Ball mill. A typical type of fine grinder is the ball mill.A 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%.

On the S width method, small direct measurement differences cause big variations on the charge level estimatives and the trend of such errors is to increase in smaller diameter mills, which is the case of the measured ball mill. The MCP eliminates vague criterias adopted by people while measuring mill internally by common methods.

The optimal ball diameter in a mill 333 The grinding efficiency of the narrow particle size fractions with ball charge of various diameters has been observed through the constant of milling rate k in the equation of the grinding kinetics law for the first order grinding R=R 0

This Grindability Test or Bond Ball Mill Work Index Procedure is used to determine the Bond Work Index of minus six mesh or finer feed ore samples. These equation application methods are used to process <1/2″ ore samples in a Ball Mill using a standard ball charge. Below describes in general terms the Bond Work Index Procedure used by a Professional Metallurgical Testing Laboratory.

Zhang (2001) studied the fill level by measuring the energy consumption of the mill motor, but the wear of steel balls and the variation of ball load can seriously affect the power value of the mill. Kolacz (1997) proposed a method to measure the fill level by using a strain transducer. The transducer was installed at the middle of the mill shell.

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls.

maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between mill absorbed power and ball filling degree. As indicated on the graph, a small variation in power could be the result of a
