13 factors affecting location of industries. 1. availability of rawmaterials or nearness to rawmaterials: availability of raw materials or nearness to raw materials is a primary factor which governs location of industries. an industry is located in that place where raw materials are available in abundance and at cheaper rates.
The degree of homogenization of raw materials and raw materials in cement plants is an important factor in determining the quality of the final product. in order to make full use of lowgrade limestone, expand the raw material resources and improve the quality of clinker, modern cement factories attach great importance to the prehomogenization of raw materials.
Lime component limestone: common forms of calcium carbonate used as raw material for cement manufacturing are limestone and is of predominantly fine grained crystalline structure, its hardness is between 1.8 to 3.0 of the mohs scale of hardness and specific gravity 2. to 2.8. limestone usually contains admixtures of clay substance or iron compounds,.
Limestone comprises 95 of core raw material for cement production. no wonder then that the cement sector governs demand, supply and pricing of limestone (as well as coal) to some extent. according to some estimates, around 180250 kg of coal and about 1.5 tonne of limestone is required to produce a tonne of cement.

Stage of cement manufacture. there are six main stages of cement manufacturing process. stage 1 raw material extractionquarry. the raw cement ingredients needed for cement production are limestone (calcium), sand and clay (silicon, aluminum, iron), shale, fly ash, mill scale and bauxite. the ore rocks are quarried and crushed to smaller pieces of about 6 inches.
Technically, a cement producer can have almost complete control over clinker composition by blending raw materials of different compositions to produce the desired result. in practice, however, clinker composition is largely determined by the compositions of the locallyavailable raw materials which make up the bulk of the raw meal.

The preheated raw materials roll down the kiln and get heated to such an extent that the carbon dioxide is driven off with combustion gases. the material is then heated to temperature of nearly 1400 c to 1500 c when it gets fused together. the fused product is.
The raw materials which supply cement works, and which may be required in quantities of over 4,000 tonnes per day, must be thoroughly proven if the plant is to run successfully. consistent quality feed is required and an extraction plan must be made to ensure that a uniform flow of raw material will always be available to the kilns.
The whole process of cement manufacturing in messebo cement plant which consists of two separate cement production lines can be summarized into the following processes ;as can be seen in the process and quality flow diagram below; 1. quarrying and crushing 2. raw material storage and transportation 3. proportioning 4.
This is a fluxing agent which reduces the melting temperature of the raw materials in the kiln (from 3,000 o f to 2,600 o f). it hydrates rapidly, but does not contribute much to strength of the cement paste. by mixing these compounds appropriately, manufacturers can produce different types of cement to suit several construction environments.
