Product Details
Product introduction
Introduction of rare earth rotary kiln

Regarded as industrial vitamin, rare earth has become a kind of very important strategic resource. Rare earth has been widely applied to petroleum, chemical industry, metallurgy, spinning, ceramics, glass, permanent magnet material and etc. with the development of technology and breakthrough of application technology, the value of rare earth oxide is increasing. In order to meet the demand of metallurgy production and separate rare earth oxide with other mineral materials, rare earth rotary kiln must be applied to the ore dressing and production of rare earth.
As a kind of precious mineral raw materials, rare earth is paid more and more attention. Rare earth has been processed by refinement, calcining, grinding and drying process step by step. Rare earth rotary kiln is a kind of important equipment to calcine rare earth. The final product holds good performance. Zhengzhou taida group will introduce you the working principle and structure in details.

Structure of rare earth rotary kiln

1.  Support device: rare earth rotary kiln adopts advanced main shaft structure. It is equipped with automatic temperature measuring device and electrical heating device.
2.  Catch wheel: it is divided into two kinds, mechanical and hydraulic catch wheel. Hydraulic catch wheel is equipped with advanced hydraulic control system.
3. Transmission device: rare earth rotary kiln is equipped with single transmission, double transmission, speed-adjustable motor, DC motor and variable-frequency motor to control rotary speed; it is reliable, energy-saving and efficient.
4.  Cylinder with base plate: there is fixed and adjustable base plate. it is characterized by simple structure, easy maintenance and simple repairement.
5. Seal device: there are many kinds of sealing forms which can be chosen according to different designs of rotary kiln. It is characterized by good adaptability and good seal performance.

Working principle

Materials in rare earth rotary kiln move from top to bottom. Volume shrinkage in the calcining process will make materials move. Or the dischargement of materials at lower part will lead to the movement of all materials in the rotary kiln. Therefore, the rotary speed of materials is mainly decided by the amount of materials discharged, namely the output capacity of rare earth rotary kiln. The rotary speed of rotary kiln must match with the calcining speed which is relevant to calcining temperature, air flow speed, heat transfer and material size. The movement speed of materials will change according to different situations. The movement of materials is always relevant to air discharged, rotary speed of rotary kiln, resistance in kiln, physical property of materials, kiln diameter and heat exchange device.


1.     The cylinder of rotary kiln is automatically welded by good calm carbon or alloy steel plate.
2.     The tyre, riding wheel and open gear adopt alloy cast steel materials.
3.     The sliding bearing of the equipment adopts special bearing with big gap.
4.     The transmission device of rare earth rotary kiln adopts reducer with hardened tooth surface, flexible diaphragm coupling and DC motor.
5.     Rare earth rotary kiln adopts hydraulic catch wheel.
