Dry Grinding Attritor are designed and manufactured in batch operating as well
as continuous operation. Compare to Ball Mill, they are compact so the required
less space and low in cost. Batch types Attritor are faster and more efficient in
comparison to Ball Mill. But it has limitation of feed material size with respect to
Ball Mill.
1) BATCH ATTRITOR
In Batch Attritor, the material is charged from top of the grinding chamber and to grounded for certain period to achieve desired fineness than it will be discharged from bottom discharge screen and suitable discharge valve. The grinding effect is created in Attritor in a stationary tank grinding chamber by random motion of grinding media achieved by agitator with vertical shaft having horizontal arms.
2) CONTINUOUS ATTRITOR
In continuous Attritor, the material is charged from top of the grinding chamber and passes through agitating grinding media, where it is grinded to the desired particle size than it is discharged through discharging screen from grinding chamber.
