Product Details
Depending on the type of grinding required, two types of ball
movement are distinguished:
- Cataract movement (grinding because of impact and friction)
- Cascade movement (grinding because of friction)
At the cataract movement balls are lifted higher and more balls are
ejected from the surface at the top of the mill. These balls fall
freely. Grinding takes place mainly because of the impact forces.
Cataract movement is used for coarse grinding in the 1.
compartment. Lifting liners in this compartment assist the cataract
movement.
Cascade movement is used in the fine grinding compartment. The
balls are carried up by friction and roll down at the surface.
Grinding takes place mainly because of friction.
The movement of balls depends on:
- Mill speed
- Ball charge
- Liner shape
- Mill diameter
- Replace the lubricant within the specified period. The lubricating
oil at the main bearing of the newly installed mill shall be
completely renewed after the mill runs for 1 month.
- Regularly check the quality and quantity of lubricating oil, remove
impurities in the oil, and replenish in time.
- Pay attention to the temperature change of the main bearing and
hollow shaft at any time.
- Pay attention to whether there are abnormal vibration and noise in
the operation of the equipment.
- Check the wear of lining plates in different parts frequently and
replace them in time.
- Check the sealing condition of the machine and whether the bolt is
loose.
