A wide variety of cost of cement plant options are available to you, such as free samples. There are 4,252 cost of cement plant suppliers, mainly located in Asia.
In presence of moisture, cement undergoes chemical reaction termed as hydration. Once the hydration process has taken place, cement becomes useless. Cement can remain in good condition as long as it does not come in contact with moisture. Moisture is a big enemy of cement and hence cement bags never stored for a long period.
Summary of production process. The material formed in the kiln is described as 'clinker' and is typically composed of rounded nodules between 1mm and 25mm across. After cooling, the clinker may be stored temporarily in a clinker store, or it may pass directly to the cement mill. The cement mill grinds the clinker to a fine powder.

CEMENT (Data in thousand metric tons unless otherwise noted) Domestic Production and Use: Production of portland cement in 2017 in the United States increased slightly to about million tons, and output of masonry cement was stagnant at million tons. Cement was produced at 98 plants in 34 States, plus at 2 plants in Puerto Rico.
In the cement production line, producing 1 ton of Cement need grind at least 3 tons of materials (including raw materials, fuel, clinker, mixed materials,gypsum).Grinding operation consumes about 60% of total power in cement plants, raw material grinding more than 30%, while coal mill used in cement plant consumes 3%, cement grinding about 40%.
Cement manufacturing brief description of a cement mill. Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum .
(4) This type of mill can crush materials which are too large to be fed into the tube (ball) mill. (5) Ground materials are dried by the flue gas from the kiln. Schematic process flow of vertical roller mill for grinding of raw materials. Vertical roller mills are adopted in 20 cement plants (44 mills) in Japan.

Dry Process for Manufacturing of Cement. The fused mass turns fuses into balls of diameter 3 to 25 mm known as clinker. The clinker drops into coolers where it is cooled under control condition. Cooled clinker and 3 to 5 percent of gypsum are ground in ball mill to required fineness and then taken it to storage silos from where the cement is bagged.
