The preliminary grinding is achieved by using a gyratory type of crushers whereas for fine grinding use is made of tube mills. The tube-mill crushers are generally provided with air separators through which material of desired fineness can only pass. The coarser, portion of the cement is fed back into the mill for further grinding.
