Description

Technical Field

[0001] This utility model belongs to the field of fertilizer processing technology, specifically a screening device for fertilizer processing. Background Technology

[0002] During fertilizer production and processing, the produced fertilizer products easily absorb moisture from the air and clump together. To ensure the high quality of the fertilizer products, they need to be finely screened to remove clumps and ensure that the fertilizer particles are uniform. Screening is generally carried out using a screening device.

[0003] Existing fertilizer screening devices typically involve agitating the fertilizer product, forcing granular fertilizer through a screen while trapping lumps, to perform screening. However, this process results in fertilizer products becoming mixed together, leading to low screening efficiency and potential screen clogging. Furthermore, fertilizer particles between the agitator blades and the device's inner wall are easily crushed due to compression, turning into powder and resulting in poor-quality screened fertilizer. Therefore, we provide a fertilizer processing screening device to address these problems. Utility Model Content
