Industrial experience with clinker grinding in the ...
Abstract: Comminution is an important element for cost evaluation in any cement plant, mainly in relation to the power consumed, which is about 80 to 90 kW for a cement plant. In the early 90s, grinding in cement plants was operated mainly by vertical mills for raw material with rather good results in the majority of cases, and by tube mills for cement, with some …
CLINKER FROM ROTARY OR VERTICAL SHAFT KILN - Page 1 of 1
Re: CLINKER FROM ROTARY OR VERTICAL SHAFT KILN. There are a number of reasons why the clinkers might differ, but buying clinker from a VSK would not be a completely wrong move. It would depend on the degree of combination of the clinker, the lime saturation and the silica modulus. There are at least 2 principle reasopns why the clinker from …
