The liquid percentage at 1450 0 C can be estimated using the formula. % Liquid content (1450 0C) = 3.0 x A+2.25 x F+S. Where A=Al 2 O, F=Fe 2 O 3, S= MgO+K 2 O+Na 2 O+SO 3 In Clinker. The normal range of liquid phase is 22-27%. Burnability is a reference value for raw meal indicating how difficult it is to burn.

A cement mill is a grinding machine that used to grind hard, nodular clinker from cement kiln into fine powder that is cement. At present, most cement is ground in ball mills. As the rapid development of construction, more and more cement are required. Grinding systems are either 'open circuit' or 'closed circuit.'.
