· Fill up the two tanks of the cementing unit with water. With one pump start pumping at the maximum flowrate possible taking water from each of the cementing unit tanks alternatively and refilling the empty tank with the rig centrifugal pumps. Repeat the same operation with the other pump of the cement unit.
The Cement Manufacturing Process
· 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. The result is called ...

Cement and Lime | Tunstead
The Tunstead site is home to one of the largest limestone quarries in Europe, producing over six million tonnes of stone a year. The process is highly efficient as the extraction of limestone, production of lime and cement are all intrinsically linked and over 99% of quarried material is converted into saleable products and the remainder is used on site for restoration purposes.
