Arrange the steps in sequence for manufacture of cement in dry process.
Arrange the steps in sequence for manufacture of cement in dry process.
The correct option is A 2413
Explanation for the correct option -
(A) In the dry process, limestone and clay are mixed together to achieve the desired mixture and the following sequence is followed
(2) Pulverization - Here the mixture of clay and limestone is subjected to a pulverizer and a fine powder is obtained.
(4) Heating to high temperature - The mixture of limestone and clay is then heated to a high temperature of
(1) Formation of clinker - After heating to high temperature the mixture is converted to clinkers. Clinkers are hard nodules-type structures obtained after heating.
(3) Addition of gypsum - The clinkers are then mixed with gypsum (a hydrated form of plaster of Paris) to make them more strong.
Hence option ‘A’ is the correct choice for the sequence of steps that occurs in the manufacture of cement in the dry process.
