1. Introduction

Rotary Kiln is a pyroprocessing device used to raise materials to a high temperature (calcination) in a continuous process. Materials produced using rotary kilns Include:

  Cement

  Lime

  Refractories

  Metakaolin

  Titanium dioxide

  Alumina

  Vermiculite

  Iron ore pellets

They are Also used for roasting a wide variety of sulfide ores prior to metal Extraction.

  

Rotary Kiln is widely used for many industries like metallurgy, chemical industry, building Refractory materials, environmental protection, etc. the Rotary Kiln consists of cylindrical shell, supporting device, supporting device of thrust roller, Driving unit, moveable kiln head, sealing device on the tail of kiln, coal dust Pipe device, etc. the kiln body has a certain tilt angle with level. the whole Kiln body is supported by the roller supporting device, and it is also equipped with thrust roller device to control the up and down movement of the kiln body.

 

 

 

2. Advantage

(1). New Type technology is adopted by main driving system. Compared with traditional Magnetic and DC speed regulation, its main driving system has the advantages like energy saving, environmental, wide speeding adjusting range, high Performance and stable operation.

(2). after the welding of bases for supporting devices of supporting roller and catching Roller, vibration aging treatment should be applied for remove the welding Stress. Then, use vertical lathe and boring-milling machine for integration Fabrication. this process can guarantee the requirement of fabrication Precision and dimension & location tolerance. Installation accuracy of Rotary kiln is obviously improved.

(3). Temperature measuring point is reserved at bearing base of supporting roller. It is mainly used for automation detection of kiln operation status by insert the measuring device.

 

 

 

3. Working Principle

the kiln Is a cylindrical vessel, inclined slightly to the horizontal, which is rotated Slowly about its axis. the material to be processed is fed into the upper end of the cylinder. as the kiln rotates, material gradually moves 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 bunsen burner. the fuel for this may be Gas, oil, pulverized petroleum coke or pulverized coal.
