Ball Mill Working Principle And Main Parts

Ball mill working principle to be chosen according to the grinding material material is composed of a ball mill feed end of the hollow shaft is arranged in the tube body when the ball mill cylinder rotation time grinding body due to inertia and centrifugal force the effects of friction making it attached to the cylinder liner on the cylinder body away when taken to the height of a

Construction Of Ball Mill Ball Mill Structure Henan

Jan 14 2019 the diameter of the mill determines the pressure that can be exerted by the medium on the ore particles and in general the larger the feed size the larger needs to be the mill diameter the length of the mill in conjunction with the diameter determines the volume and hence the capacity of the mill figure 1 ball mill
