Introduction:
WFL/M belt weigh feeder is a perfect equipment for continuous weighing, feeding and dosing of bulk material and powder, and can also realize open-loop and closed loop flow control.We have two models: WFL, WFM. It can be widely used in building materials, chemicals, coal, ports, ceramics, food, fertilizer, and other industries.

System extensibility:
1.Can chose star-shaped, disc type pre-feeding device for achieving well-distributed feeding.
2.Can be equipped with material blockage alarm to make you find blockage in time and remove them as soon as possible.
3.According to actual conditions, different hopper and shield can be chosen:
4.Can achieve open-loop control.
5.Open, partial open, full closed out casing can be chosen.
6.It can be designed and manufactured according to the special requirements.
Features:
1. Reliable electrical weighing device: unique structure and reliable weighing.
2. EB-DAS2000 control system, SPL-F microcomputer centralized control system, PLC control system are optical.
3. Unique deviation- resisting technique ensures the belt operate well.
4. Belt of different width, thickness, environment suitability can be chosen according to specific process requirements.
5. Unique spillage-proof device.
6. Unique belt tightening and aligning device.
7. Unique scraping device to protect belt and make the system operate well.
8. Sophisticated weighing system, no operation friction and with little maintenance.
9. Installation load cell is treated specially to protect the load cell and ensure stable and reliable long-term operation.
10. High accuracy speed measuring device is the effective guarantee for system measurement.
11.Unique electrical automatic calibration, captive chain calibration, and weights-hoist calibration.

Working Principle:
The working principle of belt conveyor is installed the Electrical weighing device under the belt, when the material works on the load cell which can generate a signal in proportion to the material weight and the signal is transmitted to the controller. At the same time, the speed sensor installed on the tail pulley detects the belt speed and generates a signal which is also transmitted to the controller. By multiplying the weight signal and the speed signal, the instantaneous flow rate and total accumulation can be calculated.
