Product Description

Lime rotary kiln

 

The rotary kilns produced by our company can be used for chemical industry, lime industry and etc. Through technical renovations, the rotary kiln sintering system equipment made by our company has adopted high measuring precession plunger pump, variable speed adjusted valve, contact graphite block air seal and other national advanced technologies .In order to raise up automation degree, industrial TV has been used at the kiln head for monitoring of kiln , analog fluorescent screen has been used for display of process flow; infrared scanning system has been adopted for sintering zone to directly reflect the burning conditions on the computer. With the use of these new technologies ,it is directly in vision, convenient in operation and reliable in use .Therefore ,the rmalcondition can be raised . Compared to been raised 3~5% up, production has been increased 5~*0% and heat consumption has been reduced *5% down.

 

Then the Lime chemical industry kiln mainly uses in the Lime profession iron and steel plant poor iron ore magnetization roasting;Chromium,josephinite oxidizing roasting; The refractory materials plant roasts smelts the gold ore and the aluminum manufacturer roasting chamotte , the aluminum hydroxide high; Chemical plant roasting chromium ore and chromium powdered ore mineral of the same kind.



Structure Features of Lime 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 reliabilit

 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.

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.
