Introduction:    FB  Grain screw conveyor 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. The control system compares the actual flow signal with the

set flow signal and then regulates the output signal through PID to adjust the feeding speed dynamically

and thus to realize the continuous feeding.Product Features:1. FB-DMC-01A intelligent controller is adopted2. Compact structure&steady operation3. Automatically calibrate and measure system zero4. With the function of self-diagnosis and can be connected to DCS system5. set all kinds of parameters by hand.6. Gravimetric weighing combined with screw convey to realize continuous dynamic measuring.Parameters:Weighing accuracy: ±1%Conveying capacity: 1~100t/h
