Application Field:

Hot selling FB variable screw feederis a kind of measuringequipment forfeeding control, dynamic measuring and continuous conveying bulk material and powder.It can be widely used inbuilding materials, chemical, coal, ports, ceramics, food,and other industries.

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 adopted.

2.Gravimetric weighing combined with screw convey to realize continuous dynamic measuring.

3. Compact structure&steady operation.

4. Automatically calibrate and measure system zero.

5.Set all kinds of parameters by hand.

6. With the function of self-diagnosis and can be connected to DCS system.

7. single tube single layer and double tube double layer can be chosed.
