Jun 29, 2020 For the feed material, the specific performance of a vibrating mill is 19.4 times higher than that of a ball mill and is 17.5 and 12.5 times higher in the classes of 125 and 74 m, respectively. Moreover, the coarser the size class, the more intensive its fracturing becomes in a vibrating mill, as compared to a ball mill.
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.
