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.
As we have known the varieties of ball mill lets come back to the point and talk about the ways to increase ball mill efficiency Generally speaking there are three simple and direct means to increase ball mill output The first one is to allocate an impact crusher before the grinding mill As a result the mineral stone will be first.
A big adjustable flycutter can cover the most territory in the fewest passes and will often leave the most pleasing finish However you can convert even a regular facemill into a flycutter simply by removing all but one insert The best efficiency occurs when 23s.
However when the calculated apparent cumulative grinding rates increase from the smallest to the largest particle sizes the potential for increasing efficiency with a media size change is greatest A suitably sized torquemetered test mill can be used to experiment with the currently used plant ball charge and alternative ball charges.
