When Raymond mill is grinding materials, sometimes the finished product particles are too coarse, too fine or uneven, which is also a situation that users often encounter. These are called abnormal powder discharge. How should we solve this situation? Xingaonai will take us to understand the solution to abnormal powder discharge of Raymond mill.

1. The powder lock is not sealed tightly
If the powder lock of Raymond mill is not sealed well during the grinding process, powder back suction will occur, resulting in no powder or less powder. Therefore, it is necessary to check the sealing degree of the powder lock and adjust it to an appropriate sealing degree.
2. The analyzer has no effect
The analyzer of the Raymond mill is responsible for analyzing the size of the finished powder and whether it meets the finished product standards. When the analyzer blades are severely worn, they cannot play a grading role, which will cause the powder to be too coarse or too fine. In this case, new analyzer blades need to be replaced.
3. The fan is not adjusted properly. If the air volume of the Raymond mill fan is not adjusted properly, the air volume is too large, which will also cause the mill to produce abnormal powder. The powder will be too coarse, and the air volume is too small, the powder will be too fine. When checking other conditions without abnormalities, the air volume of the fan should be adjusted to correct the powder particle size. 4. Blade failure. The blade of the Raymond mill is responsible for shoveling the material. If the blade is worn out or the quality is not strong enough, it will cause no powder or less powder. At this time, a new blade needs to be replaced to ensure the normal operation of the equipment.
