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. 3.2 Vertical countercurrent cooler particle model representation KL □ - □ ④ ⑤ ① product variety Code. feed pellets cooler. ② Product Type Code.
