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 mill Wikipedia the free encyclopedia A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing Principleedit A ball mill works on the principle of impact and attrition size reduction is done by impact as the balls drop from near the top of the shell Read More
and with the decreased grain size the necessary ball size also decreases Olejnik 2010 2011 For each grain size there is an optimal ball size Trumic et al 2007 The bigger ball in relation to the optimal one will have an excess energy and consequently the smaller ball mill has less energy necessary for grinding In both
Calculate and Select Ball Mill Ball Size for Optimum Grinding Based on his work this formula can be derived for ball diameter sizing and selection Dm 6 log dk d05 where D m the diameter of the singlesized balls in mmd the diameter of the largest chunks of ore in the mill feed in mm
The volume of a mill varies as the square of the diameter while the horsepower necessary for the mill rotation varies as the 26 power of the diameter A mill 8 feet in diameter requires 40 to 80 times more horsepower than a mill 2 feet in diameter
Ball Mills Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800s The basic construction of a ball mill is a cylindrical container with journals at its axis The cylinder is filled with grinding media ceramic or metallic balls or rods
