There are two differentprocessesformanufacturing cement.wet process mineralsarewet ground(by addingwater) to form a slurry and thendried,dry process mineralsaredry groundto form a powder-like substance. Both theprocessesare in use and have their own advantages and disadvantages.
A rotary kiln is a device that supplies tremendous amounts of heat in order to change the chemical composition of an object.
Cement rotary kiln is the main equipment of calcining the cement clinker. The characteristics of a rotary kiln are simple structure, convenient and reliable control of the producing process.
The hammer crusher, also named heavy hammer crusher, crushes by the collisions between high-speed hammer and materials. It has features of simple structure, high reduction ration, high efficiency, etc.
Sand maker is suitable for the crushing of soft, hard and extremely hard material and reshape of those products.
Hongxing rod grinder is especially suitable for crushing river gravel to make sand. It's a kind of effective and energy saving rod grinding machine.
In the metallurgical industry, shaker table is mineral processing equipment used for sorting fine material.

The kiln has to operate continuously in order to ensure a steady regime, and therefore uniformity of clinker. 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 todry processand semidry process.
The wet process of cement manufacturing involves adding water to finely crushed raw material, such as limestone, clay oriron ore, in a proportion of 35 to 50 percent water to 50 to 65 percent raw material to make a slurry that is fed into a cement kiln, whereas no water is added in the dry process.

Dec 13, 2018· The specific feature of thewet processis that the raw materials are prepared in water whereas in thedry processthe materials are ground and mixeddry. The flowsheet diagram of thewet processformanufacturingPortlandcementis given in Figure 3.3.
Atcementplant, according to different raw materials preparation methods,cement manufacturingcan be divided into thedry process(including semi-dry process) andwet process(including semi-wet process). Next, we will discuss thewet processofcement manufacturingin details.
Other articles whereDry processis discussed:cement: Manufacture ofcement: …are known as thewet,dry, and semidry processes and are so termed when the raw materials are groundwetand fed to the kiln as a slurry, grounddryand fed as adrypowder, or grounddry…
Thedry processconsumes much less fuel as the materials are already in adrystate, whereas in thewet processthe slurry contains about 35 to 50 percent water. In a recent trend, the majority ofcementfactories are using thedry processofcement manufacturing.
Indryand semidryprocesses formanufacturingofcement, the raw materials are crushed and fed in the correct proportions into a grinding mill. The raw materials are dried and reduced in size to a fine powder in to grinding mill. Thedrypowder is called the raw meal. The raw meal is pumped into a blending silo.
Thewet processofcement manufacturinginvolves adding water to finely crushed raw material such as limestone clay or iron ore in a proportion of 35 to 50 percent water to 50 to 65 percent raw material to make a slurry that is fed into acementkiln whereas no water is added in thedry process.

Methodsof Manufacturing ProcessofCement. At present PortlandCementis manufactured by two processes,Dry Process, andWet Process. The main difference between these two methodsof manufacturingofcementis that in thedry process, calcareous and argillaceous raw materials are fed into the burning kilns in a perfectlydrystate.

Portland cementcan be made by following two different processes – adryone and awetone. Joseph Aspdin first madeportland cementin his kitchen stove in England in the 19th century. Lime and silica make up approximately 85% ofportland cement. The materials that are commonly used are limestone, shells, chalk, shale, clay, slate, silica sand, and iron ore.
Aug 27, 2015· Theprocessis accordingly known as thedry processor thewet processof mixing.Dry process(modern technology) In thisprocess, the raw materials are first reduced in size of about 25mm in crushers. A current ofdryair is then passed over these dried materials. These materials are then pulverized into fine powder in ball mills and tube mills.
whereas thedry cement processconsumes 3609.75 MJ/ ton. The high energy consumption of thewet processover thedrycan be attributed to the mix preparation method adopted prior to burning of clinker in the kiln (water being added to the raw materials to form raw thick slurry), whereas thedry processis only based on the preparation of fine powdered raw meal by grinding raw material followed ...
