Zusammenfassung:The invention relates to a preparation method of high-concentration compound fertilizer, in particular to a drying device after granulation of the high-concentration compound fertilizer. The device comprises a base, a vertical drying bin, a built-in rotation mechanism and a rotary shifting mechanism; the built-in rotation mechanism comprises a rotation cylinder and a driven frustum; and the rotary shifting mechanism comprises an oscillating cylinder, a rotary shaft and a plurality of shifting frames. Pelleted compound fertilizer particles are dried in a mode of combining stacking drying and rotary drying, a step-by-step drying mode is adopted, the whole device adopts a vertical distribution design, the structural design is compact, the occupied field space area is small, and the drying effect and the drying efficiency can be greatly improved on the premise that drying sufficiency and effectiveness are guaranteed in the preparation and drying processes of the high-concentration compound fertilizer. 本发明涉及一种高浓度复
