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.
As for the vertical lime kiln, it consists all three stages all in one. Usually, the upper side of the vertical shaft lime kiln is the preheating chamber. The central part is calcination chamber and the lower part of the lime kiln is cooling chamber. In light of this design, feed limestone with required sizes will be fed into the lime kiln from ...
Shaft kiln, also called vertical shaft kiln or vertical kiln, is a kind of vertical set stationary cement kiln, usually applied in the cement production line, lime production line, etc. As one of the main cement equipment, it plays the same role as a cement rotary kiln for cement clinker manufacturing, also composed of preheating zone ...
