How Does a Plastic Granulator Work?

Everything You Need to Know About Plastic Reduction Technology

%%

In the world of plastic recycling, efficient reduction technology is the key to sustainable material reuse. The plastic granulator plays a central role in this. This powerful machine converts plastic waste into uniform granulate particles that can be reused in production processes such as extrusion or injection molding.

works, which components are crucial, and what to consider when choosing the right machine.

%%

• What is a Plastic Granulator? %%
• Cutting Chamber: A plastic granulator is a machine that reduces larger plastic parts – such as injection molding waste, pipes, bottles, or technical components – into smaller, uniform particles (granulate or “regrind”). These particles can be reused, reducing waste and lowering dependence on new plastic.
• %% Key Components of a Granulator
• %% Hopper (hopper):
• Drive System: %%
• The point of entry for plastic waste. Can be filled manually or automatically. %%

The actual reduction takes place here through a rotating rotor and stationary knives.

1. %% Rotor & Knives:
2. %% The rotor contains hardened knives that rotate at high speed. Together with fixed knives, a shearing action is created that cuts the plastic.
3. %% Sieve:
4. %% Only particles small enough to pass through the sieve openings. The sieve determines the final size of the granulate (e.g., 10–100 mm).

%%

A powerful motor (often 22–110 kW) drives the rotor. Energycle uses efficient V-belt drives.

• %% Discharge and collection system:
• %% The granulate is collected in a bin or pneumatically transported to the next processing stage.
• %% How Does the Reduction Process Work?
• %% Input:
• %% Plastic waste is fed in through the hopper.

• Plastic Production: %%
• Reuse of internal waste (sprues, failed parts). %%
• Automotive: %%
• Recycling of plastic parts and interior panels. %%
• Maintenance Convenience: Our models provide hydraulic access to the cutting chamber.

Maintenance and Safety

• Regular knife sharpening prevents quality loss and energy consumption.
• Sieve inspection prevents blockages and ensures constant output.
• Lubrication of bearings and control of V-belts extend the lifespan.
• Safety features such as emergency stops, interlocks, and protective caps are standard at Energycle.

Frequently Asked Questions (FAQ)

Which plastics can be processed?
PE, PP, PET, PVC, PS, ABS, HDPE and other thermoplastics – depending on machine configuration.

What is the difference between a shredder and a granulator?
A shredder reduces coarse and slow, a granulator fine and fast. Often both are used in series.

How often should the knives be replaced?
Depending on material and volume. Check regularly for thickness or increased power consumption.

Can wet plastics be processed?
Some Energycle models are suitable for wet material, such as after washing.
