Self-contained filter element and fan, filter element built-in back-blown mechanism to prevent plugging filter element, set up two sets of filters to make the feeding station cavity maintain micro-negative pressure, prevent dust when feeding; To solve the problem of dust emission during feeding process, dust free feeding is realized. Auxiliary flow aid can be selected to prevent material sticking and bridging. The vibrating screen can be configured to filter some impurities in the material.
