Get PriceThe disadvantages of ball mills include their considerable metal consumption and deterioration grinding media as well as a lot of noise Most of the energy useless lost during ball mill operation leading to low it efficiency But even a significant specific energy consumption for grinding material compensates beneficial effect by using mill
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
Ball Mills Metallurgist Mineral Processing Engineer Working Principle Operation The apparent difference in capacities between grinding mills listed as being the same size is due to the fact that there is no uniform method of designating the size of a mill for example a 5′ x 5′ Ball Mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all
Ball milling is one of the few unit operation that improves with increasing mill diameter If acceptable results can be obtained with a 12” jar mil then good result will certainly be obtained with a 72” diameter mill Of course there is the possibility of over milling obtaining a different particle size distribution or a need to change
