Our standard heavy-duty plastic granulator machines, sometimes called plastic crushers, are essential machines in the plastic recycling industry. These specially designed granulators are extremely durable and have the unique ability to quickly and efficiently cut various plastic streams into small uniform flakes or regrinds.

As one of our most sold types of plastic recycling machine, these granulators are packaged in many of our complete recycling solutions including our popular PET bottle washing lines, plastic film recycling lines, and more.

Working Principle of Plastic Granulator

At the core of our plastic granulator machine is an open rotor mounted with heavy-duty knives in either a double-scissor cut or v-shape array based on your requirements. As the rotor is spun at high speeds, the rotor knives come in contact with stationary knives that are mounted within the cutting chamber. The material is continuously cut until they are small enough to pass through a screen filter.


Generally speaking, our filter screens are between 10mm to 100mm but can be customized according to your requirements.


Our standard plastic granulator houses 12 rotors and 3 stationary knives. All knives use only ultra-durable D2 (equivalent to SDK11) high-carbon, high-chromium steel which ensures the longest usage times before requiring sharpening. All knives are easily adjustable with hydraulic assisted access to the cutting chamber.



Plastic Granulator Applications:

This general-purpose plastic granulator can be used in a variety of applications for plastic recycling including but not limited to grinding plastic bottles, films, and a variety of small rigid plastics.

For added convenience, we also offer wet plastic granulator machines that have additional rubber sealing and water inlet hose attached allowing a constant stream of water to be sprayed while the plastic is being cut. This helps clean the plastic scrap while keeping the blades cool during operation.


Basic Maintenance Of Plastic Granulator:

The following areas are very essential when maintaining this powerful plastic granulator machine:

 

1. Bearing

Bearing is a vital component in the plastic crusher. There should be frequent lubrication of the bearing. It will enable it to roll easily without any obstruction. If there is no proper maintenance, rust will cause it to become stiff.

While it is very important to lubricate the bearing, it is advisable not to apply excessive lubricating substances to avoid damage to the bearing.

 

2. Maintenance Of The edge and blade

To ensure that the edges are sharp, it is important to regularly sharpen it appropriately. It is a good way to avoid damage to the tools. Moreover, when the edge is blunt it will require more force for the crusher to break large stones.

Furthermore, sharpen the blade to avoid it becoming blunt. It is a good way to maintain the blade for effective use. The angle of the blade should be consistent with the originating angle to accomplish a good shearing function. 


3. Change Of Cutter and Screen

In a situation where the cutter of a plastic crusher needs replacement, the person that will replace the cutter should give proper attention to the clearance between the fixed cutter and the moving cutter.

For the screen, check the pull button to know if it is tight or not. If it is not tight, use the screw to tighten it to the button bracket.

 

4. Position Of The Machine

It is ideal for the machine to balance at the base. Position the crusher well on level ground. It will allow the machine to work seamlessly without any obstructions.

Wrong position can affect the productivity of the machine. So, it is essential to take the right steps before operating it.

 

5. Routine Maintenance

The following checks should take place every day:

a. Before starting the machine, check the power supply to ensure that the voltage supply is sufficient for operation.

b. Be careful of what you crush because there are materials that can quickly damage the crusher.

c. Check the fan and the crushing chamber to be sure there are no foreign materials before operating the machine.

d. Lubricate areas that require routine lubrication

e. When you finish the crushing process, stop the machine and clean all of them.

f. In case of any strange noise, quickly off the machine and call professionals to check it.
