Grinding behaviour of coal in different size-reduction ...

1987-1-1  It was found that it is easer to grind some coals in ball-race mills and others in tube mills. In this paper, simple laboratory methods are presented for evaluation of the grinding behavior of five coals in two different size-reduction operations. The tests proved that certain coals are better ground by impact than attrition and vice versa.

Coal Grinding - Cement Plant Optimization

Coal Grinding. To achieve good combustion and satisfactory flame formation, coal needs to be dried and ground to a proper degree of dryness and fineness. Drying of moisture in coal is achieved normally by ducting part of the kiln exhaust gas through the mill with inlet temperatures of up to 300°C. Inert kiln exhaust gases with oxygen content ...
