Design And Analysis Of Economical & Effective Drying System For Chemical Gypsum

Abstract

A cement plant requires fly-ash,gypsum and clinker as raw materials for production of cement. Gypsum is chemically written as \CaSO4· 2H2O". Different type of gypsum are available like mineral gypsum , synthetic gypsum and chemical gypsum. Mineral gypsum is a common mineral obtained from surface and underground deposits. Chemical gypsum is obtained as chemical waste from chemical plant. Gypsum is essential raw material for regulating the setting time. JK Lakshmi cement limited uses chemical gypsum as additive. Chemical gypsum is by product of chemical die plant. It contains high amount of moisture. It is causing problem in handling of gypsum. Plant needs system which remove moisture from gypsum and take it equal or below 10% w/w. Presently the plant use open drying but it is not helpful in all seasons and it consumes more time. Moreover, plant needs 80 ton/day gypsum. Hence, Plant requires economical and effective system for drying of chemical gypsum from all system.
