Ball
Mill
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 shell diameter
2700mm, the main bearing is completely closed self-aligning 120°bearing
with Babbitt alloy of high lead and low tin with low hardness, underneath
laid with 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 to the 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 the rotation 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 the mill.
