The segmentation of grinding and milling systems. Module 2 – Ball mills. This module will cover the technology of ball mills used for raw and finish grinding in the cement manufacturing process. Mechanical description of the different types of mills. Ball mill grinding equations and dimensioning. Mill internals, media, liners and.Planetary ball mill is a most frequently used system for mechanical alloying since only a very small amount of powder is required. Therefore, the system is particularly suitable for research purpose in the laboratory. The ball mill system consists of one turn disc (turn table) and two or four bowls.
Apr 24, 2015 2. Ball mill consist of a hollow cylindrical shell rotating about its axis. Axis of the shell horizontal or at small angle to the horizontal It is partially filled with balls made up of Steel,Stainless steel or rubber Inner surface of the shell is lined with abrasion resistant materials such as Manganese,Steel or rubber Length of the mill is.Performance equation (McIvor et al., 1990), the absence of a performance parameter to isolate ball mill grinding efficiency handicapped efforts to study the effect of any ball mill design or operating variable. Along with plant testing difficulties, only fairly large changes in circuit performance could be linked to a media size change.
