Motor Sizing Calculations. There are three factors to calculate when sizing a motor Moment of Inertia Torque and Speed. Moment of Inertia. Moment of inertia is the measure of an objects resistance to changes in its rotation rate. When an object is just sitting without any motion the moment of inertia is 0.
This design uses heavy duty support rollers to drive the rotation of the mill shell directly. Depending on the the drive and support rollers can be polyurethane lined rollers or a series of rubber tyres. Bulk Handling Techonolgies can design and supply roller mounted ball mills with capacities ranging from 500 kghr up to 25 TPH in a single mill.
