AIR SEPARATORS. Introduction. Separators are utilized in a closed circuit grinding system for the purpose of separating (classifying) the fine and coarse particles of the feed. The fine particles are passed through the separator to become finished product while the coarse particles are returned to the mill as rejects for further grinding.

So seperator is an important part of cement grinding system. The operating parameters of the seperator are related to the production of entire unit. If sorting efficiency of the seperator is higher, so is output of the cement mill. In the closed loop system, the focus of cement grinding is mainly on the role of relatively coarse grade particles.

This mill type has prevailed because of its reliability and the favorable properties of the cement ground with ball mills. Primary ball mills were operated as opencircuit mills, later, separators were added to produce improved cement qualities in a closedcircuit. The fundamental disadvantage of the ball mill is the relatively high specific ...

By centrifugal action, the separator sends the finer material out as product, and the coarser material back to be mixed with the clinker feed to the ball mill. The cement mill is illustrated in Figure 1. The clinker feed rate can be controlled. The separator may be subjected to a wide manual adjustment.
