Frequently Asked Questions about Granulating

What is a granulating machine?

Granulator, also known as crusher or grinder, is a size reduction machine used for grinding various materials into small and uniform particle sizes. … Granulator machine is ideal for crushing bulk waste materials such as various scrap plastic products like PET, HDPE, PP, PE, or PVC.

What does a plastic granulator do?

A Plastic Granulator is a machine used for breaking down plastic products for recycling. These machines come in a variety of types for industries and workshops and the various sizes of plastic products.

What are granulators used for?

Granulators are essentially rotary grinders that are used to grind scrap parts and melt delivery systems (sprues and runners) into feedstock sized granules for reprocessing. This allows the molder to reduce waste and produce components more cost-effectively.

Can you grind plastic?

Demand is growing for recycled plastics. Plastic grinding is the fastest, easiest way to process your plastics from PVC to PET back into reusable material.

What is plastic granulate?

Plastic granules (granulate) are the basic product from which plastic products are made. New plastics are usually supplied to processors in the form of granules. Re-granulate refers to recycled plastic from production waste.

How is plastic granulate made?

Production of PE based plastic –poly(ethylene) is processed in a factory to make plastic pellets. The pellets are poured into a reactor, melted into a thick liquid to cast into a mold. The liquid cools down to harden into a solid plastic and produce a finished product.

What is a dry granulator?

Dry granulators are machines used for dry granulation. Dry granulation is a type of granulation process in which granules are formed without using a liquid solution. The formation of dry granules requires dry powder densification and for agglomeration.

What is the difference between a shredder and a granulator?

Heavy-duty “hog” granulators are used to handle large, heavy parts and purgings. Generally, granulators operate at higher speeds with relatively low torque. Shredders, on the other hand, tend to operate at lower speeds (100 to 130 rpm) with high torque that allows them to chew through almost anything.

What is the difference between grind and shred?

The difference is that shred is to cut or tear into narrow and long pieces or strips while grind is to reduce to smaller pieces by crushing with lateral motion.
