The energy crisis in the 1970’s accelerated the development of the dry process which today is used in almost all modern cement plants.
These are two different processes of manufacturing cementWet process minerals are wet ground by adding water to form a slurry and then dried dry process minerals are dry ground to form a powder like substanceBoth the processes are in use and have their own advantages and disadvantages.
Aug 30 2012 cement manufacturing process phase 1 raw material extractionCement uses raw materials that cover calcium silicon iron and aluminumSuch raw materials are limestone clay and sandIt is combined with much smaller proportions of sand and clay.
Cement manufacturing process is mainly divided into three stages namely raw meal preparation clinker burning and cement grindingGenerally speaking the cement industry production is portland cementPortland cement is a kind of delicate usually gray powder which consists of calcium from limestone silicate aluminate and ferrite clay.
The dry process for the manufacture of cement is preferred only in places where hard crystalline limestone and shales are availableThe only advantage of this process is that the fuel consumption is low.

Feb 24 2021 dry cement powderThe cement manufacturing process involves several key steps including preparing the raw materials grinding the materials together heating the newly formed clinker in a kiln and finishing the cement with fine grinding.
In the dry process the materials are grounded mixed and introduced into the kiln system in a dry stateIn the wet process the raw materials follow all of the steps with water added and are introduced into the kiln system in a slurry state.
In these animated video you can see wet and dry process in cement manufacturing and another video about cement production’s simulation at one of cement factories.
It is worthy when considering the amount of cementThe 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 recombine.
