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.

Due to limitation of the mill's rotational speed, the smallest ball size is usually restricted to about 15 mm. Cement grinding using stirred mills (Pilevneli and Azizli, 1999) indicates that using smaller media (5-8 mm range) improves grinding energy efficiency up to 50% using stirred mills.

After cooling, the clinker may be stored temporarily in a clinker store, or it may pass directly to the cement mill. The cement mill grinds the clinker to a fine powder. A small amount of gypsum - a form of calcium sulfate - is normally ground up with the clinker. The gypsum controls the setting properties of the cement when water is added.

Raw Materials of Cement. Most important raw materials (what is cement made of) required in the manufacture of Portland Cement are: Limestone, Clay, Gypsum, Fuel, and Water (in wet method). 1. Limestones: These are sedimentary, calcium carbonate rocks (CaC0 3 ). Most commonly they contain a small amount of magnesium carbonate also.

in Exapilot. No procedures are missed, operator workload is reduced, and mill start-up can be completed in 20% less time. This is especially advantageous because the plant is operated at night to take advantage of cheaper electricity rates and workers on the night shift often have to perform the start-up and shutdown procedures.

A junk sub placed in the string above the mill can aid in catching the larger cuttings. Whenever possible, a stabiliser should be run within 60 or 90ft (20-30m) above the mill to prevent it from moving eccentrically. The stabiliser OD should not exceed the dressed OD of the mill. Always start rotating, with low rpm about 3ft (1m) above the fish ...
