The new technologically advanced plant is based on a dry process producing about 4,000 tons of clinker a day, for a total of about 1.5 million tons of concrete per year. It is one of the biggest plants of this type working in Europe. The revamping made the plant efficient and in compliance with the best environmental protection techniques.
Cement Manufacturing Process. the last stage of making cement is the final grinding process. in the cement plant, there are rotating drums fitted with steel balls. clinker, after being cooled, is transferred to these rotating drums and ground into such a fine powder that each pound of it contains 150 billion grains. this powder is the final.
Cement grinding cement packing and storage 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, than 80 of raw material is limestone.
