Introduction of Waste Plastic Crusher
A plastic waste shredder machine is a recycling equipment that specializes in crushing waste materials into pieces, which is widely used in the industries of plastic recycling, regeneration and granulation, waste products processing, and environmental protection resource utilization.
It crushes scraps by cutting and shredding them into small flakes through the high-speed rotating blades. This step is convenient for subsequent cleaning, melting, extruding, and pelletizing.
破碎机是破碎机中的重要设备 塑料颗粒生产线。


Plastic Crushing Machine Principle
塑料回收碎片机的工作原理是移动刀片在高速旋转的同时与固定刀片合作切割大块塑料。然后,物料通过筛网过滤并输出。


Structure of Shredder Machine
塑料碎片机主要由进料斗、破碎室、刀架、筛板、下料斗、电机等组成。 塑料碎片机 。
破碎机的破碎腔是物料被破碎的场所。破碎室内有动刀片、定刀片、筛网等附件。



Plastic Grinding Machine Application
Industrial grinder machine can crush HDPE, LDPE, LLDPE, 宠物, PVC, ABS, etc., like buckets, baskets, trays, straws, irrigation pipes, auto bumpers, 电影, shopping bags, woven bags, electronic meters, bubble wrap, cosmetic tubes, bag cut-offs, agricultural films and other plastic scraps.
破碎的颗粒可以直接用作制粒的原料。

Waste Plastic Crusher Working Process
Step 1:Feeding
The waste plastics (such as bottles, films, woven bags, pipes, etc.) are fed into the crushing chamber of the waste plastic crusher through the inlet or conveyor belt. Some models are equipped with a pressure device to prevent the material from rebounding.
Step 2:Crushing
The crushing chamber of the waste plastic crusher is equipped with a set of rotating knives (movable knives) and fixed knives. When the plastic enters the area of the blades, a strong shearing and tearing effect is formed between the movable knife and the fixed knife, thus breaking the plastic material into small pieces.
- The movable knife rotates with the knife shaft at high speed.
- The fixed knife is fixed in the knife frame or side wall.
Step 3:Sizing
The crushed material falls to the screen structure (sieve plate) at the bottom of the machine, and only the crushed material with a particle size smaller than the sieve hole can pass through.
- Only material with a particle size smaller than the holes in the sieve passes through. Material with a particle size too large for the sieve continues to be crushed.
- The screen can be replaced to control the size of the material to be discharged.
Notes on Waste Plastic Crusher Shredder Machine
- Regularly check the bearings and replace the high-speed grease to ensure the normal operation of the industrial shredder.
- After work, the shredder machine must be cleaned of all parts of residual materials.
- 破碎机在使用时,如发现主轴转速逐渐降低,必须下调电机,使机器达到规定转速,发现异常应停车检查。
- 开启时严禁将金属物料进入机器,例如钉子、铁等。 塑料破碎机 开机后,严禁钉子、铁块等金属材料流入机器内。
- 进料应逐渐增加物料流量,并持续观察电机功耗和运行情况。

FAQs of Plastic Shredder Machine for Recycling
How does a plastic shredder machine for the recycling process of plastic bottles, films, and woven bags?
Plastic bottles, films, and woven bags can be fed directly into the shredder machine, where the machine’s blades will cut them into smaller particles or fragments by shearing. For larger or harder materials, pre-processing is recommended (e.g. foam compressor).
What size materials can the Waste plastic crusher handle?
Different models of Waste plastic crushers can handle different sizes of materials. Generally speaking, the inlet size, blade design, and power of the machine will affect the processing capacity. You need to choose the right model according to the actual demand.
How often do I need to change the blades of my plastic shredder?
The frequency of blade replacement depends on the usage, the hardness of the material being processed and the blade material. In general, if the blades are worn or not sharp, they should be replaced promptly.
