Cement manufacturing process description
Quarrying
twain types of naturals ar necessary for the production of cement: one abounding in calcium or calcareous materials such as limestone, chalk, etc., and one that is rich in silica or clayey materials such as clay. Extensive objective drilling and compend are creation undertaken to rivet the variability of the mad material quality. The quality check that starts from the quarry ensures optimization in the use of the reserves. Limestone and clay are either scraped or blasted from the quarry and then transported to the crusher.
Crushing
The crusher is responsible for the primary size reduction of the quarried materials. Boulders as big as 1 meter are being crushed to material sizes less than 80 mm.
Pre-blending
The crushed materials snick through an on-line analyzer to determine the pile composition. A stacker is then used to create different piles of materials and to reduce variation in material beds.
Raw grinding and blending
A belt conveyor transports the pre-blended piles into individual bins where a weighing feeder proportions it according to the type of clinker to be produced.
The materials are then ground into the desired fineness by the raw mill equipment.
The powdered raw meal is then transported into a continuous blending storage silo where variations are further cut back by mixing using aeration.
Burning and clinker cooling
The homogenise raw mix is fed into the pre-heater, a heat convince equipment composed of a series of cyclones wherein heat transfer amid the raw mix feed and the counter current zealous gases from the kiln take place. Calcination partially takes place in the preheater. Raw meal is fed directly from the preheater to the rotary kiln. The slight angle of purpose and rotation of the kiln causes the raw feed to slowly make its carriage through the kiln counter current to the...If you want to get a full essay, order it on our website: Orderessay
