High efficiency professional twin shaft lime kilns manufacturer

Double shaft kiln is called as PFR kiln(double shaft parallel flow regenerative lime kiln ).Xinhua double shaft kiln possesses the unique advantages of very low energy consumption and uniform calcination of lime. To realize the above functions, Xinhua double shaft kiln is of special external shape and unique production process. the illustration about Xinhua double shaft kilnXinhua double shaft kiln possesses two shafts loaded with limestone and there are connection channels in the junction area of cooling zone and calcination zone of each shaft.Double shaft kiln alternately durings the two cycle period and illustrate the preheating zone, calcination zone and cooling zone.In the cycle period 1, combustion air enters into the top of shaft 1 and gets mixed with fuel in calcination zone, then they flow downwards to the channel and are discharged from the top of shaft 2.Cooling air enters into the bottom of each shaft and unites with the air flow for combusting coal gas, then be discharged from shaft 2. In the cycle period 2, combustion air and fuel enter into shaft 2, then flow downward to channel and be discharged from shaft 1.2.
