Wet Process of Cement Manufacturing Cement Wet

Wet Process The wet process of cement manufacturing refers to grinding raw material into slurry after mixing with water and then feeding them into the wet process kiln for drying and calcination and finally forming clinker The slurry’s water content is usually between 32%36% 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 the semiwet process, which still belongs to the cement wet

What is the cement clinker? As we know, the cement production process is mainly divided into raw material preparation, clinker calcination, and cement grinding Clinker is the material produced in the calcination stage and is usually used as the binder in many cement products In other words, it is a semifinished cement product by preparing limestone, clay, iron raw materials, etc, in proper proportion,

Control of cement clinker production in a wet process

Cement clinker is produced by sintering a raw material, such as limestone mixed with silica alumina and ferrous or ferrique oxide, that is homogenized and fed into a rotary kiln The production may take place using a dry, semiwet, or wet process, where the type of process refers to the amount of water added to the raw material In the dry process, dried limestone, the raw material, passes through a series of

Cement kiln Wikipedia

By 1950, a typical large, wet process kiln, fitted with dryingzone heat exchangers, was 33 x 120 m in size, made 680 tonnes per day, and used about 025–030 tonnes of coal fuel for every tonne of clinker produced Before the energy crisis of the 1970s put an end to new wetprocess installations, kilns as large as 58 x 225 m in size were making 3000 tonnes per day

This wet process is advantageous due to the increased compatibility with wet climates and more uniform blending of raw materials prior to the kiln, along with lower kiln dust emissions However, a disadvantage to the wet process is that it requires more energy to produce clinker See also [http://wwwepagov/epaoswer/other/ckd/rtc/chap2pdf] for more information about the wet process

Cement – Analysis IEA

Clinker is the main ingredient in cement, and the amount used is directly proportional to the CO 2 emissions generated in cement manufacturing, due to both the combustion of fuels and the decomposition of limestone in the clinker production process From 2014 to 2018, the clinkertocement ratio increased at an average of 16% per year, reaching an estimated 070 in 2018; this rise was the main reason for the increase in direct CO 2 intensity of cement production
