The HGM stone powder grinding mill is one of the widely used equipment in the grinding processing industry. According to industry statistics, the share of stone powder grinding mill in domestic grinding equipment is as high as 70%. However, as the production progresses, the powder extraction rate will decrease, which will affect the production efficiency. This article shares 3 reasons for the reduction of the powder yield of the stone powder grinding mill and how to increase the powder yield.
1. The analysis machine is not working
The analyzer of the stone powder grinding mill is responsible for analyzing the size of the finished powder, whether it meets the standard of the finished product, and does not need to be sanded again. When the blade of the analyzer is severely worn, it will not play the role of classification, which will cause excessive powder Thick or thin, this situation can be solved by replacing a new blade.
2. The fan is not adjusted properly
If the air volume of the fan of the stone powder grinding mill is not adjusted properly, or the air volume is too large, the powder output of the grinding mill will be abnormal, and the powder output will be too thick. If the air volume is too small, the powder output will be too fine. Check other conditions. Under abnormal conditions, the air volume of the fan should be adjusted to correct the powder particle size.
3. The blade is malfunctioning
The blade of the stone powder grinding mill is responsible for shoveling the material. When the blade is used for a period of time or the quality is not good enough, the wear is large, the material cannot be shoveled, and it will cause no powder or less powder. This requires replacement of a new blade to ensure the normal operation of the equipment.
Generally speaking, in order to make the stone powder grinding mill produce large powder output and high output, the following requirements are required:
1. Scientific and reasonable collocation
When the stone powder grinding mill is working, on the one hand, it is necessary to consider whether the selection of equipment model can meet the daily production requirements and avoid overloading work of the equipment; on the other hand, when selecting materials, try to choose moderate hardness as much as possible, which is more suitable for super The material of the pulverizer is fine to prevent excessive hardness of the material, which is difficult to realize the grinding operation, and is blocked at the discharge port, causing difficulty in discharging powder.
2. Reasonably choose the main engine speed and improve the main engine grinding force
Considering the carrying capacity of the main engine motor is a factor to improve the production efficiency of the pendulum stone powder grinding mill. Increase the kinetic energy of the stone powder grinding mill, adjust the belt or replace it with a new one.
3. Regular maintenance
After using for a period of time, the stone powder grinding mill should be overhauled. At the same time, the wearing parts such as the grinding roller, grinding ring, blade, etc. should be overhauled and replaced. The connecting bolts and nuts of the grinding roller device should be carefully checked before and after use to see if there is any looseness. Phenomenon, whether the lubricating grease is sufficient, and when the grinding roller device is used for more than 500 hours to replace the grinding roller, the rolling bearings in the roller sleeve must be cleaned, and the damaged parts should be replaced in time.
