The Cement Manufacturing Process Advancing Mining

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 down and then they are recombined into new compounds.

Optimising Cementing

The Cementing Process The three principal objectives of the primary cementing process are: 1. To isolate formations restricting fluid movement and sealingoff lost circulation or thief zones; 2. To support and bond the casing to the formation; 3. To protect the casing from corrosion and reinforce it against the shock loads in drilling deeper.
