PS-Series Plastic Crusher

A granulating crusher that brings shredded or loose plastic down to flake size for washing, drying and granulation, with screens to set the output.

Application

The stage that sets flake size

Washing efficiency and granulator performance both depend on particle size. The PS series is specified by the size the next stage needs, not by nominal tonnage alone.

Material fit

PET bottles, film, pipes, sheet, woven bags, jumbo bags and ABS/PS housings.

Design points

SKD-11 blade material, water-cooled bearing housing and anti-blocking chamber design.

Output

Flake size set by screen; screens are interchangeable for different downstream requirements.

Published figures. Output size depends on screen selection; capacity depends on material and feed size.

Process

Blade options

Blade geometry is matched to the material rather than fixed at one profile.

V-type

Suited to film and woven bags — fine output at high throughput.

Step type

Suited to sheet, pipe and board — strong crushing force.

Claw type

Suited to PET bottles and hard plastic — efficient with easier blade changes.

Maintenance

Clean the chamber each shift, inspect blades weekly, grease bearings monthly.

FAQ

Common questions

What flake size can the crusher produce?

Screen choices run from 3 mm to 15 mm, giving an output typically in the 5-20 mm range depending on material.

Does the crusher handle whole PET bottles?

Yes, with the appropriate blade profile and feed opening. For very bulky feed, a shredder is placed ahead of the crusher.

Can it crush metal?

No. The crusher is not designed for metal or stone; metal removal is recommended upstream.

How is the right model chosen?

By required flake size, hourly capacity, feed size and the material type — the model is confirmed with the rest of the line rather than in isolation.
