· The dry process for the manufacture of cement is preferred only in places where hard crystalline limestone and shales are available. The only advantage of this process is that the fuel consumption is low. The raw materials are first crushed together in the dry state in a multichamber tube mil of a fairly large diameter. The drying unit consists of a grade firing with an induced draught fan ...

The cement manufacturing process involves four distinct stages, and these are outlined below. Step 1 Quarrying The raw material for cement manufacture is a rock mixture which is about 80% limestone (which is rich in CaCO3) and 20% clay or shale (a source of silica, alumina and Fe2O3). These are quarried and stored separately. The lime and silica provide the main strength of the cement, while ...
