How cement is made. Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln. In this process, the chemical bonds of the raw materials are broken …

Clinker is the mainstay or spine of cement production. Essentially, it is a mix of limestone and minerals. These are heated together in a rotary kiln at high temperatures – the chemical transformation results in small nodular aggregates, which is the clinker. The components of the clinker decide the properties of cement.

The effect of severity of prevailing condition, inside the kiln, can be mitigated by the formation of a stable coating on the refractory surface. Three different conditions related to coating formation may arise, namely: 1. Stable coating formation of normal thickness, with minimum stress on the Refractory lining. 2.
