    04/05/2020· During the cement production process, these minerals are fused together by heating them to just under their melting point, forming a cement clinker between 3 to 20 mm in diameter Pure cement is formed when the cement clinker is ground into a fine powder To regulate how cement mortar or concrete will set, gypsum is added to this powder Gypsum is a mineral consisting of hydrated calciumThe clinker progresses through the cooler by moving moreorless horizontally along the grate, and so the direction of the cooling air is roughly at right angles to the direction of movement of the clinker, and the cooler functions as a crosscurrent heat exchanger This mechanism is inherently less efficient than a countercurrent heat exchanger such as a rotary or planetary cooler, but thereCement Kilns: Grate CoolersFrom the kiln, the clinker goes to the clinker cooler The cooled clinker is then transported by a pan conveyor to the clinker silo for storage The clinker cooling can recover up to 30% of heat from the kiln system, preserves the ideal product qualities, and enables the cooled clinker to be transported by conveyors Air sent through the clinker to): Automation solutions for the Cement Industry
