[email protected]This type has low feed capacity and is rarely used in the metallurgical industry.Lifters and media.Lifters are used on the inside [periphery of the mill to:.It has been recognized that the grindability of an ore in a ball mill is a function of both feed and mill parameters: work.Mill power consumption example.Ball mill = 3.5 m x 3.5.
An empirical equation to estimate the maximum crushing capacity of hammer mills was obtained.The breakage characteristics of particles were characterized by the method to obtain the work index using a ball mill [4].Feed particles usedwere of the fraction between 2 and 1 mm screen opening.Figure 6.Example of relationship between the.
Read Morethe ball mill is used for grinding materials such as coal, pigments, and feldspar for pottery.Grinding can be carried out either wet or dry but the former is performed at low speed.Blending of explosives is an example of an application for rubber balls.
Read MoreAg/sag mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.Because of the range of mill sizes available, ag/sag milling can often be accomplished with fewer lines than in a conventional rod mill/ball mill circuit.A diagram of types of ag/sag.
Read MoreFurther tests were done, using samples from a platinum mine, namely the feed to a secondary mill (ball-mill) and rounded pebbles from a primary ag mill.Grinding capacity was maintained over the range 030% pebbles, by volume, with savings in energy and ball consumption increasing progressively.
