The cement manufacturing process starts with the mining of limestone that is excavated from open cast mines. Then this limestone is crushed to -80 mm size and is loaded in longitudinal stockpiles. Limestone is taken out diagonally from these stockpiles for grinding in raw mill hoppers. As mentioned earlier coal is used as a fuel to heat the raw ...

Abstract:- Cement is the basic material used for construction activities. The Cement manufacturing process mainly can be divided in to ten stages. From limestone loading to dispatching of cement various hazards takes place which causes harm.

2.2 Cement making 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.

Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.

The major raw material for cement production is limestone. The limestone most suitable for cement production must have some ingredients in specified quantities i.e., calcium carbonates, silica, alumina, iron, etc. Typically, cement plant locations are based upon the availability of good quality limestone in the vicinity.

Alternately, the cement can be mixed with just sand and water to create mortar, which is used to join bricks together. Concrete and mortar made of limestone can react to the carbon dioxide in rainwater and wear away. The resulting damage takes the form of gaps between bricks and buildings, which must be repaired by filling in the gaps.

Fiber cement boards. Limestone serves as filler in fiber cement siding, cladding and backer boards. It adds stiffness and strength to the final formulation and is used by many high-end producers in place of more abrasive silica fillers. During fabrication and installation, limestone helps prevent the generation of nuisance silica dust.

3/4" Crushed Limestone. Used for construction purposes, mainly as aggregate with or without a binder. Road base or road surfacing material are the major uses without a binder.
