Detailed Introduction

Vertical mill is one of the most widely used equipment in the milling industry. According to statistics from the competent department of the industry, the share of lm vertical mills in domestic milling equipment is over 70%. However, with the progress of production, if the lm vertical mill is in the milling process, the sealing of the powder lock is not done properly, it will cause the phenomenon of powder back suction, resulting in no or no powder, so check the lock. Powder seal, adjust the degree of seal. This article shares the four reasons for the reduction of the powder output rate of the lm vertical mill and how to improve the powder output rate.

Causes Of Lower Output Rate Of LM Vertical Mill

1.The powder lock is not tightly sealed

If the lm vertical mill is in the milling process, the sealing of the powder locker is not in place, it will cause the powder to suck back, causing no powder or less powder, so check the seal of the powder locker and adjust the seal. degree.

2.The analysis machine is not working

The analyzer of the lm vertical mill is responsible for analyzing the size of the finished powder, whether it meets the standard of the finished product, and whether it needs to be sanded again. In the case of severe abrasion of the blade of the analyzer, it can not play the role of classification, which will cause powder Too thick or too thin, this situation can be solved by replacing with a new blade.

3.The fan is not adjusted well

If the air volume of the lm vertical mill fan is not adjusted properly, if 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 will be too small, and the powder output will be too fine. There is no abnormality in checking other conditions In the case of airflow, the air volume of the fan should be adjusted to correct the powder particle size.

4.Blade failure

The blade of the vertical mill is responsible for scooping up the material. When the blade is used for a period of time or the quality is not strong enough, the wear is large and the material cannot be shoveled. This requires replacing the blade with a new one to keep the equipment running.

How to improve the output rate and output of vertical mill

Generally speaking, in order to make the lm vertical mill produce a large amount of powder and high output, the following requirements are required:

1.Scientific and reasonable matching

When working with the lm vertical mill, on the one hand, it must be considered whether the selection of the equipment model can meet the daily production requirements and avoid overloading the equipment; on the other hand, when selecting materials, try to choose a moderate hardness, which is more suitable. The material of lm vertical mill prevents the hardness of the material from being too large, it is difficult to achieve the milling operation, and it is blocked at the discharge port, which makes it difficult to discharge the powder.

2.Reasonably select the main engine speed and increase the grinding power of the main engine

Considering the bearing capacity of the host motor is a factor to improve the production efficiency of the swing mill. Increase the kinetic energy of the mill, adjust the belt or replace it with a new one.

3. Regular maintenance

After using the lm vertical mill for a period of time, it should be overhauled. At the same time, it should be overhauled and replaced the wearing parts such as the grinding ring blade. The grinding device should carefully check the connecting bolts and nuts before and after use. Looseness, whether the grease is full, and when the roller device is used for more than 500 hours, the roller bearings in the roller sleeve must be cleaned and the damaged parts should be replaced in time.
