IV BALL MILLS Ball mills are one of the more common mills and use a closed cylindrical container that is rotated horizontally on its axis so that the media cascades A typical ball mill has an LD ratio of 151 Ball mills are filled with spheres or other shapes made of steel or ceramics or with pebbles made of flint or of an ore being ground
Jan 11 2016 · 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 size
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 811 The feed can be dry with less than 3 moisture to minimize ball coating or slurry containing 20–40 water by weight
May 22 2019 · 22 May 2019 The ball mill consists of a metal cylinder and a ball The working principle is that when the cylinder is rotated the grinding body ball and the object to be polished material installed in the cylinder are rotated by the cylinder under the action of friction and centrifugal force At a certain height it will automatically fall and impact and grind the material in the cylinder to grind the
