Ball mills characterized by high energy consumption. When the mill idles, the energy consumption is approximately equal to the energy consumption with full mill capacity. Therefore, the work of the mill with partial load conditions is unprofitable. Energy consumption for ball mills is a function of many factors: the physical properties of the ground material — its specific gravity and

GET PRICEThe ball mill can grind ores and other materials either wet or dry. There are two kinds of ball mill, grate type and overfall type, due to different ways of discharging material. Many types of grinding media are suitable for use in a ball mill, each material having its own specific properties and advantages. Key properties of grinding media are size, density, hardness, and composition.

GET PRICESimulation of wet ball milling of iron ore at Carajas Brazil. The analysis by Cho and Austin of a series of tests on open circuit wet ball milling of phosphate ore led to an equivalent classification of (21) s i = 1 1 (x 50 x i) 3.5. The controlling parameter is the particle sieve size x 50 at which 50 is returned to the mill feed and 50 exits the mill. Service Online; Cement millWikipedia

GET PRICEA Ball Mill Critical Speed (actually ball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shell's inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside a mill as speed varies. Use our online formula The mill speed is typically defined as the percent of the Theoretical
