Various ball mill machines, vertical roller mills and sag mills are widely used in the mining industry. Grate ball mills and raw mills are mostly used for mineral processing in some enterprises of mining industries. Wet ball mill and rod mill are commonly used in mineral processing production line, to grind various hardness ore materials.

The discharge grates of the SAG mill were identified as a key component in the SABC circuit, and their design is a crucial factor in the mill's performance [17,18,19,20,21]. The initial design of the grate section caused a serious accumulation of pebbles within the SAG mill which contributed to a decreased grinding efficiency.

Your problem can occur in a SAG Mill or Ball Mill. Other point to consider is the particle size distribution, it is possible to receive a finer ore from the mine and the particle size distribution of the product from the crushing circuit is different, In this case, the residence time in the tumbling mill tend to be shorter.
