AG/SAG mills can accomplish the same size reduction work as two or stages of crushing and screening a rod mill and some or all of the work done by a ball mill. All because of the range of mill sizes available AG/SAG milling extends itself to many applications.
Ball mills and rod mills are grinding equipment widely used in concentrators. The two have similarities in shape and grinding principles but there are differences in structure performance and use. This article analyzes their similarities and differences from seven aspects and tells you how to choose ball mill and rod mill!
Comparison between Rod Mill and Ball Mill. 20140103. Rod mill is a type of grinding mill whose grinding media is steel bar while ball mill is steel ball. 1. Rod mill are usually applied to grinding the wsn ore and rare metal in the reselection or magneticoredressing plant in order to avoid the damage caused by the over crushing.
Ball mills and rod mills are both excellent mining machines for grinding ores into fine powders and particles. However there are some advantages to using rod mills rather than ball mills for larger mining projects including greater efficiency better grinding performance and lower energy costs.
No 1 rod mill/ball mill circuit was operating very efﬁ ciently when comparing the combined operating work indices for both mills with the rod mill and ball mill laboratory work indices. Note in Figure. 1 that the rod mill product slope is less than 0.5 due to an extra amount of
Apr 09 2015nbsp018332Ball mills. Ball mill (Fig 1) is same kind of mill as rod mill except that it is filled with balls instead of rods. Because of balls have greater ratio of surface area than rods they are more suitable for fine grinding. Balls are also lighter so the kinetic energy of a single dropping ball is smaller than a rod.
The mills are Allis Chalmer type steel heads and usually supplied with white metal bearings however roller bearings are available on request. Larger mills can be supplied with gear boxes or direct synchronous motor drive and variable speed can be an option. Ball Mill or Rod Mill Spares
