A roller ball mill is a relatively critical piece of basic equipment in the powder grinding and mixing process. Its working principle involves a main shaft connected to a motor, pulley, and bearings for transmission. Relative motion occurs between the main shaft and the tank, generating friction with the surface of the ball mill tank to drive another passive shaft for rolling. The entire roller shaft is externally lined with wear-resistant polyurethane sleeves to increase the friction coefficient and prevent tank deformation or slipping. Our company offers a complete range of roller ball mills with various specifications, organized into standardized and serialized product lines. The main product series include: dry grinding ball mills, wet grinding ball mills, lined ball mills, grinding and screening ball mills, laboratory ball mills, and various customized types.
