The disadvantages of ball mills include their considerable metal consumption and deterioration grinding media, as well as a lot of noise. Most of the energy useless lost during ball mill operation, leading to low it efficiency. But even a significant specific energy consumption for grinding material compensates beneficial effect by using mill.

Large roll ball mill is a kind of equipment used for ultra fine grinding and mixing for batch production, which is also called rolling machine altar. The machine is preferred equipment for scientific research, teaching, experiment and production due to its advantages such as beautiful design, compact structure, easy operation, high efficiency, and uniform granularity.
Rod Mills are usually operated in open circuit. Most rod mill applications involve wet grinding where material is reduced in size from crusher product size to a size suitable for ball mill feed. To avoid breakage or tangling of rods, the L/D ratio of rod mills is kept within the limits of 1, 3/1 to 2/1.
Keywords Ball mills, grinding circuit, process control. I. Introduction Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical, mechanical and chemical characteristics. Typical examples are the various ores, minerals, limestone, etc.
Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6.
