Key factors in setting up a cement plant

Before starting to build a cement plant, it is imperative to know what the cement making process involves. The cement manufacturing process starts with mining of limestone followed by grinding it with other raw materials like clay, shale, bauxite, iron ore, etc. to prepare a raw meal, which is heated at a sintering temperature of 1,400 to 1,500 degree Celsius in a kiln to manufacture clinker.
