The rod mill is driven by the motor through the reducer and the
peripheral big gear reduction drive or by the low speed synchronous
motor directly through the peripheral big gear reduction drive, the
drive drum rotation. The barrel body is equipped with appropriate
grinding media - steel bars. Under the action of centrifugal force
and frictional force, the grinding media is lifted to a certain
height, and the grinding medium falls off and falls off. By
grinding material from the feed port continuous into the cylinder
and the movement of the grinding medium crushing, and through the
overflow and continuous feeding power products will be discharged
out of the machine, for the next period of process operation. The rod mill grinding medium for grinding rod, generally
grinding rod length should not be more than 7 meters long, because
the rod mill is very easy to cause the winding, therefore, the
length of rod mill, not too long, grinding rod diameter of 75~150
mm. The grinding rod should have sufficient rigidity and hardness in
the process of using straight without bending, should not be very
brittle, so as not to wear small enough in diameter and broken into
pieces, but enough hours in wear, should be broken into small
pieces, in order to discharge from the rod mill. If the rod mill is
too soft, easy in the cylinder to rotate when bending, bending
caused by grinding and premature failure of winding, winding rod
grinding mill caused by difficult cleaning, waste of time. |
