1. Rotary kiln
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.
Working principle:
The rotary 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.

2. Vertical kiln
Working principle of vertical shaft kiln:
The raw material to be calcined is charged at the top of the kiln. It it then pre-heated by the combustion gases in the counter-current before reaching the burning zone. In the burning zone the material is calcined by means of fuel introduced together with primary combustion air through radially arranged burner lances. Cooling air is introduced at the discharge part of the kiln to cool the product in a counter-current manner. The heated cooling air travels upwards to the burning zone and is used again there as the secondary combustion air.
From the top of the kiln he exhaust gas are directed to a dust collecting system.
Main features of small quicklime shaft kiln production line plant:
1. A Wide range of product reactivity, due to easy adjustability of operating temperatures
2. Large stone size range
3. High flexibility in adjusting the burning zone temperature
4. Low impurity level in the product, e.g. sulphur or fluorine
5. Suitable for gaseous, liquid and solid fuels
