Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, and in particular to a probability feeding screen. Background Technology

[0002] The working principle of a probability screen is mainly based on the movement of materials on the screen surface and the relative motion between particles. When the material enters the screen surface, it is subjected to the excitation force generated by the vibrator, causing the material to jump and tumble on the screen surface. During this process, particles collide and rub against each other, causing smaller particles to fall through the screen mesh into the lower layer, while larger particles remain on the screen surface to continue to be screened.

This method is relatively troublesome to install and disassemble, and it is time-consuming to replace the screen. During long-term operation, high-frequency vibration may also cause the nuts to loosen, resulting in the screen becoming loose.
