Product Description

Application Field and Working Principle: FB weigh feeder is widely used to feed bulk material in the conveying system in coal,metallurgy,building material chemicals, etc. 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. Fetures: 1. Reliable electrical weighing device 2. Unique deviation-resisting technique ensure the belt operate well; 3. Installation of load cell istreated speciallyto protectthe load cell and ensure stable and reliable long-term operation; 4. High accuracy speed measuring device is the effective gurantee for system measurement; 5. Acording to the actual conditions, different hopper and shield can be chosen to achieve dust-proof, material cut-off and protective effect; 6. Can achieve open-loop and close-loop control; 7. Open, partial open,full closed out casing can be chosen; 8. High efficiency and energy conservation, low cost, unparalleled large capacity ; 9. Small volume, easy to install and replace, low cost on technical improvement; 10. It can be designed and manufactured according to the special requirement; Technical Parameters: Weighing accuracy ±0.5% Conveying capacity 1~1000t/h Belt width 500~1800mm Feeding distance ≥1500mm Speed range 0.01~1.5m/s Power range 0.37~10kw
