Limestone mill grinds limestone into powder, limestone powder has different specifications it can be used to produce anhydrous calcium chloride which is the main auxiliary raw material of sodium dichromate production. it is the main raw material.
Manufacturing of cement involves various raw materials and processes. each process is explained chemical reactions for manufacture of portland cement. cement is a greenish grey colored powder, made of calcined mixtures of clay and limestone..
The raw meal is then heated and burned in a pre-heater and kiln and then cooled in an air cooling system to form a semi-finished product, known as a clinker. clinker 95 is cooled by air and subsequently ground with gypsum 5 to form ordinary portland.
A kiln bypass system can also be used in a dry system, in which case the initial raw meal will not be fed in slurry form and the raw meal crushing means will be a raw mill instead of a drier crusher, cement raw meal in the form of slurry is fed.

By replacing potassium feldspar with white cement, anorthite was appearance in fired body at 1250 c. this replacing decreases bulk density, linear shrinkage and modulus of rapture. although, water adsorption and consequently firing temperature increase.
At that temperature, a chemical change takes place and the raw materials turn into a hard, nodular solid known as clinker. after cooling, the clinker is ground in a ball or roller mill to produce cement powder. approximately five . mpa cement.
