How Is Cement Produced in Cement Plants

Cement plants are usually built near the quarry of limestone so the quarried limestone can be transported to the cement plant directly by belt conveyor or other conveying systems If the distance between the quarry and the cement plant is too long to use conveyors the limestones will have to be transported by trucks which means higher transportation fees and inconvenience
