     · The quarried raw material is then transported to the cement plant, using mechanical conveying equipment such as ropeways or belt conveyors, or by vehicles like wagons and trucks. The quarried limestone is normally in the form of big boulders, ranging from a few inches to meters in size. These varying sizes of limestone need to be crushed to a size of about 10 mm in order to be prepared .
