About this site

A Ball mill is a horizontal cylinder partly filled with steel balls (or occasionally other shapes) that rotates on its axis, imparting a tumbling and cascading action to the balls. Material fed through the mill is crushed by impact and ground by attrition between the balls. The grinding media are usually made of high-chromium steel. The smaller grades are occasionally cylindrical ("pebs") rather than spherical. There exists a speed of rotation (the "critical speed") at which the contents of the mill would simply ride over the roof of the m

Better and cheaper cement: Optimising raw material properties

Jun 24, 2021  Cement performance is intially set by targeting a clinker lime saturation factor (LSF). This gives the required product strength but also provides good clinker burnability and reasonable economy of operation. The LSF level is often around 95 or 96, although the optimum LSF will vary depending on the raw material properties and other factors.

From Waste to Value - Alternative Fuel in Cement Production

From there, the clinker is subjected to a grinding process where it is mixed again with other minerals and the resulting product is cement. Producing one ton of cement represents approximately 0.5 ton of CO2 and 100 kg of fossil fuel pet coke. The solid waste is used as an alternative fuel for kilns in the cement production plants.
