Yes, Plastic dustbin crusher machines do exist, and they are a standard piece of equipment in the plastic recycling industry.

XINYI MACHINERY give you a more complete technical answer:

1. Confirmation of XINYI MACHINERY
XINYI MACHINERY is a China leading manufacturer of shredders and crusher machines/crushers, plastic extruder granulators, and other recycling machines.

2. The Technical Difference for Dustbins
Crushers for dustbins usually fall into two categories, depending on the bin's size and wall thickness:

· Small/Thin-Walled Dustbins (e.g., household bins): A standard heavy-duty plastic crusher (granulator) with a rotor diameter of 300-500mm can handle these directly.

· Large/Thick Industrial Dustbins (e.g., 120L, 240L, 360L wheelie bins): These require a double-shaft shredder first. Because large bins are hollow and tough, a standard crusher can’t grab and it will damage the rotor. The process is: Shredder (for rough size reduction)  Crusher/Granulator (for fine particles).

3. Key Features to Look For
If you are evaluating a machine (like XINYI or other brands) for crushing plastic dustbins, ensure it has:

· V-rotor or T-rotor design: To prevent "bridging" where whole bins get stuck.

· Shaft speed: Low-speed (80-120 RPM) for shredding large bins; high-speed (400-600 RPM) for crushing smaller bins into regrind.

Summary: You are right to look for a dedicated machine. For small dustbins, a standard crusher works. For large wheelie bins, a low-speed single-shaft shredder is the correct tool.
