in bags to the market. Cement clinker and finished cement are traded internationally. Cement manufacture is a very energy intensive process and results in the production of large amounts of carbon dioxide (CO 2). The carbon dioxide is chiefly produced when the calcareous raw material is calcined to produce calcium oxide. Generally around 0.5 tonnes

The commnation method belongs to the most efficient grinding processes applied in the cement manufacturing. Separation: the ground and dried material is lifted up with the drying gases. In the separator, the too coarse particles (tailings) are rejected to the grinding table. The fines leave the mill and are conveyed to dust collector.

The cement manufacturing process starts from the mining of raw materials that are used in cement 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. The limestone is excavated from open cast mines after drilling and blasting and loaded onto dumpers ...
