in the cement industry, in cases where the raw material chemical composition varies greatly. Prehomogenisation is used primarily for the main components in cement production, i.e. limestone and clay. With the increasing variation in the grades of coal used for coal firing installations, there is a growing need for prehomogenisation and storage of
Aug 30, 2012· Generally cement plants are fixed where the quarry of limestone is near bye. This saves the extra fuel cost and makes cement somehow economical. Raw materials are extracted from the quarry and by means of conveyor belt material is transported to the cement plant. There are also various other raw materials used for cement manufacturing.

Cement production processes can be categorized as dry, semidry, semiwet, and wet processes depending on the handling of raw material before being fed to the rotary kiln. Nowadays, almost all new plants are based on the dry process and many old wet plants are also remodeled to .
Most new cement plant is of this type. The principle is similar to that of the dry process preheater system 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

The plant first produced cement in 1967 as Ideal Cement. Now the plant produces multiple types of cements which are then used in the production of concrete. Moreover, the Seattle plant produces about 600,000 tons of various cements each year. Production is mostly sold in Washington State and Oregon.

Cement industry is not a water polluting industry. Only the cooling tower blowdown associated with the GCT is a source of waste water generation, which does not have much significance as a water pollutant. The waste water is treated in septic tanks or sewage treatment plants and is used for gardening, irrigation and other purposes.
Emissions can vary considerably from plant to plant and according to cement plant processes. Carbon dioxide (CO2) emissions are primarily from the calcination of limestone and combustion of fuel in the kiln. Average CO2 emissions from calcination are 553 kg/metric ton .
