Cement Rotary Kiln Introduction:
Rotary Kiln belongs to building material equipment, according to different
materials, which can be divided into cement kiln, metallurgy
chemical kiln and lime kiln. Cement kiln is used for making cement
clinker and there are dry and wet methods to make cement clinker.
Metallurgy chemical kiln is widely used for magnetic roasting of
poor iron ore and oxidizing roasting of chrome and nickel in the
steel factory; backing high-alumina mine in the refractory material
factory; baking chamotte and alumina in the aluminum factory and
baking chrome ore and chrome powder in the chemical plant. The Lime
Kiln is used for roasting active lime in steel works and ferroalloy
plants and light roasting dolomite.
Working Principle of Rotary Kiln:
The kiln is a cylindrical vessel, inclined slightly to the
horizontal, which is rotated slowly around its axis. The material
to be processed is fed into the upper end of the cylinder. As the
kiln rotates, the materials gradually move 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 burner. The fuel may be gas, oil or
pulverized coal.
