Technical Field

[0001] The utility model relates to the technical field of compound fertilizer production, in particular to a screening device for compound fertilizer production. Background Art

[0002] Compound fertilizer refers to a fertilizer containing two or more nutrients including nitrogen, phosphorus and potassium. During the production process of compound fertilizer, it is necessary to use a screening device to screen it in order to separate particles of different particle sizes in the compound fertilizer raw materials to ensure that the particle size in the fertilizer is uniform.

[0003] The existing screening device for compound fertilizer is mainly composed of a drum screen and a power mechanism. When the compound fertilizer is screened, the drum screen is rotated by the power mechanism, thereby achieving the purpose of screening.
