fineness control of cement by separator

Manufacturing Process White Cement jkcement

The classifier (high efficiency separator) controls the fineness of white cement. The finished product of desired chemical composition and physical properties is transported to Cement Silos for storage. White cement is drawn from cement silos, for packing in bags by electronic rotary packer and in small pouches by Fill, Form and Seal machines.
