.

Here are the 3 ways to transform plastic.
