This is fed to the cement kilns where the cement clinker is made at high The process where dry powder is used is called dry process. Wet Cement Mill Process are also popular. Here the slurry is made by crushing or grinding the lime stone, bauxite with water. This is then fed to the kiln through the kiln feed tank.
The slurry is introduced into a rotary kiln, a lengthy cylindrical boiler that rotates on its axis. The kiln consists of three zones: the upper zone, known as the preheating zone, where hot gases from the lower zone dry and heat the slurry; . the middle zone, known as the calcining zone, where a temperature of about 1500 °C is reached …

The power ingesting of a grinding process is 50-60% in the cement production power consumption. The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 30-40% associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large time
Keywords: Wet Process; Dry Process; Cement; Crushing; Milling; Nigeria 1.

A common misconception is that once cement looks dry, it's ready for use. However, as we've seen, surface dryness is just a small part of the overall concrete curing process. Even if the cement appears dry after a day or two, its internal hydration process might continue for weeks, allowing it to develop strength and durability. 7.
