experimental study of charge motion in a tumbling ball mill

Discharge of pebbles, finer rock, ball scats and slurry from mills and its flow through trommels, and into other processing operations has strong impacts on overflow ball mill performance. In this paper, the milling parameters of high energy ball mill (Fritsch Pulverisette 7) like vial geometry, number and size of balls and speed of the mill were modelled and discussed. Simulations through discrete element method (DEM) provide correlation between the milling parameters. A mathematical model is used to improve and develop this process.

Jan 02, 2017 The motion of balls deep within the charge of a rotary grinding mill was analyzed. This was an extension of earlier work in which the influence of liner design on the motion of the outer grinding media was modelled. Novel investigative techniques were used to track the motion of the balls, including X-ray filming at 50 frames per second of both Mill Type Overview. Three types of mill design are common. The Overflow Discharge mill is best suited for fine grinding to 75 106 microns. The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 250 microns.
