Small Vertical Preheater / Vertical Preheater for Dolomite Rotary Kiln
Vertical Preheater Description:
Preheater is polygonal vertical structure, and composed of the top bin, feeding tube, heater body, hydraulic pushing device, transfer chute, etc. The top material bin is equipped with a material level controller to control the material layer height; limestone move into the vertical preheater through sliding tube between top bin and preheater body and have the effect of sealing to prevent the cold air into the preheater for active lime processing plant.
Vertical Preheater Principle:
After the limestone enter the preheater, about 1100℃ high temperature waste gas discharged from sintering kiln flow into the preheater moving towards the opposite direction. By the sufficient heat exchange, the materials can be uniform preheating. The temperature of limestone after preheated can reach 900℃, about 30% of the limestone will be decomposed. The temperature of discharged gas is less than 220℃, which shorten the time of sintering and lower the heat consumption and fuel cost, and effectively reduce the production cost. After preheating, limestone is pushed into the kiln by hydraulic push rod, the waste gas after heat exchange, will be discharged into atmosphere after processing by the dust collector. The advantages of the vertical preheater are good preheating performance, fewer moving parts and reliable operation.
Vertical Preheater Advantage:
1.Easy to start.
2.Reduce engine wear.
3.Environmental protection.
