Discription of rotary kiln

Can be divided into cement kiln, metallurgy chemical kiln and lime kiln according to different materials

Cement kiln is used for making of cement clinker and there are dry and wet methods to make cement

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, baking chamotte and alumina in the aluminum factory and baking chrome ore and chrome powder in the chemical plant

Structure Features of Rotary Kiln: 

The kiln shell is made of rolled steel plates; its structure is optimized by computer software, and features" 

longitudinal flexible and transverse rigid", which improved the loading of supporting device and stability of 

refractory lining,  

The supporting roller bearings features smaller width over diameter ratio L/D, leading to its higher reliability.

The special high-started torque motor for cement industry rotary kiln is applied for driving system. The 

sealing of labyrinth plus spring pressing with asbestos heat isolation layers attached, is applied higher so that

reliability and longer service life of sealing are achieved.

Application of Rotary Kiln:

1. Rotary kiln is commonly used in the production process of catalytic agent, molecular sieve and zinc oxide, 

etc.As a result, you can find a rotary kiln in variety of industries, like steel annealing and nonferrous smelting 

industries, metallurgy and chemistry fields, and building industries, and more.

2. Rotary kiln system, which is also called a rotary calcine kiln, is a commonly used building material machine.

 Classifying by material properties, a rotary kiln falls into cement kilns, metallurgy chemical kilns, and lime kilns.

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.
