Reason of Quicklime Grinding Mill Low Output Rate and How to Deal with That?

The 400 mesh quicklime grinding mill is one of the widely used equipment in the grinding and processing industry. According to the statistics of the competent department of the industry, the share of 400 mesh quicklime 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 4 reasons for the reduction of the powder yield of the quicklime grinding mill and how to increase the powder yield.

Reasons of Quicklime Grinding Mill has Low output rate

1. The powder locker is not tightly sealed
If the 400 mesh quicklime grinding mill is not in place during the grinding process, the powder locker seal is not in place, it will cause powder suction phenomenon, resulting in no powder or less powder, so check the seal of the powder locker and adjust Degree of sealing.
2. The analysis machine is not working
The analyzer of the 400 mesh quicklime 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 and will cause powder Too thick or too thin, this situation can be solved by replacing a new blade.
3. The fan is not adjusted properly
If the air volume of the 400 mesh quicklime grinding mill fan is not adjusted properly, the air volume is too large, the powder output of the mill will be abnormal, the powder output will be too thick, the air volume is too small, the powder output will be too fine, check other conditions If there is no abnormality, the air volume of the fan should be adjusted to correct the powder particle size.
4. The blade is malfunctioning
The shovel blade of the quicklime grinding mill is responsible for shoveling up the material. When the shovel 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. A new blade needs to be replaced to ensure the normal operation of the equipment.

How to Improve Quicklime Grinding Mill Rate&Output

Generally speaking, in order to make the 400 mesh quicklime grinding mill produce a large amount of powder and a high output, the following requirements are required:
1. Scientific and reasonable collocation
When the 400 mesh quicklime grinding mill is working, on the one hand, it is necessary to consider whether the selection of the 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 a moderate hardness as much as possible. The 400 mesh quicklime mill material prevents excessive hardness of the material, which is difficult to realize the grinding operation, and it 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 host motor is a factor to improve the production efficiency of the suspension roller mill. Increase the running energy of the mill, adjust the belt or replace it with a new one.
3. Regular maintenance
The 400 mesh quicklime grinding mill should be overhauled after being used for a period of time. At the same time, the wearing parts such as the grinding roller, 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 are any Loose phenomenon, whether the lubricating grease has been added enough, and when the grinding roller is used for more than 500 hours to replace the grinding roller, the rolling bearings in the roller sleeve need to be cleaned, and the damaged parts should be replaced in time.
