Operation and Elements of a Closed Circuit Ball Mill System. Cement ball mills typically have two grinding chambers. The first chamber is filled with larger diameter grinding media and lined with lifting liners. The first chamber coarse-grinds the feed material and prepares it for the second chamber. The second chamber is the fine grinding chamber.

The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and non-ferrous metals. The ball mill can grind various ores and other materials either wet or dry.

Jul 07, 2017 · In a pin mill, the particle size is controlled by three parameters: Feed rate, rotor speed and airflow. Varying these parameters will have the following effects: Increasing the feed rate will result in a coarser particle size while reducing the feed rate will have the opposite effect.

Mine-to-mill optimisation: effect of feed size on mill throughput No. 48 SRK Consulting's International Newsletter One of the most valuable aspects of blasting is the generation of very fine particles (e.g., smaller than 12mm) that will pass through the primary mills and onto the secondary ball mill circuits, alleviating a common bottleneck.

The capacities, power requirements, etc., of the various sizes of Marcy Ball Mills are given in Table 11.
