Dry process cement production kiln is the typical kiln type during the end of the 18th century and the beginning of the 19th century. It is a big step for haft kiln. Because of its less than 1% water content dust raw materials, it reduces the most needed heat for evaporating water. So, it needs less time than wet process cement production.
