Rapid cooling of clinker can mitigate the expansion problems, however higher MgO causes ball formation in kiln, increases melt phase etc. and therefore, can disturb kiln operation. Alkalies A part of alkalies Na 2 O and K 2 O combines chemically with clinker minerals, while as the major part remains as water soluble and affects adversely cement strength (28 Day Strength).

Cement is typically made from limestone and clay or shale. These raw materials are extracted from the quarry crushed to a very fine powder and then blended in the correct proportions. This blended raw material is called the ''raw feed'' or ''kiln feed'' and is heated in a rotary kiln where it reaches a temperature of about 1400 C to 1500 C.

Drilling Speed and Feed Calculator Determine the spindle speed (RPM) and feed rate (IPM) for a drilling operation, as well as the cut time for a given cut length. Drilling operations are those in which a cutting tool with sharp teeth, such as a twist drill, rotates and feeds into the workpiece axially, forming a hole with a diameter equal to that of the tool.
