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.
Effect of grinding methods on characteristic and burnability of raw meal The effect of three grinding methods by ball mill, roller press, and vertical roller mill on performance and properties of silicate-sulphoaluminate composite cement gradation particle was studied.

2010-8-11Re MATERIAL RETENTION TIME IN A BALL MILL VRM. You could do that by measuring the material flowrate Qtonsh through the mill as well as the quantity Mtons of material that accumulates within the mill. The retention time, also called residence time, is the ratio MQ h .
2015-4-16Optimization of mill performance by using online ball and pulp measurements In the platinum industry, by increasing the solid content in the slurry, the product becomes finer. At a higher percentage solid than 73 to 74, the product becomes coarser again. At this level, a drop in grinding efficiency occurs. Figure 7.
The High Energy Ball Mill E max and MM 500 were developed for grinding with the highest energy input. The innovative design of both, the mills and the grinding jars, allows for continuous grinding down to the nano range in the shortest amount of time - with only minor warming effects. These ball mills are also suitable for mechano chemistry.
The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls.
