Get A QuoteCement manufacturingis a complexprocessthat begins with mining and thengrinding raw materialsthat include limestone and clay, to a fine powder, calledraw meal, which is then heated to a sintering temperature as high as 1450 °C in acement kiln. In this process, the chemical bonds of theraw materialsare broken down and then they are recombined into new compounds.
