Product Description

Machine introduction  

 

A Rotary kiln is a pyroprocessing device used to raise materials to a high temperature (800-1350℃ 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.

 

Hongji lime kiln is used to produce quicklime through the calcination of limestone (calcium carbonate). The chemical equation for this reaction is

 

    CaCO3 + heat → CaO + CO2 

 

This reaction takes place at 900 °C (at which temperature the partial pressure of CO2 is 1 atmosphere), but a temperature around 1000 °C (at which temperature the partial pressure of CO2 is 3.8 atmospheres[1]) is usually used to make the reaction proceed quickly.[2] Excessive temperature is avoided because it produces unreactive, "dead-burned" lime.

 

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.

 

 

Structure

The basic components of a rotary kiln are the shell, the refractory lining, support tyres and rollers, drive gear and internal heat exchangers.
