[0002] Vibrating feeder, also known as vibration feeder, is a commonly used material conveying and feeding equipment, widely used in mining, coal and other industries. Vibrating feeder conveys materials from storage bins or hoppers to the next processing equipment or system through vibration force. The exciting force generated by the vibration motor causes the vibrating body to vibrate continuously, thereby pushing the material to the conveying trough to achieve continuous material transportation. In ore beneficiation, vibrating feeding equipment is often used to evenly transport the ore to be beneficiated into the beneficiation equipment. In the process of vibrating feeding and conveying of some beneficiation, the ore needs to be initially screened and conveyed according to the specifications.
