The Use, Scope of Application and Features
1.1   The Use and Scope of Application
The cooling of granules is an indispensible process of pelletizing section. The temp of granules from pellet mill can be reduced from 70℃——90℃ to just 3℃ to 5℃ higher than the ambient temperature by using reverse-flow cooler, and to the required water moisture(≤12.50℃) for the convenience of pellet transport, storage and reserve.
1.2   Features
As of now, the reverse-flow cooler, as one of the latest coolers prevailing across the globe, avails itself of the counter flow cooling theory to refrigerate granules with high temp and moisture, namely, when vertically passing through the bed of material, the cold air will sweep through cold material. And then the increasingly warm-up air will diffuse together with hot material yet the air direction is opposite to the material flow, hence, granules will be cooled gradually and forwardly lest other coolers directly shock-chill the high-temp material and the surface of granules thereby crazes. Because the cold air goes into the cooler in all direction covering large area and in high-use, therefore, the cooling effect is outstanding. Also, thanks to its low energy consumption and convenient operation, this type of cooler precedes over even updated vertical and horizontal types.
Both the upper and lower level detector mounted on the door will automatically control cooling time and discharge pellets.
