Raw Mill / Ball Mill Grinder Widely Used In Powder-Making
Production Line
Raw Mill Introduction:
Raw mill is mainly used for grinding raw materials in cement plant
and is also suitable for grinding mineral ore and other materials
in metallurgy, chemical, power plant. It can work in open circuit
or closed circuit with separator. Raw mill has features of various
materials application, continuous running, big grinding rate, easy
control of product fineness.
The ball mill is composed of a horizontal cylinder, a hollow shaft
for feeding and discharging materials, and a grinding head. The
cylinder is a long cylinder with a grinding body inside the
cylinder. The cylinder is made of steel plate, and the steel liner
is fixed to the cylinder. Generally, it is a steel ball, which is
packed into the cylinder according to different diameters and a
certain proportion. The grinding body can also be made of steel.
Choose according to the particle size of the grinding material. The
material is loaded into the cylinder by the hollow shaft at the
feed end of the ball mill. When the cylinder of the ball mill
rotates, the grinding body is attached to the cylinder liner due to
inertia, centrifugal force and friction. Carried away by the
cylinder, when brought to a certain height, it will be thrown down
due to its own gravity. The falling grinding body will crush the
material in the cylinder like a projectile.
As an important choice of ore grinding equipment, the ultra-fine
grinder often produces a large number of dust in the operation,
which will not only damage the ecological environment, but also
seriously harm the health of workers. Therefore, how to effectively
solve the problem of ultra-fine grinder dust is an urgent problem
for the current ultra-fine grinder users.
In order to effectively solve the dust problem of the ultra-fine
grinder, we should have a detailed understanding of the causes of
the dust. Let's take a specific look at the causes of the dust in
the ultra-fine grinder.
