The ultra-fine mill is one of the widely used equipment in the grinding processing industry. According to industry statistics, the share of ultra-fine 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 2 reasons for the reduction of the powder output of the ultra-fine mill and how to increase it.

Reasons For The Reduction Of The Powder Output Rate Of The Ultra-fine Mill

1. The separator does not work well

The separator of the ultra-fine 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 reground. In the case of severe abrasion of the blades of the separator, it will not play the role of classification, which will cause excessive powder extraction. Thick or thin, this situation can be solved by replacing the blade with a new one.

2. The fan is not adjusted properly

If the air volume of the fan of the ultra-fine mill is not adjusted properly or the air volume is too large, the powder output of the 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 condition is not abnormal, the air volume of the fan should be adjusted to correct the powder particle size.

How To Improve Flour Extraction Rate And Output?

Generally speaking, in order to making the ultra-fine mill produce large powder and high output, there are the following requirements:

1. Scientific and reasonable collocation

When the ultra-fine mill is working, on the one hand, it is necessary to consider whether the equipment model selection can meet the daily production requirements and avoid the equipment overload work; on the other hand, the material selection, try to choose the moderate hardness, which is more suitable for grinding to fine size to prevent excessive hardness material, which is difficult to realize the grinding operation, and is blocked in the discharge port, which causes 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 ultra-fine mill. Increase the running energy of the mill, adjust the belt or replace it with a new one.

3. Regular maintenance

After using for a period of time, the ultra-fine mill should be overhauled. At the same time, the wearing parts such as the grinding roller and grinding ring 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, The above is the most comprehensive technique and analysis of the reasons.
