China Hualan plastic shredder processes large-volume, irregular waste plastics (such as car bumpers, plastic pallets, pipes, and films) into uniformly sized fragments through shearing, tearing, and crushing.
Plastic shredder can be divided in to double shaft shredder, single shaft shredder and four shaft shredder
Double plastic shaft Shredder
Single plastic shaft Shredder
First, waste materials are fed into the chamber by gravity or a hydraulic pusher. Inside, the motor-driven rotor creates immense shearing force—acting like heavy-duty scissors—to tear the plastic apart. Finally, a bottom screen ensures quality control: only particles small enough pass through, while larger pieces are retained for re-shredding until they meet specifications.
By Material:
Bulky/Hard Materials:
include car bumpers, plastic pipes, purgings (lumps), home appliance housings, and PC/ABS engineering plastics;
Thin/Soft Materials:
cover waste film, woven bags, agricultural film shredders, and PET bottle crushing & washing lines.
By Industry:
Applications include domestic waste, e-waste (such as circuit boards and transformers), industrial solid waste, and medical waste destruction, among others.
For Soft Plastics (Film / Woven Bags)
Suggested Materials: 9CrSi or 55CrSi
(Note: These alloy tool steels offer a good balance of toughness and hardness, suitable for cutting fibrous and flexible materials.)
For Hard Plastics (ABS / PC / Pipes)
Suggested Materials: Cr12MoV, etc.
(Note: High-carbon, high-chromium cold work die steel known for excellent wear resistance against abrasive rigid plastics.)
For Impure Materials (Plastics with Metal / E-waste)
Suggested Materials: H11, etc.
(Note: Hot work die steel selected for its superior impact toughness to withstand shocks from contaminants like iron or copper.)
Single shaft plastic shredder
| Name | Single shaft plastic shredder |
| Suitable Material | Difficult-to-cut thick-walled pipes, solid lumps, and films. |
| Output Size | Precise (Equipped with bottom screens for strict size control) |
| Anti-winding | Weak (Requires hydraulic ram feeders to prevent film winding) |
| Application | Fine crushing, directly interfacing with washing/granulating lines |
Double shaft plastic shredder
| Name | Double shaft plastic shredder |
| Suitable Material | Bulky waste, mixed waste, and impurity-laden materials |
| Output Size | Coarse (No screen; irregular output size, strip/block shape) |
| Anti-winding | Extremely strong (Utilizes high torque to automatically tear |
| Application | Coarse crushing for volume reduction;primary shredding . |
