Portland cement dry process steps

Step 2 – Material Grinding: At least 3 tons of materials (including various raw materials, fuel, clinker, etc.) need to be ground to produce one ton of Portland cement. According to statistics, the grinding process in the dry process of cement production line consumes more than 60% of the power of the whole plant, of which raw material

    Portland cement (the only type of cement in common use today) is manufactured in a four step process. Step 1 - Quarrying Limestone and a 'cement rock' such as clay or shale are quarried and brought to the cement works. These rocks contain lime (CaCO3), silica (SiO2), alumina (Al2O3) and ferrous oxide (Fe2O3) - the raw materials of cement
