Description

Technical Field

[0001] The utility model relates to the technical field of feed screening machines, in particular to a feed screening machine. Background Art

[0002] In order to ensure the quality of the finished feed pellets and improve market competitiveness, the processed and pelletized feed needs to be screened before the finished product is packaged, and the qualified feed pellets need to be subsequently bagged.

[0003] Most of the existing feed screening machines use vibrating screens for separation. During use, some fine particles and powder will float into the air, polluting the production environment. In addition, the vibrating screen vibrates violently and makes loud noises when working. The vibration will affect the overall structure of the screening device over a long period of use, reducing its service life. In addition, the vibration amplitude of the vibrating screen is small during the screening process, which causes the vibration of the feed particles to be small, causing some of the feed to accumulate on the screen, affecting the efficiency of feed screening. Therefore, a feed screening machine is proposed to solve the above problems. Utility Model Content
