wet process manufacturing portland cement

Cement manufacturing process Full description cement manufacturing process requires patience and a lot of time and for this reason we confine ourselves only to name them Portland cement raw materials Portland cement raw material mainly consists of limestone and clay May 22 2013There are 2 chief aspects of the manufacturing process First To produce a finely divided mixture of raw materials – chalk / limestone and clay / shale Second To heat this mixture to produce chemical composition There 2 main process that can be used in manufacturing of Portland Cement that is i) wet process ii) dry process

Cement kiln

Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates Over a billion tonnes of cement are made per year and cement kilns are the heart of this production process their capacity usually defines the capacity of the cement plant

Wet Process (The rotary kiln is an essential and important component of a cement manufacturing factory It is made of a thick steel cylinder of diameter anything from 3 meters to 8 meters lined with refractory materials mounted on roller bearings and capable of rotating about its axis at

Raw material for manufacturing of Portland Cement Raw material for manufacturing of Portland Cement Calcareous material (Limestone [CaO] Chalk powder Alkali wastes ) Argillaceous material (Alumina [Al 2 O 3 ] Silica [SiO 2 ] iron Oxide [Fe 2 O 3 ] Clay) Pulverised Coal or Fuel oil Gypsum ( CaSO 4 2H 2 O)

In the manufacturing process major raw materials are blended with minor ingredients as required and processed at high temperatures in a cement kiln to form an intermediate material known as clinker Gypsum is interground with clinker to form portland cement Gypsum content is assumed to be added at 3 0% (by mass fraction) of portland cement

How is portland cement made? Cement manufacturers mine materials such as limestone shale iron ore and clay crushed and screened the rock and place it in a cement kiln After being heated to extremely high temperatures these materials form a small ball called "clinker" that is very finely grounded to produce portland cement

In the wet process the feedstock is ground and blended in the form of slurry Removal of this excess water necessitates the use of a longer kiln for the wet process The total power consumption in this process is also higher and the output lower than in the dry process However blending is much easier in a wet

Portland cement manufacturing is an energy intensive process in which cement is made by grinding and heating a mixture of raw materials such as limestone clay sand and iron ore in a rotary kiln The kiln is a large furnace that is fueled by coal oil gas coke and/or various waste materials

The kiln has to operate continuously in order to ensure a steady regime and therefore uniformity of clinker The larger existing kiln in a wet process plant produces 3600 tonnes of clinker per day The manufacture of cement by wet process is energy intensive and thus uneconomical as compared to dry process and semi dry process

Dec 24 2016The entire manufacturing process in a modern plant is now controlled through a microprocessor based programmable logic control system to maintain uniform quality of cement and a high rate of production The entire operation of the plant is controlled centrally in a single control room and the plant employs minimum of manpower The modern
