Explain dry and wet process of cement manufacturing

13/12/2018  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 multi-chamber tube mil of a fairly large diameter. The drying unit consists of a grade firing with an induced draught fan. The grinding and drying operations are carried out simultaneously. This dry

CEMENT RAW MATERIALS

The process of cement making is, however, remarkably flexible in terms of the raw materials that can be used to achieve required chemical compositions. Many limestone deposits, provided they are low in MgO, easily meet the requirements and a number of other CaO-containing raw materials are known to be used. Alternative materials include marble, chalk, marl, shell deposits, blastfurnace slag ...

1.Dry cement process (1). Crushing and Pre-homogenizing. Most of the raw materials, like limestone, clay, iron ores, and coal, should be crushed before their pre-homogenization. Limestone is the primary material in this line, and due to its large particle size and high hardness, it’s good crushing plays an important role in the whole line. Special stacking and reclaiming technology has been used in the pre-homogenizing process

The cement kiln - Understanding Cement

The basic dry process system consists of the kiln and a suspension preheater. The raw materials, limestone and shale for example, are ground finely and blended to produce the raw meal. The raw meal is fed in at the top of the preheater tower and passes through the series of cyclones in the tower. Hot gas from the kiln and, often, hot air from the clinker cooler are blown through the cyclones. Heat is

CEMENT RAW MATERIALS

Cement clinker is manufactured by heating the blended and ground raw material (typically limestone and clay or shale and other materials) to partial fusion. The clinker burning takes place at a temperature of 1450°C in kilns, which are normally inclined rotating cylinders lined with heat-resistant bricks. Clinker emerges from the kiln after several hours as

What is the manufacturing process of Portland Cement ...

DRY PROCESS. In the dry and semi-dry process the raw materials are crushed in a dry state. Then, they are processed in grinding mill, dried and reduced to very fine powder-like. That dry power is further blended, corrected for the right composition and mixed with the flow of compressed air. Nearly about one hour of aeration, a uniform mixture is obtained, that aerated power tends to behave like a liquid.
