Description

Technical Field

[0001] The utility model relates to the technical field of solid feed additive processing, in particular to a screening device for solid feed additives. Background Art

[0002] Feed additives are substances added in small or trace amounts during feed production, processing, and use. They are used in small amounts but have significant effects. They are essential ingredients in the modern feed industry, and they have significant effects on enhancing the nutritional value of basic feed, improving animal performance, ensuring animal health, saving feed costs, and improving the quality of livestock products.

[0003] Chinese patent publication number CN210279758U discloses a screening and impurity removal device for feed additives. The device comprises a base, wherein the upper ends of the base are fixedly connected to the bottom ends of a support plate via a support rod, and the top ends of the support plate are fixedly connected to the bottom ends of a screening box via a shock absorber. The bottom of the screening box has a tapered discharge port. A support ring is fixedly mounted on the inner wall of the cylindrical portion of the screening box, and a fixed block is fixedly mounted on the outer wall of the screening box. A J-shaped rod is slidably mounted on the fixed block. A limit block is welded to the long end of the J-shaped rod below the fixed block. The upper surface of the limit block is fixedly connected to the bottom surface of the fixed block via a spring.
