  Counter-flow cooler is newly developed and most advanced pellet cooling equipment. It is mainly used for high temperature pellets cooling after granulation.

The pellets discharged from the pellet mill are of high temperature and moisture. They are fed by a closed air feeder at the top of the cooler. Then the rotating distribution structure disperses the feed evenly in the cooling cabinet. The air blower sucks hot air from the top feed part, while the cold air enters the cooler from the bottom in all directions and pierce into the feed vertically to take away the heat and moisture. Cooling air reverse the pellets and the pellet is cooled from the bottom to top gradually, thus the cooling time is increased, which does good to the production of high quality pellets and to extend the time of pellets storage. Cooling time is controlled by material upper and lower level. When material reaching upper level, the motor is turn on, beginning discharging. But when material lower than lower level, the motor is stopped, stopping discharging. To avoid overflow, the cooler has been provided with an overflow sensor, which stops feeding to the cooler. The pendulum counter-flow cooler is composed of a closed air feeder, air exhaust header, upper and lower feeders, hydraulic controlling system, pendulum flap discharging system and air sucking system, etc.
