Manufacturing Portland Cement The basic ingredients of both the dry and wet processes are the same By mass, lime and silica make up approximately 85% of portland cement The materials that are commonly used are limestone, shells, chalk, shale, clay, slate, silica sand, and iron ore
Dry process These are two different processes of manufacturing cement wet process minerals are wet ground (by adding water) to form a slurry and then dried, dry process minerals are dry ground to form a powder like substanceBoth the processes are in use and have their own advantages and disadvantagesWhile in wet process grinding is easier,in dry process there is a saving in fuel costs
Types of Cement Processes • Wet Process • Dry Process - 74% of cement produced • Preheater/Precalciner Process 16 Evolution of the cement Process • Wet process easiest to control chemistry & better for moist raw materials • Wet process high fuel requirements - fuel needed to evaporate 30+% slurry water
Cement Manufacturing Process Phase 1: Raw Material Extraction Cement uses raw materials that cover calcium, silicon, iron and aluminum Such raw materials are limestone, clay and sand
In the dry process these mixes are stored in silos; slurry tanks are used in the wet process Thorough mixing of the dry materials in the silos is ensured by agitation …
