The larger existing kiln in awet processplant produces 3600 tonnes of clinker per day. The manufacture ofcementbywet processis energy intensive and thus uneconomical as compared to dryprocessand semidry process.
In addition, the raw material slurry can also be dehydrated into raw material blocks and put into the kiln to calcine clinker. This method is called thesemi-wet process, which still belongs to thecement wet processproduction. Advantages: thewet processofcementproduction has the characteristics of simple operation, low dust and easy conveying. Because the slurry has fluidity so that its homogeneity is good …
CEMENT MANUFACTURING– AWET PROCESSWITH THE FLOW DIAGRAM. Advantages: Raw material can be mixed easily, so a better homogeneous material can be obtained. Capital cost (Cost of establishment) is comparatively less. Disadvantages: Mixing of Raw materials in …
Dry process:Wet process: 1. Mixing of raw material in a dry state in blenders. 1. Mixing of Raw materials in wash mill with 35 to 50%water. 2. The dry materials exiting the mill are called “kiln feed”. 2. Materials exiting the mill are called “slurry” and have flowability characteristics. 3.
Explanation: Grinding and mixing of the raw materials in theirwetstate is calledwet processand grinding and mixing of the raw materials in their dry state is calleddry process.
Most newcement plantis of this type. The principle is similar to that of thedry process preheatersystem but with the major addition of another burner, or precalciner. With the additional heat, about 85%-95% of the meal is decarbonated before it enters the kiln. Basic principle of a precalcinercement kiln.

Thewet process, which was once standard, has now been rendered obsolete by the development of efficient dry grinding equipment, and all moderncementplants use the dryprocessWhen it is ready to enter the kiln, the dry raw mix has 85% of the particles less than 90 £gm in size [2]
Dec 13, 2018· The wet process, on the other hand, is free from the dust, grinding is easier and the composition of the cement can easily be controlled. Wet Process The specific feature of the wet process is that the raw materials are prepared in water whereas in the …
Manufacture Process of Cement. The manufacture procedures of Portland cement is described below. Mixing of raw material; Burning; Grinding; Storage and packaging; 1. Mixing of raw material. The major raw materials used in the manufacture of cement are Calcium, Silicon, Iron and Aluminum.
Wet process Mixing of Raw materials in wash mill with 35 to 50% water. Materials exiting the mill are called “slurry” and have flow-ability characteristics. Size of the kiln needed for manufacturing of cement is bigger. Raw material can be mixed easily, so a better homogeneous material can be obtained

The total consumption of coal in this method is only about 100 kg when compared to the requirement of about 220 kg for producing a ton ofcementin thewet process. The dry material undergoes a series of chemical reactions in the hottest part of the kiln and some 20 to 30 percent of the material becomes liquid, and lime, silica and alumina ...
If we consider the Quality and Rate thenwet processis better and if we consider Fuel consumption and Time ofProcessthen dryprocessis better. * DryProcessThe both calcareous and argillaceous raw materials are firstly crushed in the gyratory...
Apr 03, 2020· Thecementmanufacturingprocessinvolves several key steps, including preparing the raw materials, grinding the materials together, heating the newly formed clinker in a kiln, and finishing thecementwith fine grinding.Some of the main ingredients used to makecementinclude limestone, clay, shale, iron, and sand.Different manufacturing techniques will use eitherwetor dry grinding, but ...
Cement-Cement-Extraction and processing: Raw materials employed in the manufacture ofcementare extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. Some deposits are mined by underground methods. ... In thewet processthe slurry tanks are stirred by ...
Thecementis now ready for transport to ready-mixconcretecompanies to be used in a variety of construction projects. Although the dryprocessis the most modern and popular way to manufacturecement, some kilns in the United States use awet process.

Dry mixprocessandwetmixprocessare the two methods of shotcrete construction which are based on the time at which the water is added to the mortar or Shotcrete is a type ofconcreteor mortar mix that is shot onto a surface at high-speed. The shotcreteprocesscan be performed in two ways, either using a dry mix or by means of awetmix.
At present PortlandCementis manufactured by two processes, DryProcess, andWet Process. The main difference between these two methods of manufacturing ofcementis that in the dryprocess, calcareous and argillaceous raw materials are fed into the burning kilns in a perfectly dry state.
