Wet process and dry process of cement manufacturin
In nigeria, approximately 40 to 50 per cent of cement manufacturing cost is energy related; each tonne of ce- ment requires 60 - 130 kg of fuel oil or its equivalent and about 105 kwh of electricity, depending on the cement variety and process type employed . cement produc- tion spreads across five geo-political zones due to the.Wet process; dry process; wet process- the wet process was popular for the manufacturing of cement because of the possibility of more accurate control in mixing of the raw materials. in the wet process, the slurry contains 35 to 50 water. that is why, to dry the slurry more fuel is required.The mixing procedure of the manufacture of cement is done in 2 methods, dry process; wet process; a dry process the both calcareous and argillaceous raw materials are firstly crushed in the gyratory crushers to get 2-5cm size pieces separately.The wet process for the manufacturing of portland cement. in the wet process, limestone is first crushed to smaller fragments. then, it takes to ball or tube mill where it mixes with clay and finely ground. then, water adds to it to make a slurry. it pumps to slurry tanks, where it keep in an agitated condition by means of rotating arm or by rotary kiln.
The process of cement manufacturing consists in: the incorporation of raw materials to form a homogeneous mixture the burning of the mix in the kiln to form clinker the grinding of the cooled clinker, with the addition of a small proportion of gypsum, to a fine powder.Jul 09, 2020 the wet process of cement manufacturing is divided into a number of stages. a raw material extraction. b grinding. c proportioning and mixing and preparing composition based on the raw material purity. e preheating the composition. f burning the composition in a kiln to form clinkers.
Methods of manufacturing process of cement. at present portland cement is manufactured by two processes, dry process, and wet process. the main difference between these two methods of manufacturing of cement is that in the dry process, calcareous and argillaceous raw materials are fed into the burning kilns in a perfectly dry state.Oct 29, 2019 wet process. the wet process method is manufacturing raw materials slurry with 32-40 water content. wet process method’s advantage is that its good fluidity of raw materials slurry makes more even mixed materials and produces high-quality clinker. but it requires more heat consumption, so it is environment-friendly. flow-of-cement rotary kiln.
