The grinding if clinkers in modern plants is carried out in the cement mill which contains chromium steel balls of various sizes. These balls roll within the mill and grind the mixture which is collected in a hopper and taken in the bucket elevator for storage in silos. The cement from silos is fed to the packer machines.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.
