What are plastic lumps?

Plastic blocks generally refer to block-shaped objects made of plastic material.These plastic blocks can be directly processed from raw materials, or they can be formed from waste plastic products after crushing, compression, etc.Plastic blocks come in a variety of shapes and sizes, they can be cubes, cuboids or other irregular shapes, and their size can also be adjusted as needed.

Why are we recycling plastic lumps?

During injection molding production, there are often production waste and scrap. These occur primarily when molded parts do not meet the desired specifications, edge trims have to be made or injection molded parts are cast on. Moreover, plastic waste also occurs during production breaks, machine tests or in the start-up phases of the machines. If the waste material is pure, it can be returned to production on-site. The recycling of start-up lumps reduces the amount of waste and thus effectively reduces the impact on the environment and on disposal costs.


How to recycling plastic lumps?

This waste molding plastic usually is in very solid and hard pieces, so shredding or crushing is the initial recycling process of these molding plastic scraps. For large molding plastic scraps (purgings), it is usually shredded by a single-rotor/shaft shredder – actually the purgings are shaved into plastic flakes by the high-speed cutting rotor of the single shaft shredder. Small molding scraps, can be directly granulated by small-sized min granulator. After shredding or granulating, this scrap molding plastic is then turned into regrind. Regrind is usually mixed with virgin compound at a predetermined percentage for remolding. Using regrind is a great way to reduce cost, optimize material usage, and reduce demand for natural resources.

Plastic lumps recycling machine process:

In order to optimally prepare plastic waste for extrusion lines, it must be shredded to the smallest possible particle size. Usually, this is done in a two-stage process, consisting of a pre-shredder and a post-shredder, which are connected to each other with conveyor technology (conveyor belt or screw conveyor).
While the pre-shredder shreds the plastic to a size of approx. 20-60 mm, the granulator grinds the material to approx. 3-12 mm.

Plastic lumps shredder: used for recycling PE PP PVC PET PS ABS lumps, waste plastic pipes, plastic bottles, plastic baskets, plastic shells of household appliances (e.g. TV, computer, refrigerator, washer machine, etc), plastic boards and so on.

Crusher: plastic lumps can be crushed, then get 3-12mm plastic scraps;
