What should I do if the temperature of the sand mill is too high when grinding materials?

2021-11-11

1. Is the cooling water supply of the Sand Mill sufficient? There is no pressure in the cooling water outlet of the sand mill, and the flow rate is small, etc., which may be caused by insufficient cooling water supply.
2. Is the cooling water temperature of the sand mill ≤10℃? Recommended cooling water for sand mill ≤10℃
3. Are there too many grinding beads in the sand mill? Without affecting the efficiency of grinding materials, appropriately reduce grinding beads.
4. Are the raw materials excellent? If the raw material is too hard, the kinetic energy of the grinding beads will be greater when the polymer is opened, and the temperature will rise accordingly.
5. Is the discharge flow of the sand mill too large? When the discharge flow rate of the sand mill is too large, the feed pressure will increase. At this time, the grinding beads will be densely piled at the discharge end, forming a local high temperature, which affects the temperature of the material. At this time, the discharge flow rate should be appropriately reduced.
6. Is the ambient temperature of the production site high? During summer production, the temperature of the material to be ground by the sand mill is higher than that in winter.
7. Is the amount of materials too small? Different sand mill models have different production capacities and different batching quantities. If the material to be ground is too small, the first grinding will have a high temperature, and the second grinding will continue to increase the temperature. In this case, it is usually recommended to match the appropriate amount of material, and use two pull cylinders, one in and one out, to be installed separately, which will help the material to dissipate itself after being discharged from the sand mill. Customers with good conditions can also use the material pulling cylinder with cooling water circulation.
