At startup of a mill the grinding material rotated by a certain angle and grinding balls start to move by closed path the curved surface of natural slope is close to the plane inclined at some angle to the horizontal this angle is equal to a limit angle of rotation
Get DetailsMill breakage mechanism according to morrell 1996 the breakage mechanism is association with media characteristics impact breakage mb3 m b ball mass attrition breakage sb3 s b ball surface area the energy of impact will depend on height and the angle of impact the size reduction will depend on
Get DetailsAngle of breakage calculation in ball mill the specific rate of breakage due to self breakage mechanism for particles smaller than 12 5 mm is significantly low and can be ignored confidently the dominant breakage mechanism in this particle size range is impact breakage a standard laboratory ball mill was used to determine breakage get price
Get DetailsMay 24 2018 im surfacing a tungsten angle plate with a ball mill we used a 4 flute 2 mm ball mill to surface prior but due to the code being to long to run as a subprogram on the okuma we switched to a 6mm 6 flute ball mill i have a rougher and semi finisher i run prior both are 8mm

Get DetailsSep 01 2016 since breakage rate is defined as the number of breakage events per unit of time napiermunn et al 1996 one can reasonably expect that at the same mill rotational speed the large ball mill will provide more frequent breakage events per unit of time and with the greater kinetic impact energy level as a consequence particles in a large
Get DetailsBall mills tumble iron or steel balls with the ore the balls are initially 510 cm diameter but gradually wear away as grinding of the ore proceeds the feed to ball mills dry basis is typically 75 vol ore and 25 steel the ball mill is operated in closed circuit with a particlesize measurement device and sizecontrol cyclones
