Nov 21, 2015nbsp018332In some mills e.g. hot strip mill, wire rod mill, merchant mill, and cold rolling mill, the rolled product is coiled in a coiler or a wind up reel. Mostly, rolling is done at high temperature, called hot rolling, because of requirement of large deformations. Hot rolling results in residual stress-free product.
The performance of tumbling mills is sensitive to the volumetric mill filling which influences grinding media wear rates, throughput, power draw, and product grind size from the circuit. Each of these performance parameters peaks at different filling values. In order to contin-uously optimize mill operation, it is vital to
