How to choose the rotary kiln process

Cement rotary kiln is a very important and more commonly used equipment for rotary kiln. It is mainly used for calcination cement clinker, dry production of cement rotary kiln and wet production of cement rotary kiln. Metallurgical chemical rotary kiln is mainly used for mine iron ore calcination of metallurgical industry iron and steel plant; 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) is used for roasting active lime and light burning dolomite of steel plants, ferroalloy plant.

Rotary kilns process 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 process rotary kiln and dry process rotary kiln, which wet process rotary kiln is mainly used for wet production in the cement kiln called wet process 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 calcination clinker has high quality, which is the main advantages of wet production.

Compared to wet process rotary kiln, dry process rotary kiln has opposite advantages and disadvantages. Dry process 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 is wet process rotary kiln.
