Common problems and solutions of Raymond mill

Raymond mill is the main grinding equipment for processing limestone, lime, calcium carbonate, gypsum powder, etc. It is widely used, and some problems are inevitable in daily use. Today, I will summarize the common problems and solutions of Raymond mill in daily use.

Q1: Raymond mill produces less powder

The main reason is that the powder lock is not tightly sealed. During the grinding process, if the powder lock is not properly sealed, the phenomenon of powder sucking will be formed. This will cause no powder or less powder, so check the seal of the powder locker and adjust the degree of sealing.

Q2: The powder is too coarse or too fine

This is where the analyzer doesn’t work. The role of the analyzer is to analyze the size of the finished powder. It judges whether the powder meets the finished product standard and needs to be sanded again. In the case of serious wear of the blades of the analyzer, the effect of classification cannot be achieved, which will cause the powder to be too coarse or too fine. In this case, replacing a new blade can solve it.

Q3: The powder particle size is abnormal

This may be due to the Raymond mill fan is not adjusted properly. If the air volume of the fan of the Raymond mill is not adjusted properly, it will also cause the powder output of the mill to be abnormal. If the air volume is too large, the powder will be too thick. If the air volume is too small, the powder will be too fine.

Q4: Powder leakage at the bottom of the mill

Raymond mill

There is a gap between the main frame and the edge of the grinding disc. It can be solved by designing a recycling return device or a blocking leakage device. It is also possible to extend the distance between the outer edge of the material bed and the outer edge of the grinding disc, or add a baffle with a certain height.

Q5: The fan of Raymond mill is vibrating too much

This may be caused by powder buildup on the blades or uneven wear. Sometimes the loose anchor bolts will also cause the fan to vibrate too much. Usually, we can make adjustments by removing the powder accumulation on the blades or replacing the blades and tightening the anchor bolts.

In addition to these common problems, we also need to pay attention to some matters in the process of using Raymond mill. In this way, the failure of Raymond can be reduced, and the specific methods are as follows:

Ensure normal working load and refuse to overload work.

Reasonable lubrication. The appropriate lubricant category should be selected according to the type of Raymond mill and application structure.

Regular inspection and maintenance. It is necessary to keep abreast of the operation of the machine through regular inspection and maintenance. Temporary failures should be dealt with in a timely manner.

It is very important for our production to ensure the normal operation of the Raymond mill and the stability of the output. Therefore, we need to pay attention to the daily maintenance and use of Raymond mill. If you have any problem, please contact us Daswell. It’s glad to serve you.
