In this method for producing a Portland cement clinker, when a clinker is obtained by pulverizing a mixed starting material and by firing said pulverized starting material, the starting material is pulverized by using, for example, a ball mill until the sieve retention at 90 μm becomes 20 mass% or more and 26 mass% or less. When firing a Portland cement clinker, the heat consumption rate ...

Portland Pozzolana Cement is a type of cement, produced by mixing Portland cement clinkers with Pozzolana material like fly ash. After that, the clinkers and pozzolanic material are mixed and then ground together. As per the Indian Standard (IS-1489) Pozzolana material is usually mixed in the proportion of 15 to 35 % by mass of the cement.

Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color.
