We know, dry process rotary kiln and kiln wet compared advantages and disadvantages of the opposite. Dry raw materials can be made of raw powder, water is typically less than 1%, so it is more than wet reducing evaporation of water needed to heat. Hollow kiln exhaust gas due to high temperature, so the heat consumption is low. Dry process for the production of raw materials can be made of dry powder, its mobility than mud difference. The raw material is not well mixed, uneven components.

Mainly used for calcining cement clinker, divided dry process cement rotary kiln and wet process cement rotary kiln two groups. Metallurgy and chemical rotary kiln is used for metallurgical industry iron and steel factory lean iron ore magnetizing roasting; chromium, nickel iron ore oxidation roasting of refractory material factory; baking high-alumina mine and smelter roasting clinkers, aluminum hydroxide; chemical plant baking chrome ore and chrome ore powder and other minerals. Lime rotary kiln (active lime rotary kiln for calcining ) iron and steel plant, ferroalloy plant with active lime and dolomite.
