Plastic crusher, also called plastic crushing mill, is an indispensable plastic crushing and recycling equipment for plastic injection industry. It is mainly used to crush all kinds of hard and soft plastics, grinding the block-shape, spherical, flake-like, strip shaped plastics and plastic bottles, plastic shells, plastic crates and plastic bags into granular type for better recycling, vastly improving the utilization ratio of plastic products.
Superiority of Plastic Crusher
With the laddering rotating blades design, this plastic crusher has particularly strong crushing force and also has the elegant appearance. The anterior and posterior of this grinder’s cutting chamber is double layer sound proof, with acoustic insulating material filled in the middle part, resulting in very low noise. Moreover, it adopts reasonable knife type design to makes materials broken uniformly and adopts sealed bearings to keep good bearing rotation for a long period of time. Besides, the material of rotating blade holder is high-grade steel material, uneasy to abrade or break, making this waste plastic crusher durable and anti-corrosion cracking. Meanwhile, feed hopper of crusher uses optimization design and special rust-proof treatment, avoiding the materials leakage and pollution during the process of crushing. In a word, this plastic crushing mill has the advantages of stable operating performance, low noise, no powder pollution, uniform granulating, good grinding result and long service life, etc.
Working Principle of Plastic Crusher
During the working process of plastic crusher machine, its motor drives the high-speed revolution of rotating blade cutter head, and the high-speed rotating of rotating blade could form the relative movement trends cooperated with fixed blade. At the same time, utilizing the gap between rotating blade and fixed blade could give rise to cutting edges of plastic grinding and cutting, thereby crushing the large pieces of plastic. Finally, the broken plastics would be filtered and outputted according to particle sizes of plastic through the screen sieve.
Application Fields:
This waste plastic crusher machine is mainly used in plastics and aluminum plastic crushing business and recycling fields.
Maintenance of Plastic Crusher
- The plastic crusher should be installed in the ventilated position, ensuring the heat dissipation of motor working and prolonging its lifespan.
- Remember to add lubricating oil on bearings at regular intervals, ensuring lubricating property among bearings.
- Check the cutting tool and screw regularly and reinforce the fixity between blades and tool rest, fastening the screw of rotating blade and fixed blade after the bran-new plastic crusher machine working an hour.
- Clean the residual crushed materials in the machine before starting the equipment for the second time, reducing the starting resistance.
Watch the operating condition of plastic crusher all the time during the working process. First of all, feeding ought to be uniform, avoiding to block the crusher room; secondly, do not work overload for a long time. If there are phenomenon like vibration, noise, excess temperature of bearings and machine, materials spraying outward and so on, stop work immediately and identify the reason, and continue working after trouble clearing.
