Ball Mill Vs Rod Mill How To Choose Ball Mill Or Rod
the overall design of ball mills and rod mills are compact, with simple operation and easy maintenance. but the both are different in performance and applications. In this article, the similarities and differences between ball mills and rod mills are analyzed from aspects, and suggest how to choose ball mill or rod millplanetary ball mills have been proven their applicability as reactors for organic syntheses from different points of view. performance of chemical reactions in the solid state without a solvent takes advantage of the high mixing efficiency of ball mills and the continuous particle refinement resulting in sep 01, 1991 scanmec designs traditional mills of all sizes from 100 to 4,000 kw, but for large mills it prefers the shell-supported design, with or without a wrap-around motor. the first installation of this type, built in conjunction with aker trondelag as, was the sydvarager ball mill, diameter by long, powered by an 8.1 MW siemens wrap grinding media in coarse-grinding chambers, i.e. balls of up to 100 mm in cement mills and balls of up to 100 mm in dry-process raw mills. the ducrostep shell lining is a fully bolted on lining except for
