Grate Discharge Ball Mills have shown 25% to 45% more tonnage ground and a substantial reduction in power consumed per ton of material compared size for size with overflow mills. To illustrate the characteristics of various type mills we have shown the types of discharge for rod mills and ball mills. There are essentially four types of rod mill ...
Types of Mill Liners. There are several types of mill liners available, each with its unique properties and benefits. The most common types of mill liners include: Steel Liners. Steel mill liners are the most widely used type of mill liner, and they are typically made of highstrength steel alloys such as manganese steel, chrome steel, or Nihard.
Ball mills with two different sizes were considered in this study, one small and another large. The simulations with the two mills have the same conditions as the real ones by Valderrama et al. (1996) and Kalala and Moys (2004), respectively, in terms of mill size, particle size, mill speed fraction (mill speed as a fraction of critical speed) and fill level fraction.
