Description:

Ball mill is widely used for milling various kinds of ores or rocks in metal and
non-metal mining and building material industry. The main bearing of the ball mill
with the shell diameter 900-2100mm is spherical liner bearing; for the shelldiameter 2700mm, the main bearing is completely closed self-aligning 120 bearing
with Babbitt alloy of high lead and low tin with low hardness, underneath laidwith cooling copper piping full of water The bearing is of static pressure structure
with high and low pressure united oil lubricating system.Ball mill components: A ball mill operates by rotating a cylinder with steel grinding
balls, for the ball to fall back into the cylinder and onto the material tothe ground. The rotation is usually between 4 to 20 revolutions per minute, depending
upon the diameter of the mill. The larger the diameter is, the slower therotation will be. If the peripheral of the mill is too great, it begins to act like
a centrifuge and the balls do not fall back, but stay on the perimeter of themill. Illustration of how ball mill works:Ball mils are generally used to grind material 1/4 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 continuously beingrecalculated back to the mill to be reduced
