vast majority of the electricity used by an electric motor drive system is consumed by the electric motor. Only a very small amount is used to power control functions or other ancillary circuits. Electric motors and the systems they drive are the single largest user of electricity, consuming more than twice as much as lighting.

An inching drive is used as an auxiliary system to the main drive for a large machine such as a ball mill, industrial kiln, conveyor, or elevator. Its purpose is to turn the equipment at a speed slower than the normal operating speed — typically 1 to 2 rpm, although fractional rpms are also common — and to do so at high torque — typically

If a ball mill uses water during grinding, it is a ‘wet’ mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills. Ball mills may be primary or secondary grinders.

Variable frequency drive for pumps Like fans, using a variable frequency drive (VFD) to control the flow rate from a pump rather than using simple throttle control can result in large power – and therefore cost savings. This is illustrated in following Figure, where the broken line indicates the power input to a fixed-speed motor and the solid line indicates the power input to a variable

And 1800 RPM for a ball mill is far out of control and i an runaway condition. As all ready commented, it is the starting torque that is the problem. My suggestion is an induction motor and a mechanically variable drive to start slowly and then go faster. Check out the reduction system on an older "HARTRIDGE" fuel injection pump tester.
