Commonly known as rotary kiln, it is also called rotary dryer, belonging to construction equipment. Depending on the materials, the rotary kiln falls into three types: clinker rotary kiln, limestone rotary kiln and cement rotary kiln.
Commonly known as the rotary kiln, the rotary calcining kiln is also called the rotary dryer, belonging to construction equipment. Depending on the materials, the rotary kiln falls into three types: clinker rotary kiln, limestone rotary kiln and cement rotary kiln.
The cement rotary kiln is mainly used for calcining cement clinker, divided into the dry method production equipment and the wet type production equipment. Clinker rotary kiln is widely used in steel works in the metallurgy industry for magnetizing roasting of poor iron ore ; oxidizing roasting of chromium and nickel iron ore; roasting high aluminum vanadium and soil ore pellets in refractory plants; roasting clinker and aluminum hydroxide in aluminum manufacturers and roasting chrome ore and powder in chemical plants . The limestone rotary kiln (i.e. the active lime kiln) is used for roasting active lime in steel works and ferroalloy plants and light roasting dolomite.
The cement rotary kilns mainly fall into two types: one is horizontal cylinder device (also called the rotary kiln) with gradient; the other is vertical without rotation (also called the shaft kiln).
The cement rotary kiln used in wet type production, which produces slurry with water content of 32%-40% from raw materials, is called the wet type rotary kiln. Due to the liquidity of the slurry, the raw materials are sufficiently mixed, making clinker of high quality, which is the main advantage of wet production.
Contrary to the wet type production, the dry type cement rotary kiln makes raw materials into dry powder with water content less than 1%, thus reducing the heat needed for water evaporation. Hollow type cement rorary kiln has high consumption of heat because the exhaust flue gas is of high temperature. The fluidity of dry power is worse than that of the slurry.
The materials to be burnt get into the stove from the higher end of the cylinder. Due to the slope and slow rotation of the cylinder, the material moves around from top to bottom along the axis to finish its process. At last, the finished materials get into the cooler through the burner hood. The fuel gets into the kiln through the head of the kiln. The waste gas will be discharged from the end of the kiln after exchanging heat with the materials.
