V-type electromagnetic vibrating feeder is widely used in light industry, chemical industry, food processing, commerce and other industries. It is used in the production process of feeding, batching and quantitative automatic packaging of powder and granular materials, and can realize centralized control and Automatic control, compared with other types of feeders, has the characteristics of small size, light weight, simple structure, low power consumption, and stepless adjustment of the feeding amount. Equipped with an automatic amplitude-stabilizing control box of the electromagnetic vibrating feeder, which can make it not affected by the fluctuation of the power supply volt. Age and improve the feeding accuracy.
