3 Classification and model representation
3.1 Classification
Vertical countercurrent cooler particles depending on structure type discharge mechanism into vertical reciprocating grid nesting particles countercurrent cooler and swing
Type discharge flap vertical countercurrent cooler particles.
3.1.1 Reciprocating vertical grid nesting particles countercurrent cooler
Reciprocating vertical grid nesting countercurrent cooler particles mainly from the feed air is closed, all feeders, cooling cylinder, reciprocating raster discharge device,
Material level, discharge hopper, frame and other components. The device requires additional configuration network includes cooling air suction duct, cyclones and fans. work
As the pellet feed motion from top to bottom, bottom-up forced flow of air through the pellets to get cool and lower humidity. Cooled
After the feed is discharged from the discharge device reciprocating the grid.
3.1.2 Vertical swing flap discharge particles countercurrent cooler
Swing flap discharge vertical countercurrent cooler particles mainly from the feed air is closed, all feeders, cooling cabinet, swinging flap discharge device,
Material level, discharge hopper, frame and other components. The device requires additional configuration network includes cooling air suction duct, cyclones and fans. work
As the pellet feed motion from top to bottom, bottom-up forced flow of cooling air through the pellets to get cool and lower humidity. through
The cooled pellets discharged from the swing flap discharge device.
