ZW series self-centering feeder is a new type of feeding equipment developed by our engineers with advanced technology and optimized design. A pair of bearings is installed on the transmission assembly and the machine body is supported by spring seats. When the shaft and eccentric mass are rotating, the machine body will vibrate in an oval track. Its working principle is that the eccentric inertia vibration of the pulley and countershaft generates a regular stroke and thus provides automatic feeding through vibration. https://www.crushermachine.net/c...en/vibrating-feeder.html
