Ball mill operation is often regarded as something of a mystery for several reasons Ball milling is not an art it’s just physics The first problem will ball mills is that we cannot see what is occurring in the mill The other problem is that many of the independent variables are non linear or have paradoxical effects on the end resultsstructure of the mill There is very little capacity for large shock absorption so a failure of mill bearings normally the weakest link is typical Other costly types of damage that occur from falling charge although less frequent are cracks in the mill heads and shells LOCKED CHARGE STARTS AND YOUR GRINDING MILL Authors Jeff Belke
