Q1:Is the operation of the pulverizer complicated?

A1:As long as the operating procedures are followed, the operation of the pulverizer is not complicated. Before starting up, it is necessary to conduct a comprehensive inspection of all components of the equipment, such as motors, blades, screens, feed ports, etc., to ensure that there are no abnormal situations; After startup, the feeding amount and speed should be controlled according to the material characteristics and grinding requirements to avoid equipment failure caused by excessive or rapid feeding; After shutdown, it is necessary to promptly clean the residual materials inside and on the surface of the equipment to prevent material accumulation from affecting the next use. For operators who are using the pulverizer for the first time, it is recommended to receive specialized training to familiarize themselves with the equipment’s operating procedures, the functions of the control panel, and common troubleshooting methods. In the actual operation process, through continuous practice and summarizing experience, one can operate the pulverizer more proficiently.

Q2:What are the requirements for the feed particle size of the pulverizer?

A2：The pulverizer has strict requirements for the feed particle size, generally not exceeding the maximum feed particle size specified by the equipment. Different models of pulverizer have different maximum feed particle sizes, usually less than 15MM. If the particle size of the feed is too large, it is easy to cause blockage at the feed inlet, making it difficult for the material to enter the grinding chamber smoothly; Even if entering the grinding chamber, it will increase the load on the blades and grinding components, causing equipment failure and affecting the grinding effect and equipment service life. Therefore, before feeding, it is necessary to preprocess the material and crush it to the appropriate particle size range to ensure that the mill can work properly.

Q3:How long does it take to replace the blades of the pulverizer?

A3:The replacement cycle of blades mainly depends on the frequency of use and the hardness of the material. If the grinding machine is frequently used and works for a long time every day, the friction between the blade and the material increases, and the wear rate accelerates; The greater the hardness of the material, the more severe the wear on the blade. For example, in the case of frequent handling of hard plastics, the blade may need to be replaced within one to two months; If the frequency of use is low and soft plastic is being processed, it can be replaced every six months or so. In addition, it is also possible to determine whether the blade needs to be replaced by observing the grinding effect. If the grinding efficiency significantly decreases, the powder produced is uneven, or abnormal sounds are heard when the blade cuts materials, these may indicate that the blade has been severely worn and needs to be replaced in a timely manner.

Q4:How to choose the screen of the pulverizer?

A4:We need to consider multiple aspects when choosing the screen of the pulverizer.
Firstly, there are materials commonly used, such as stainless steel and manganese steel. Stainless steel mesh has good wear resistance and is suitable for the grinding process of most plastics; Manganese steel mesh has strong impact resistance, and when dealing with materials with high hardness or impurities, manganese steel mesh will be more durable.
Next is the aperture, we need to choose the appropriate aperture based on the target fineness, such as 30 mesh, 80 mesh, etc. The size of the aperture directly determines the fineness of the powder, so it should be selected according to specific production needs.
In addition, the shape of the screen mesh also varies. The circular hole screen mesh can screen out relatively uniform powder, which is suitable for production with high requirements for powder uniformity; The sieve with strip holes has a higher yield and is suitable for handling large amounts of materials.

Q5:What are the vulnerable parts of the pulverizer?

A5:The vulnerable parts of the pulverizer mainly include blades, screens, bearings, seals, etc. During the high-speed rotation of cutting materials, the blade will continuously experience wear and tear, resulting in a decrease in cutting ability; The sieve mesh is prone to deformation and damage due to long-term friction with the material; Bearings bear significant loads and frictional forces during equipment operation, which can lead to issues such as wear and fatigue; Seals will lose their sealing performance due to aging and wear. These vulnerable parts need to be inspected regularly and replaced in a timely manner based on actual wear and tear to ensure the normal operation of the pulverizer.
