Aug 30, 2012· Cement Manufacturing Process Phase 1: Raw Material Extraction. Cement uses raw materials that cover calcium, silicon, iron and aluminum. Such raw materials are limestone, clay and sand. Limestone is for calcium. It is combined with much smaller proportions of sand and clay. Sand & clay fulfill the need of silicon, iron and aluminum.
Aug 20, 2015· 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 clinker, which are rounded nodules between 1mm and 25mm across. The clinker is ground to a fine powder in a cement mill and mixed with gypsum to create cement.
mills, roller mills, or roller presses are often applied to ground clinker with additives in cement mill. The finished cement is being transferred via bucket elevators and conveyors to silo for storage . Figure 2: Cement Manufacturing Process 3.

Figure 22.214.171.124-1. The cane is received at the mill and prepared for extraction of the juice. At the mill, the cane is mechanically unloaded, placed in a large pile, and, prior to milling, the cane is cleaned. The milling process occurs in two steps: breaking the hard structure of the cane and grinding the cane. Breaking the cane
Pre- homogenized raw coal is feed in to the coal mill hopper with the help of belt conveyer. 44. Coal Mill(Contd.) • The raw is then fed to the coal mill VRM via weigh feeder, drag chain and screw conveyer. • Coal Mill is an important integral part of cement plant. Here large size of approx size 600mm, is ground fine to the size of 90 micron.

Normally pugmill-type mixers are used. The mixed soil-cement is then hauled to the jobsite and spread on the prepared subgrade. Compaction and curing procedures are the same for central-plant and mixed-in-place procedures. There are four steps in mixed-in-place soil-cement construction; spreading cement, mixing, compaction, and curing.
