Auto Screw Feeder

We are reckoned name of the market for manufacturing and exporting a wide range of Auto Screw Feeder in Zhengzhou, Henan, China.
FB screw feeder is a kind of measuring equipment for feeding control, dynamic measuring and continuous conveying bulk material and powder. It can be widely used in building materials, chemical, coal, ports, ceramics, food, and other industries.
The screw feeder has two types:single tube single layer and double tube, double layer. If it is the former, it can realize measurement and conveying at the same time. If it is the latter, the above undertakes steady flow and conveying, and the bottom undertakes measurement and conveying that can have better steady flow effect and save spaces. Besides, the lenghth of the conveyor can be designed according to actual conditions.

Working principle:
When material is conveyed through screw from inlet to outlet, the material weight can be detected by the lode cell on the electrical weighing device under the conveyor and a signal in proportion to the material weight will be generated and transmitted to the controller. Meanwhile, the speed can be detected by the speed sensor installed on the tail pulley and a signal is also generated and transmitted to the controller. By multiplying the weight signal and the speed signal, the instantaneous flow value and total accumulation can be calculated.
