Ventilation effect in production is not good because of technological limitations. With the development of large scale ball mill, heat dissipation on per unit becomes less. High temperature in special season will affect the cooling effect of ball mill. These all cause the excessive internal temperature of ball mill in working process.

of the rings, balls, and cages from BluelBlack gold to blue. Temperatures in excess of 400°F can anneal the ring and ball materials. The resulting loss in hardness reduces the bearing capacity causing early failure. In extreme cases, balls and rings will deform. 'Ihe temperature rise can also degrade or destroy lubricant Common culprits are heavy

Within 20 seconds of entering the pellet mill, feed goes from an air-dry (about 10-12 percent moisture) condition at ambient temperature, to 15-16 percent moisture at 80-90°C. During subsequent compression and extrusion through holes in a ring' die, friction further increases feed temperature to nearly 92°C.

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball …

The temperature range is from 50°C to 12°C. It has been shown that in both plant and laboratory environments, the temperature of the grinding circuit slurry has a noticeable effect on grinding and cyclone efficiency. The d size of a hydrocyclone is function of temperature, and the relationship between them is linear.
