Industrial plastic crushers play a vital role in size reduction for recycling processes. These powerful machines transform various plastic materials into uniform flakes suitable for washing, extrusion, and pelletizing operations.
Types of Plastic Crushers
1. Single-Shaft Crushers
-
Basic models for general-purpose crushing
-
Throughput: 100-500 kg/hour
-
Common applications: PET bottles, HDPE containers
2. Double-Shaft Shredders
-
Shear-type cutting action
-
Throughput: 500-3000 kg/hour
-
Handles: Thick-walled items, pipes, profiles
3. Granulators
-
Precision cutting for small flakes
-
Screen-controlled output size
-
Specialized for: Film, fibers, soft plastics

This breakdown of plastic crusher types is super helpful! Been in recycling for 5 years and learned new stuff today.
The PC-1000 model seems perfect for our e-waste recycling needs. Does anyone have experience running ABS plastic through it?
Wish more manufacturers would highlight noise levels upfront. 85dB is LOUD without proper hearing protection!
The maintenance section is gold – blades go dull way faster than people expect in commercial operations.
“80-90% volume decrease” sounds impressive until you see the energy consumption numbers 😬
Anyone else notice how single-shaft crushers became twice as efficient compared to 2016 models?
Pro tip: Always keep spare blades for your granulator. Downtime ain’t cheap in this business
PVC pipes jammed our last crusher so bad… learned our lesson about pre-sorting 🤦♂️
The torque protection feature saved our equipment thousands in repair bills last quarter!
Great overview! We’re starting small with PC-200 but that PC-1000 throughput is tempting 😍
Just bought a PC-200 last month after reading this! It’s been perfect for our small-scale PET bottle recycling operation.
