Pellet ring cooler is one of the main equipment in the process flow of grate-rotary kiln – ring cooler in the pellet engineering, which is used to cool pelletized ore discharged from the rotary kiln at about 1200℃ and recover the residual heat, finally the pelletized ore is suitable for transportation.
The pellet ore ~ 1200℃ removed from the rotary kiln is uniformly distributed on the platform assembled in the frame of the trolley by fixed screen and feeding hopper. The air blower installed in the lower part of the frame is used for air blowing. The sealing cover device on the upper part of the frame is used for waste heat recovery. The pin gear of the driving device exerts torque on the frame of the trolley with pin teeth to make the frame rotate at a constant speed. The pellet is cooled to the required temperature at the discharge area. At this time, the trolley reverses the discharging and resets, and the cooling operation is completed under the limitation of the curving track. After unloading and resetting in the discharging area, the trolley can continue the cooling operation of the next cycle.
The waste heat recovery device of the sealing cover on the upper part of the frame is operated. The pin gear of the driving device exerts torque on the frame with pin teeth to make the frame rotate uniformly. When the mining area is unloaded, the pellet cooling reaches the required temperature. At this time, the trolley will automatically turn over and discharge, reset and cool under the restriction of the curved track. After unloading and reset in the unloading area, the trolley will continue the cooling operation in the next cycle.
Our company has the mainstream specification products of pellet ring cooler, and the 248 ㎡ pellet annular cooler manufactured for Longteng, Zhanjiang is the largest specification produced by our company, which was put into operation in February 2008.
