A series of tests were performed in a laboratory ball mill using (i) three loads of single size media, i.e., 40, 25.4, and 12.7 mm and (ii) a mixed load of balls with …
Reason: This is a common problem mining ball mills face, resulting in low productivity and low ore processing efficiency. One reason may be the improper design of the grinding chamber, which affects the flow of materials and reduces grinding efficiency. Additionally, worn or damaged liners can hinder the grinding process by reducing the …
Wet disc mills generally have simpler mechanical structures and fewer moving parts than traditional ball mills, which can mean lower downtime and operating costs. 3. Abrasiveness. Harder materials may wear out the ball mill more quickly than a sturdier designed wet disc mill, requiring more frequent grinding media changes.
