environmental impact due to cement production process in Srilanka. A case study of Puttalam Cement Company Ltd, (the only cement production facility that encompasses the entire production process) revealed that the production adopted the dry process, which includes supply of raw materials, clinker burning and grinding process.
The clinker is combined with small quantity of gypsum and then it is finely ground in a separate mill to get the final product. The mill is a large revolving cylinder containing steel balls that is driven by a motor.
Grinding Process Grinding is a surface finishing operation where very thin layer of material is removed in the form of dust particles. Thickness of material removed is in range of 0.25 to 0.50 mm. Tool used is a abrasive wheel Grinding machine is a power operated machine tool where, the work piece is fed
Grinding of clinker is the last and most energy-consuming stage of the cement manufacturing process, drawing on average 40% of the total energy required to produce one ton of cement. During this stage, the clinker particles are substantially reduced in size to generate a certain level of fineness as it has a direct influence on such
The cement grinding process include the admixture crushing, cement batching station, pre-crushing, high and fine powder grinding, fine powder separation, dust treatment, automatic control and other technologies. The finished cement can meet the requirement for high yield, high quality and energy saving. cement grinding unit with ball mill system.
