The material flow route for a cement plant was obtained. Three mass balances for three cement production stages were established. Each ton of products requires 2.48, 4.69, and 3.41 t of materials in three stages. Waste gas recycling rate in clinker production is higher than in other stages. Recycling waste gas discharged from raw and cement ...

The process of manufacture of cement can be divided into three basic steps, preparation of raw materials, pyroprocessing to produce clinker, and grinding and blending clinker with other prod- ucts to make cement. The raw materials obtained from the quarry are crushed, ground and mixed as a slurry in the wet process and a powder in the dry process.

the quantity of mercury emitted by different cement plants can vary significantly. Specific emissions are dependent on the amount of mercury in the raw materials and fuels, as well as the manufacturing process (Schorcht et al. 2013). The range of mercury emissions from the European cement industry is reported to vary between levels that

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. m R = m P + m W + m S (where (sigma) denotes the sum of all terms). m R = m R1 + m R2 + m R3 = Total Raw Materials. m P = m P1 + m P2 + m P3

4 Due to the interaction of raw materials and kiln gases, rotary kiln systems have inherent SO2 removal efficiencies ranging between 40-99% of the sulfur input to the system. The literature suggests that 50-70% of the remaining SO2 will be removed from exhaust gases when passed through an in-line raw mill system.

Mercury enters in the cement manufacturing process as a trace element with the raw materials and the fuels. The mercury content of natural raw materials varies between individual raw material deposits and even within the same deposit. In fuels, the amount of mercury can vary in a similar way, depending on the fuel type and the fuel source.
