The invention relates to the technical field of compound fertilizer processing, in particular to a high tower granulation compound fertilizer screening device which comprises a screening barrel, a material control unit and a screening mechanism. According to the compound fertilizer screening device, after compound fertilizer falls into the screening mechanism, the compound fertilizer makes contact with the three screening plates in sequence from top to bottom, the three screening plates with the screening holes of different hole diameters screen the compound fertilizer in sequence through operation of the vibration set, and compound fertilizer particles of different sizes are separated; and the compound fertilizers with different particle sizes fall out through different discharging pipelines, the operation process of screening and separate placement of the compound fertilizers with various sizes is completed, the screening requirement is met, the screening effect is improved, an inclined strip corresponding to each screening plate drives a cleaning strip on the inclined strip to intermittently clean the corresponding screening plate, and the screening efficiency is improved. In conclusion, multiple times of screening operation of different hole diameters and intermittent cleaning of different screening plates are achieved, and blocking is prevented.
