raw materials process manufacturing cement

Thecement manufacturing Processcan be broadly classified into following activities. Step No:Processdescription: 1:Raw MaterialAcquisition (Quarrying) 2:Raw materialpreparation: 3: Pyro-processing: 4: Fuel preparation - Coal grinding: 5: Finish grinding: 6:Cementstorage, packing and transport:

Thecement manufacturing processstarts from the mining ofraw materialsthat are used incement manufacturing, mainly limestone and clays. A limestone quarry is inside the plant area and a clays quarry is as far from the plant area as 25 km.

An ideal product, Tata Nirman is a substitute of sand, lime and cement - raw materials for manufacturing Fly Ash Bricks. It is also used as a partial replacement of limestone in clinker, a basic raw material for cement making. Tata Nirman assures of better strength, better quality.

For its raw materials, cement manufacturing uses minerals containing the four essential elements for its creation:calcium,silicon,aluminum, andiron. Most plants rely on a nearby quarry forlimestone. The most common combination of ingredients islimestonecoupled with much smaller quantities ofclay…

Burning : In this operation, the slurry is directly fed into a long inclined steel cylinder called Rotary kiln.Inthis kiln there are 3 different zones shown in fig. below.Cement Manufacturing ProcessFlow Chart (i) Drying Zones : In the wetprocess, the drying zone is comparatively larger than dryprocess. In is because theraw materialin slurry form is directly fed into the kiln which has ...

The most common raw rock types used in cement production are:Limestone(supplies the bulk of the lime)Clay,marlorshale(supplies the bulk of thesilica,aluminaandferric oxide) Other supplementary materials such assand,fly ash/pulverised fuel ash(PFA), orironstone…

The choice of composition ofmaterialsmixture with useful components generally is determined by plant’s geographical location and delivery ofraw materials. The only common feature in allcementproduction plants is the difficulty of grinding the sourcematerialas thematerialis hard enough and has high abrasiveness.
