Cement Clinker Quality ControlCoal fines Coal fines are usually prepared by air swept coal mill or vertical mill. In order to produce highquality clinker, the fineness of coal fines should be controlled at about 12%, and its moisture content should be controlled within %. The machines that are usually used to dry the coal fines are rotary dryers.
ClinkerizationThe amount of free lime in clinker indies incomplete burning and needs to be monitored. When coal is used as fuel, the ash content and its composition should be considered in raw mix design. LSF of clinker lies in the range of 9298. Higher LSF at controlled free lime content translates to better quality of clinker (high C3S), difficult clinkerization, high heat consumption.
