Selection of rotary kiln process

Cement rotary kiln is a very important and more commonly used equipment for rotary kiln. It is mainly used for calcining cement clinker, dry production of cement rotary kiln and wet production of cement rotary kiln. Metallurgical chemical rotary kiln is mainly used for metallurgical industry iron and steel plant iron ore calcination; chromium, nickel ore oxidation roasting; refractory plant roasting high alumina bauxite and aluminum plant roasting clinker, aluminum hydroxide; chemical plant roasting chromium Ore and chrome ore powder and other minerals. Lime rotary kiln (ie activated lime rotary kiln) for roasting steel plants, ferroalloy plant with active lime and light burning dolomite.

Rotary kilns are divided into two forms. The first is by structure can be divided into horizontal rotary kiln and vertical rotary kiln; the second is by production type can be divided into wet rotary kiln and dry rotary kiln, which wet rotary kiln is mainly used for wet production In the cement kiln called wet rotary kiln, wet production is the raw material made of water for about 35 percent of the slurry, due to the preparation of a fluid with a mud, so the raw materials mixed between the good material composition is uniform, rotary kiln burning clinker high quality, which is the main advantages of wet production. And wet rotary kiln is different, dry rotary kiln and wet rotary kiln compared to the advantages and disadvantages of the opposite. Dry rotary kiln is made of raw material dry powder, moisture is generally less than one percent, so it is less than the wet method to reduce the heat required to evaporate moisture. Hollow rotary kiln because the exhaust gas temperature is high, so heat is not low. Dry production of raw materials made of dry powder, the liquidity is worse than the mud. So the raw material mixture is not good, the composition is not uniform. Therefore, the most popular or wet rotary kiln.
