2020-1-26Very nice mill. Who makes it. My Williams book stone mill, wooden frame has 12 inch stones, 4-5 hp, 1000rpm 16 inch stones, 6-8hp, 800 rpm 20 inch stones, 8-10 hp, 700 rpm those are production numbers, i dont think it would make any difference to run slower, unless the mill would have problems throwing out the flour at slower speeds.

For the mining industry, our semi-autogenous SAG grinding mill uses a minimal ball charge in the range of 6-15 percent. It is primarily used in the gold, copper and platinum industries as well as in the lead, zinc, silver, and nickel industries. Autogenous AG grinding mills involve no grinding media as the ore itself acts as the grinding media.
2012-7-10Grinding in ball mills is an important technological process applied to reduce the ... depending on the type of the mill, the operating conditions and the type of the material being ground. Several basic concepts are commonly used in modeling of the grinding process. The starting material naturally consists of particles which differ
