- Ball Mill Grinding And Particle Size Distribution

Ball Size Distribution. As the mill starts, grinding action and throughput increases. However, after reaching a critical speed, the mill charge clings to the inside perimeter of the mill. Under this conditions, the grinding rate is significant reduced or stopped. All mills must operate less than Critical Speed

Our crushers are designed and built with advanced technology and stringent quality control at every stage of the manufacturing process, to meet the rigorous demands of aggregate operations.Our #1 goal is making the customer more productive and profitable by providing the best impactor-based technology and after-market support available.

The mill (with 30 cm in diameter and 30 cm in length) and the test conditions are standardized, with a maximum ball size of 40 mm and an ore top size of 3.35 mm. With less than 300 balls, it poses no challenge in running the simulations, if only grinding media are included. For such a small mill, one could also include the ore or powder charge.
