introduction of Rotary kiln
Rotary kiln belongs to building material equipment, which can be divided into cement kiln, metallurgy chemical kiln and lime kiln according to different materials.Rotary kiln(cement kiln) is used for making of cement clinker and there are dry and wet methods to make cement. Rotary kiln (metallurgy chemical) kiln is used for magnetic roasting of iron ore and oxidizing roasting of chrome and nickel in the steel factory; baking high-alumina mine in the refractory material factory; baking chamotte and alumina in the aluminium factory and baking chrome ore and chrome powder in the chemical plant.Rotary kiln (lime kilnis) used for baking active lime and dolomite in the steel factory and ferroalloy factory.
Working principle
The kiln is a cylindrical vessel, inclined slightly to the horizontal, which is rotated slowly about its axis. The material to be processed is fed into the upper end of the cylinder. As the kiln rotates, material gradually moves down towards the lower end, and may undergo a certain amount of stirring and mixing. Hot gases pass along the kiln, sometimes in the same direction as the process material (co-current), but usually in the opposite direction (counter-current). The hot gases may be generated in an external furnace, or may be generated by a flame inside the kiln. Such a flame is projected from a burner-pipe (or "firing pipe") which acts like a large bunsen burner. The fuel for this may be gas, oil, pulverized petroleum coke or pulverized coal.
Types of rotary kiln
Cement kiln;
Metallurgy chemical kiln;
Active lime kiln;
Porcelain kiln according;
Building material kiln;
Calcined petroleum coke rotary kiln.
Application of rotay kiln:
Rotary kiln is mainly used for metallurgy, building materials, ores and other mineral materials, heating and calcining. Such as ceramic sand, bauxite, limestone, cement, fly ash magnesium aluminum hydroxide, aluminum products, alumina refractory materials such as mineral particles and the heating and calcined powder
Advantages of rotary kiln:
High productivity;
Low heat consumption;
Stable clinker quality;
High ecomomic efficiency.
