Introduction:
FB screw
feederis 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**1A intelligent
controller is adopted
2. Compact structure&steady operation
3. Automatically calibrate and measure system zero
4. With the function of self-diagnosis and can be connected to DCS
system
5. set all kinds of parameters by hand.
6. Gravimetric weighing combined with screw convey to realize
continuous dynamic measuring.
