effect of temperature in grinding in a ball mill

How Temperature Affect Grinding Efficiency

2017-10-24  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.

MnBi particles were prepared by grinding sintered MnBi in a ball mill. The coercivity of these MnBi particles was measured at 300 K and 85 K. At 300 K, the coercivity increased remarkably by grinding, and showed the highest value of 16000 Oe. At 85 K, the coercivity was very low compared with that at 300 K, and was about 80-400 Oe. For the particles which showed the coercivity of 16000 Oe at ...
