Rotary Kiln refers to rotating calcination kiln, belongs to construction material equipment. According to different materials, rotary kiln can be divided into cement kiln, metallurgy chemical kiln and lime kiln. 

The cement kiln is used for makeing cement clinker and there are dry and wet methods to make cement. Metallurgy chemical kiln is applied in metallurgy industries and ironworks for lean iron ore, chromium ore and ferronickel ore calcination. Lime kiln is mainly used for calcine dolomite and active lime which is used in steel plant and ferroalloy factory.

Working Principle of Rotary Kiln:

1. With a certain slope to the level, the whole kiln body is supported by rollers and fitted with thrust rollers to control up and down movement of the kiln body.

2. Besides main driving unit for driving system, it is also fitted with the auxiliary driving unit so as to ensure the kiln body still can rotating when the main motor is powered off and prevent it from deforming.

3. The kiln head adopts housing type sealing and kiln rear uses axial contact sealing unit so that reliability of sealing could be ensured.

Features of Rotary Kiln:

Rotary kiln has simply structure, easy operation in producing, less wearing parts, high efficiency,it's used in the cement plant to calcine high grade cement, at the same time can be used in metallurgy,chemical,constructure ect. rotary kiln features in strong structure, stable operation, high-quality products from the kiln, and we can offers advanced efficient shaft preheater, five-grade cyclone preheater.
