Cement Production: Raw Meal Production in Steps

2. Raw meal production The crushed limestone is ground into raw meal. Additives such as clay, sand or iron ore result in the desired chemical composition. The MULTIDOS® H weighfeeders and MULTIDOS® VPD apron feeders feed the various materials into the raw mill accurately and reliably. The raw meal is then homogenised in the blending silos.

Process Fans Used in Cement Industry - Reitzindia

Raw Mill Exhaust Fans. Raw mill exhaust fans or stack fans are also called as de-dusting fans. In cement industry raw mill exhaust fans handle 2.2 ton of exhaust gases for the production of 1 ton of clinker. Raw mill exhaust fans are operated with very adverse situations because the fan handles mainly gases such as CO2, N2, NOx and Sox along

Characteristics of mercury cycling in the cement

The mercury mass flows in the raw mill system was the largest in both of the two plants, accounting for 73% and 57% of the total mercury mass flows in Plants 1 and 2, respectively. Therefore, it is obviously important to focus on the mercury cycling in the raw mill system for mercury emission control of cement plants.

Mercury Speciation and Mass Distribution of Cement

The total Hg mass output was calculated to be 61.374 and 204.596 mg-Hg per metric ton-clinker (mg ton–1) for cement Plants 1 and 2, respectively. The Hg emission factors for Plants 1 and 2 were thus 0.059 and 0.196 g-Hg per metric ton-cement (g ton–1), respectively.

Integrated Pollution Prevention and Control (IPPC) Reference

SO2 emissions from cement plants are primarily determined by the content of the volatile sulphur in the raw materials. Kilns that use raw materials with little or no volatile sulphur have SO2 emission levels well below this level without using abatement techniques. The current reported emission range is <10-3500 mg SO2/m 3.

Clinkerization - Cement Plant Optimization

Sulphur in raw meal increases SO x emission and causes build-up in preheater. Sulphates needs to balance alkalies in kiln system. Excess sulphates can be calculated as: Sulphate Excess= SO 3-0.85 x K 2 O-0.65 x Na 2 O (g/100kg clinker) Cl chlorides can come from raw materials and fuel. Chlorides form stable compounds with alkalies and are
