Description

Technical Field

[0001] The utility model belongs to the technical field of feed processing, in particular to a grading and screening device used for feed processing. Background Art

[0002] Grading and screening equipment for feed processing: It is a mechanical equipment used to grade feed raw materials according to different standards such as particle size, shape and quality. Its main function is to classify the particles in the raw materials according to the set size standards through the screening process, so as to ensure that the final feed produced has a uniform particle size to meet the nutritional needs of different animals.

[0003] Most of the grading and screening equipment currently used in feed processing uses multiple transmission devices to vibrate the screen plate during grading and screening, resulting in inconsistent vibration effects, which in turn causes incomplete screening or uneven particle distribution. In addition, when the feed is vibrated and screened, the dust in the feed will be excited and suspended around the screening plate, causing the dust to settle on the screen surface and block the screen aperture, thereby reducing the screen aperture and affecting the screening results.

[0004] To this end, we provide a grading and screening device for feed processing to solve the above problems. Utility Model Content
