A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about
It is possible to make an approximate calculation of the capacity of a ball mill by means of the equation: N = ( D 3 L b .ap 0 .88 + L n ) 1 1 2 where is the apparent density of the balls; l is the degree of filling of the mill by balls; n is revolutions per minute; 1, and 2 are coefficients of efficiency of electric engine and drive, respectively.

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.
#0183;#32;With a better grasp on the theories behind highperformance media mills, the process of determining the best media mill for your application will not be so painful. There are also questions you can ask an equipment supplier on the practical functions of the mill to judge the maintenance and operator friendliness of the unit for further differentiation.
The sizing of ball mills and ball milling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience. Different manufacturers use different methods, and it is difficult to check the validity of the sizing estimates when estimates from different sources are widely divergent. It is especially difficult to teach mill
#0183;#32;Summary The Ball Mill is designed to grind materials by turning the cylindrical shell with grinding medium ( steel balls) put in the shell, and has a simple structure and ease of handling. Furthermore, The Ball Mill of a large capacity has been available to a very extensive range of applications in both dry and wet 14.

Ball mill. A typical type of fine grinder is the ball slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.
