The particle size distribution of ball mill grinding products is an important production index of the grinding operation, and due to its multivariate strong coupling and nonlinearity in the operation process, it leads to difficulties in achieving optimal control of the discharge particle size distribution. To this end, a reinforcement learning-based optimal control method is …

Wet ball mill as the most important machine of ore beneficiation field, the performance of ball mill determines the whole producing plant quality. The common wet ball mill are …

 — Typically in wet overflow grinding mills the product is allowed to exit the mill by overflowing the discharge trunnion. The driving force for flow of slurry from the feed to discharge end of the mill is the flow gradient due to the discharge trunnion being larger than the feed trunnion. However, grate discharge mills have a more complex mechanism.

 — Grated / Diaphragm Ball Mill: Designed to discharge material through slots or grates, providing efficient grinding and separation. Peripheral Discharge Ball Mill: This mill features discharge ports around its periphery, allowing quick removal of the ground material.
