Counterflow cooler is a pellet cooler, commonly used in pellet production lines, to cool the hot pellets extruded from the pellet mill. Cooled pellets have a smoother and harder surface and are less likely to break during shipping and handling.
Counterflow Cooler Working Principle
The counterflow cooler is a relatively advanced new cooler in the world at present. It uses the principle of countercurrent cooling to cool the pellets with high temperature and high humidity.
The ambient wind passes through the pellets vertically, and the gradually heated hot air contacts the hot pellets. The direction of the wind flow is opposite to the flow direction of the pellets, so that the pellets are gradually cooled in the forward direction, which can avoid the sudden cooling of the pellets caused by the direct contact between the cold wind and the high-temperature pellets. pellets surface cracking.
The air enters the cooler in all directions from the bottom, the air inlet area is large, the utilization rate is high, the energy consumption is low, the operation is simple, and the cooling effect is remarkable.
