[0002] A screening device is a device used to separate and extract specific particles or substances. It can selectively separate particles according to their size, shape, density, color or other characteristics. A vibration screening device is a device that uses vibration for screening. It allows the material to be subjected to vibration force in a specific direction, causing the material to move up and down and form a multi-angle throwing motion, and uses the mechanical, frictional and collision effects between particles for screening. This device is suitable for granular materials and has a good cleaning effect on defects such as mud, mud attachments, impurities, foreign matter, etc. in the materials. The vibration screening device can be used in material recovery equipment, ceramics, paint, food and other industries.
