6 Factors that affect the capacity of plastic grinder


Plastic grinders are machines that grind plastic materials into powder. They are widely used in the chemical industry, waste recycling, plastic pipe and profile manufacturing, and plastic modification.

The main components of a plastic grinder include a main unit, a grinding chamber, a grinding disc, and grinding tools. Inside the main unit, the motor drives the grinding chamber to rotate through the transmission device. The grinding disc and grinding tools in the grinding chamber also rotate accordingly. After the material enters the grinding chamber, it is crushed into powder by the impact and shearing action of the high-speed rotating grinding disc and grinding tools.

6 Factors that affect the capacity of plastic grinder

Plastic grinders come in a variety of types, such as rotor (turbo type) grinders and disc grinders. According to the grinding method, there are two types: ambient temperature grinders and deep cold grinders, of which ambient temperature grinders are the most common type.


The advantages of plastic grinders include compact structure, small footprint, all-steel integral structure, stable and durable, closed design, humanized knife adjustment, and convenient maintenance and cleaning. In addition, plastic grinders can grind various soft and hard leathers into fibrous form at ambient temperature, such as artificial leather, PVC, PE, and other materials with different molecular structures into 10-120 mesh powder, suitable for plastic modification and other fields.


The production capacity of a plastic pulverizer is affected by the following factors:

  1. Material moisture: The higher the moisture content of the material, the more likely it is to stick to the inside of the plastic grinder and block the discharge process, resulting in reduced grinding capacity. Therefore, the material should be dried before using the plastic grinder.
  2. Material hardness: The harder the material, the more difficult it is to grind, and the more serious the wear on the equipment. Therefore, for hard materials, a plastic grinder with good wear resistance should be selected.
  3. Material viscosity: The higher the viscosity of the material, the more likely it is to stick to the inside of the plastic grinder and affect the uniformity of grinding. Therefore, for materials with high viscosity, a plastic grinder with strong dispersion ability should be selected.
  4. Fineness of the material after grinding: The higher the fineness requirement, the smaller the grinding capacity. Therefore, the appropriate plastic grinder should be selected according to actual needs.
  5. Wear resistance of the grinding parts of the plastic grinder: The better the wear resistance, the larger the grinding capacity. Therefore, worn grinding parts should be replaced regularly.
  6. Power, speed, and grinding chamber volume of the plastic grinder: The larger the power, speed, and grinding chamber volume of the equipment, the larger the grinding capacity.

In addition to the above factors, the production capacity of a plastic grinder is also affected by other factors, such as the operating level of the operator and the maintenance of the equipment.
