The total feed to the ballmill was therefore T. per hr. or 179 per cent, of the original feed. It was evident that the ballmill was greatly underloaded in this test, but so much trouble developed in the classifier, due to the tendency of the sands to slip down the slopes, that a more rapid feed was not attempted at this time.

Ball mill. A typical type of fine grinder is the ball mill. A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.
Jul 20, 2019· 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.

Cylindrical Ball Mills. The only cylindrical ball mills in common use are those of the grate discharge type, the most important being the Marcy and the AllisChalmers mills. Fig. 10 illustrates the construction of the Marcy Ball Mill. The cylindrical shell and the feed and discharge heads are made of cast semisteel.
The theoretical critical speed of a ball mill is the speed at which the centrifugal force is sufficiently large to cause a small particle to adhere to the shell interior for a full revolution of the mill. The common range of mill speeds is 65% to 80% of critical, depending on mill type, size and the application.
