Cement Manufacturing Process
Part One: Raw Material Preparation. General. The production of cement is started from quarrying the raw material. The main raw materials are limestone, basalt, sand stone, pumice, gypsum. Site Exploration of suitable deposits, for the raw material has three main aims:-. Verifying the quality of the raw materials.
BASIC CEMENT PLANT LAYOUT
The major raw material for cement production is limestone. The limestone most suitable for cement production must have some ingredients in specified quantities i.e., calcium carbonates, silica, alumina, iron, etc. Typically, cement plant locations are based upon the availability of good quality limestone in the vicinity.
