A Ball Mill. This one is easier - just a bit expensive. 1. Motor - 1750 rpm continuous duty 1/2 horse 2. Small pulley for motor 3. Larger pulley for drive shaft (the one in the picture is too large.. think a 5" or 6" would be better) 4. 6' of iron bar for roller shafts (I think these are 1/2")

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 kg/hr up to 25 TPH in a single mill.

Although the grinding capacity of ball mill varies with the operation system ( wet, dry, open and closed circuit ), size of feed material, size of products and quality of material, an example of over-flow type ball mill is shown in table below, together with major specification. Note : 1. Ball charge quantity is 40 % of mill inside volume. 2.

The time has come to re-think the approach to mill drive motors because of the growth in size of newer ball mills, the starting torque restrictions of some of the newer mill drive configurations, and the softness of some utility services. This paper looks at the serviceability and economics of five different mill motor options to meet these restraints. Some approaches are …
