Description

Technical Field

[0002] Vibration screening device is a screening equipment, which achieves the purpose of screening by applying vibration to the screen body to loosen, layer and screen the materials. This equipment can also be used for dehydration and desludging. The working principle of the vibration screen is mainly to make the screen surface produce complex rotation vibration through the reciprocating vibration generated by oscillation excitation, so that materials with different particle sizes pass through a single or multi-layer screen surface with uniform holes to achieve screening. Particles larger than the screen holes remain on the screen surface, and particles smaller than the screen holes pass through the screen holes, completing the screening process.
