The invention discloses a dual-section conveyor for a clean concentrated feed or compound feed. A first through groove for supplying air and a second through groove for exhausting air are formed in the back side of a cabinet body of a control cabinet; a screen mesh and a fan are erected in the first through groove for supplying air; a plurality of partition plates arranged at equal distance are erected in the second through groove for exhausting air; a ditch way matched with a locating piece connected with a driving motor is arranged on the back side inside the cabinet body of the control cabinet; guide grooves in mirror image distribution are erected on the top and bottom walls in the cabinet body of the control cabinet, and the position of each guide groove correspond to that of the ditch way; the locating piece is erected between a pair of guide grooves through a guide block; and the bottom wall of the locating piece is connected with a fan with a starting and stopping switch through a connecting rod. The defect that a driving motor assembly is damaged because the cooling performance is poor and particulate matter impurities fly into the control cabinet in the prior art is avoided.
