Sulphates may be present in clinker up to about 3% Sulphur in raw materials increases SOx emission and cause build-up in preheater Sulphate can form a stable compound with Potassium (K2SO4) and to lesser extent Sodium (Na2SO4) The sulphates in the clinker comes from raw materials and fuel
The choice of composition of materials mixture with useful components generally is determined by plant’s geographical location and delivery of raw materials The only common feature in all cement production plants is the difficulty of grinding the source material as the material is hard enough and has high abrasiveness
Cement is then pumped to silos for storage and dispatch Mineral additions and SCMs are added to reduce the amount of clinker in cement This in turn reduces the fuel, power, process emissions and raw materials associated with cement production At the same time it creates a use for material considered to be a waste product of other industri
116 Portland Cement Manufacturing 1161 Process Description1-7 Portland cement is a fine powder, gray or white in color, that consists of a mixture of hydraulic cement materials comprising primarily calcium silicates, aluminates and aluminoferrit More than 30 raw materials are known to be used in the manufacture of portland cement, and these
Raw materials for cement manufacture Materials used in the Cement Industry in Britain and Ireland Almost any mineral can be used in a cement rawmix, provided that the bulk composition of the mixture will produce the desired calcium silicates and fluxes (see clinker), and provided that certain deleterious components are minimizedBroadly speaking, minerals containing high levels of calcium .
Cement Clinker Production - an overview | ScienceDirect Topics
The material has been used effectively as raw feed for Portland cement clinker production and as cement, filler and fine aggregate components, though it is interesting to note that Avedoere Wastewater Services (2008) favoured its use as a filler over a cementitious component, because of the low degree of pozzolanic activity measured in this case
