Plastic Shredder Advantages

People give different names to such waste, like plastic purges, plastic lumps and plastic blocks. Here in Wiscon Envirotech, we realize the huge incentive to reclaim plastic purges and lumps using a plastic shredder machine. Instead of selling tons of plastic scrap, the plastic processors can actually recycle and reuse the plastic lumps. Shredding the plastic lumps into smaller regrind at 12mm, which is close to virgin grade.plastic shredder for plastic lumps

How are plastic lumps created?

For thermoforming, the plastic lumps are caused by improper tuning of machines.

Secondly, switching of molds and masterbatch, as well as purging, can form lots of plastic lumps.

Thirdly, in the process of injection molding, runners, purges, trims and rejects are the main source of plastic scraps.

Overall, plastic production involves changes and interruptions often generated plastic lumps.

If the waste material is pure, for example, no metal waste, then it can be returned to production on site. The recycling of start-up lumps reduces the amount of waste and transportation costs and virgin material costs.

The following are some examples of plastic scrap produced in the means of blow molding, extruding, injection molding and thermoforming.

Adds-on and Customization of Shredding Systems

Infeed Conveyor: Automatic material infeed by belt conveyor or screw conveyor. A inclined chute faciliates forklift or crane.

Output Collection: tThe shredded materials can be cyclone collected (Blower), belt conveyor or screw conveyor.

Shredder Rotor: 3 types of rotors avail. Other than our standard rotor, one for plastic films or flexible materials, the other is super challenging and hard objects.

Elevated Rack: Facilitates to your equipment or ease to connect with corresponding equipment.

Motor: Increase motor or change to hydraulic motor.

Vertical Pusher: A verical ram force feed materials against the rotor. This increase shredding efficiency and capacity

Shredding Chamber: Increase dimension for shredding oversized items.

Lid: Prevents particles from flying out of shredding chamber.

Plastic Shredder Conclusion

A plastic shredder is versatile in dealing with plastic waste. Shredding and Granulating is the method of recycling the material back right into a granule form.
