A Review On Environmental and Health Impacts Of Cement ...

In a dry cement manufacturing process, dry raw mix contains less than 20% moisture by mass. However, in a wet process water is added to the raw mix to form slurry and then is transported to the kiln [11]. Raw meal or blended raw materials are fed into the upper end of the pre-heater tower and then passed through the end of the rotary Kiln.

4. MATERIALAND ENERGY BALANCE

The law of conservation of mass leads to what is called a mass or a material balance. Mass In = Mass Out + Mass Stored Raw Materials = Products + Wastes + Stored Materials. Σm R = Σm P + Σm W + Σm S (where Σ (sigma) denotes the sum of all terms). Σm R = Σm R1 + Σm R2 + Σm R3 = Total Raw Materials Σm P = Σm p1 + Σm P2 + Σm P3 ...
