Feeder is an economic and technical indicators advanced feeding equipment, and other feeding equipment compared with the following features: (1) small size, light weight, compact and simple structure; 2. Installation, easy maintenance, low operating costs; 3 high efficiency, the ability to feed; 4 low noise, improve the working environment; 5. low power consumption, high power factor; this device is far more than the resonance state, and thus the amplitude of stable and reliable operation of each kinds of materials strong adaptability; 7 structure is simple, uniform feeding, continuous performance, the exciting force adjustable; are subject to change and control the flow, easy to operate; eccentric block the excitation source, low noise, low power consumption, regulating performance, the phenomenon of red material; the use of a closed body prevents dust pollution stable vibration, reliable operation and long life; exciting force can be adjusted, subject to change and control the flow, easy to adjust stability; vibration motor as vibration source , low noise, low power consumption, good regulating performance, non-washed material phenomenon. Vibrating feeder structure is simple, easy to operate, do not need to Run, a small power consumption; can even adjust to the amount of ore; so widely used.
