Closed-circuit Clinker Grinding Mill,Closed-circuit

In a closed circuit mill, the total throughput is higher and hence the size of material from the mill exit is coarser. Unlike the open circuit mill, material coming from the mill goes to an air separator where the finer materials are produced and the rejects are returned to the mill for regrinding.
