Brief on lime rotary kiln

 Lime Rotary Kiln’s Technical characteristics and process flow
  
1. Technical characteristics
  
The rotary kiln’s body adopts the high-quality carbon steel or alloy-steel plate, baton automatically finish all the possible weldings.
  
The tyre&roller and exposed gear all adopt alloy cast steel.
  
The sliding bearing uses bearings with excessive clearance and no bearing shoe grinding.
  
The gearing adopts hardened-gear speed reducer, flexible diaphragm coupling.
  
Adopting hydraulic block wheel.
  
Both the lime kiln head and the lime kiln end adopt pneumatic seals and scales overlying.
  
The lime rotary kilns are equipped with slow driving devices.
  
2. The Lime Rotary Kiln’s process flow is:
  
Feed the limestone and fuels into the lime kiln, after preheating up to 850?, the limestone and fuels begin to decompose, when the temperature reaches up to 1200?, calcination is complete. After cooling, the lime products will be sent out. This is the lime production . Different rotary kiln shapes have different ways of preheating, calcining and cooling. Although their process principles are the same, such as the raw materials quality, lime quality and consumption etc, these equipment values have a very great distinction.

Rotary kiln Tyre’s maintenance work
  
rotary kiln is a kind of heavy equipment , while working , frictional loss between tyre and the machine is large .If the machine works long hours under hard friction, it Will not only affect working efficiency, but also may result in reduce the rotary kiln’s life.In some way , in order to complete the maintenance, choosing superior lubricant can reduce enterprise’s lossesIncrease enterprise product production , which is an indispensable work for enterprise.
  
The following advices are provide by Henan Bailing machinery technology department .
  
1. choices of pressure additive
  
Due to its special process, the rotary kiln can not avoid from hard friction by using grease lubrication only . As the carrier , when the temperature is over 200 ?, the antirust grease’s evaporation loss will be serious , and its lubrication action can only lasts in a short time . So , choosing Solid lubricating material of full lubrication , heat resisting and anti-pressure is necessary . Solid lubricating material has good thermal stability , it has advantages of sending out heat.
  
2. choices of lubricating oil
  
The rotary kiln tyre works under great force and high temperature . Therefore, the machine has serious requirement on oil . Now , we choose synthetic lubricating oil as the carrier of HF-high temperature tyre lubricant , this kind of oil is lower than 100?, its viscosity is above 100 centistoke , and flash point is higher than 320?. At the same time , we choose composite high-temperature lubricate grease with dropping points more than 300?.
  
Actually , the choices of Rotary kiln Tyre’s maintenance work should based on practical situation , different types of rotary kiln equipment have different choices on lubricant , their maintenance also have different advantages and disadvantages . The above are only several methods , if you want more detailed information , please contact with our Website service , We wholeheartedly at your service.Rotary kiln is refer to rotate calcination kiln, belongs to construction material equipment. 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 in metallurgy industry and ironworks for lean iron ore, chromium ore and ferronickel ore calcination, which is used for calcining of high aluminum vandal ochre in refractory material industry; for calcining of calotte and aluminum hydroxide in aluminum manufacturer; for calcining of chrome sand ore and chrome powder ore in chemical plant. Lime kiln are used for calcine dolomite and active lime which is used in steel plant and ferroalloy factory.
