How Temperature Affect Grinding Efficiency
In autogenous milling, temperature can significantly influence the grinding efficiency, particularly if the temperature falls below about 10°C. these efficiency changes can be reduced by preventing recycle water from becoming chilled, and by thawing frozen rock before grinding.

Grinding (abrasive cutting) - Wikipedia
Grinding is an abrasive machining process that uses a grinding wheel as the cutting tool.. A wide variety of machines are used for grinding: Hand-cranked knife-sharpening stones (grindstones)Handheld power tools such as angle grinders and die grinders; Various kinds of expensive industrial machine tools called grinding machines; Bench grinders
THERMAL DAMAGE IN GRINDING
Heat-producing grinding force and grinding power can he reduced by using sharp wheels, soft wheel grades, and frequent dressing (King and Hahn, 1986). Another method of controlling temperature is to employ Cubic Boron Nitride (CBN) wheels.
