aracting in the ball mill

For ball milling you can assume a porosity of about 035 to 040 the volume of space between the balls and you can normally assume the pulp surface level is equal to the ball charge surface level So do a crashstop and measure the volumetric filling of the charge then multiply that volume by

gravity due to its weight along G The resultant force along P The centripetal force is C The force of gravity is P To maintain the position of the ball in the mill the condition C P should be satisfied if the angle becomes 90 o where D is in meters Generally the mill speed is maintained at 70 to 75 of the critical speedApr 03 2013 Planetary Ball Mills Planetary ball mills are the most

Answers Aug 18 2012Ball Mills are generally used to grind material 14 inch and finer down to the particle size of 20 to 75 microns To achieve a reasonable efficiency with ball mills they must be operated in a closed system with oversize material continuously being recirculated back into the mill to be reducedThe drive of the ball mill consists of an induction electric motor twostage gearbox and the pinion gear This pinion gear is mated with the girth gear mounted on circumference of the ball mill shell and in that way it transfers the motion from the drive to the shell see Figure 1 taken from 1 Figure 1 Mechanical system of a ball millBallRod Mills based on 4 liners and capacity varying as 26 power of mill diameter on the 5 size give 20 per cent increased capacity on the 4 size 25 per
