The ball mill is a tumbling mill that uses steel balls as the grinding media The length of the cylindrical shell is usually 1–15 times the shell diameter Figure 811The feed can be dry with less than 3 moisture to minimize ball coating or slurry containing 20–40 water by weight
Ball Mill SlideShare We discuss the types of ball mill the basic principles of the ball mill how it works the details of design including equations for optimum dimensions in all cases some manufacturers for the ball mill and estimation of the cost the ball mill
Basic Components Of A Paint Grinding Mill Ball mill operating principles components uses 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 axishe balls which could be of different diameter occupy 30 50 of the mill volume
Ball Mills In all ore dressing and milling Operations including flotation cyanidation gravity concentration and amalgamation the Working Principle is to crush and grind often with rob mill ball mills the ore in order to liberate the minerals
Nov 18 2008 · Equations of the design By knowing the capacity quotCquot ton of the feed we can get approximately the length quotLquot mm and diameter quotDquot mm of the batch ball mill form D 1242C 4857 L 8571C 1854 Volume of mill 2 The bulk volume of balls charge ratio to the volume of mill is known as Filling ratio and its range is 3045 2 Note There
The design of a ball mill can vary significantly depending on the size the equipment used to load the starting material feeders and the system for discharging the output product The size of a mill is usually characterized by the ratio “length to diameter” and this ratio most frequently varies from 05 to 35 The
