Raymond mill is one of the most widely used equipments in grinding industry. According to the statistics of the competent department of the industry, the share of Raymond Mill in the domestic grinding equipment is over 70%. But with the development of production, there will be a decrease in the powder capacity, which will affect the production efficiency. In this paper, four reasons for the reduction of the powder output of Raymond mill and how to improve the powder output are discussed.
If the sealing work of the powder lock is not done in place during the grinding process of Raymond mill, the phenomenon of powder suction will be formed, resulting in no or less powder. Therefore, checking the sealing of powder lock and adjust the sealing degree.
The analysis machine of Raymond mill is responsible for analyzing the size of the finished powder, whether it meets the finished product standard and does not need to be grinded again. In the case of severe wear of the blade of the analyzer, it cannot play the role of grading, which will cause too coarse or too fine powder. In this case, a new blade can solve the problem.
If the air volume of Raymond mill blower is not adjusted properly or the air volume is too large, it will also cause the abnormal powder output of the pulverizer, and the powder output will be too thick. If the air volume is too small, the powder will be too thin. In case of no abnormality in other conditions, the air volume of the blower shall be adjusted to correct the particle size of the powder.
The blade of Raymond mill is responsible for picking up the material. When the blade is used for a period of time or the quality is not good enough, the wear is large. If the material cannot be scooped up, the powder will not be discharged or less powder will be discharged. This requires the replacement of a new blade, so as to ensure the normal operation of the equipment.
Generally speaking, in order to make the production process of Raymond Mill produce large amount of powder and high output, there are the following requirements:
When the Raymond mill is working. On the one hand, it is necessary to consider whether the selection of equipment model can meet the daily production demand and avoid overload of equipment. On the other hand, in the selection of materials, try to choose the material with moderate hardness, which is more suitable for Raymond mill, so as to prevent the material from being too hard to achieve grinding operation and blocking at the discharge port, thus making it difficult to discharge the powder.
Considering the bearing capacity of the main motor is a factor to improve the production efficiency of the tilting mill. Increase the kinetic energy of the grinding mill, adjust the belt or replace it.
The Raymond mill should be overhauled after a period of use. At the same time, repair and replace vulnerable parts such as grinding roller, grinding ring and blade. The connecting bolts and nuts of the roller grinding device shall be carefully inspected before and after use. Checking whether there is looseness and whether the lubricating grease is fully added. In addition, when the roll grinding device is used for more than 500 hours to replace the roll, the rolling bearings in the roll sleeve must be cleaned and the damaged parts shall be replaced in time.
