Cement Manufacturing Process Flow Chart

In the cement manufacturing process, most material must be broken, such as limestone, iron ore, clay and coal etc. Limestone is the main raw material for cement production, each producing a ton of clinker needs about 1.3 tons of limestone, more than 80% of raw material is limestone.
