Limestone Grinding. The job of grinding is done by the Vertical Roller Mill, which works like a cyclone to create a fine dust of evenly sized particles. As the feed is ground on the horizontal grinding table, hot air is pushed upwards from underneath forcing the smallest particles to rise. ... In the final manufacturing stage, gypsum is ...
Limestone provides calcium oxide and some of the other oxides, while shale and the other materials (silica sand, iron ore) provide most of the silicon, aluminum and iron oxides required for the manufacturing of Portland cement. Gypsum and Pozzolana are going to be used for final cement grinding together with clinker produced from kiln.
Algeria produces limestone-composite cement by inter- and separate-grinding of limestone and CEM I. The limestone is pre-ground in the raw material mill MVR 6000 R-6. Feed material to the MVR 6700 C-6 is clinker and gypsum. The pre-ground limestone is injected into the classifier outlet and is homogenised with the
