Jan 11 2016 by Pharmapproach July 5 2020 in Particle Size Reduction Equipment 8. A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 of the mill volume and its size depends on the feed and mill
Generally filling the mill by balls must not exceed 30–35 of its volume. Productivity of ball mills depends on drum diameter and the relation of drum diameter and length. Optimum ratio between length L and diameter D L D is usually accepted in the range 1.56–1.64.
Nov 18 2008 Basic principle Ball mill is generally used to grind material 14 inch and finer down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills they must be operated in a closed system. There is a specific operating speed for most efficient grinding.
Ball mill; an example of grinder is an efficient tool for size reduction of solid through grinding for many applications e.g. in chemical industry.Grinding means sub dividing the solids to a finer product than crushing.
