20/06/2015 · 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. 4.
Wet process kilns. The original rotary cement kilns were called 'wet process' kilns. In their basic form they were relatively simple compared with modern developments. The raw meal was supplied at ambient temperature in the form of a slurry. A wet process kiln may be up to 200m long and 6m in diameter.
Due to ever increasing fuel costs the target was to change the plants operation from import coal with 25 % volatiles to local lignite coal with up to 40 % volatile matters and a moisture content of up to 20 %. For this reason the coal mill had to be modified form cooler middle air to preheater exhaust gas operation.
Cement grinding. The clinker from the pyroprocessing area is ground in ball mills or roll press + Ball mill combination or vertical roller mills to form cement. Commonly used separators are in closed circuit grinding are: O –sepa, Sepol and Sepax separators to achieve a finish cement fineness of 3000 – 4000 Blaine surface (cm2/gm).
Pulverized coal producing processes are widely used in thermal power stations, cement and ironsmelting industry. Many accidents and protection techniques have been reported by former investigations . Normally, the traditional coal process systems use ball mills to pulverize coal. Flue gases are used as drying and
