My company engineering and technical personnel to fully absorb and learn from Germany, Japan, Denmark and other countries produce similar products, combined with a novel based on the design and development company design and production of other types of powder given material set experience The powder dosing equipment. Uniform feed material from the feed inlet rotor scale, the fulcrum of the scale body of the rotor scale and expected out on the same axis and flexible connection with the outside world, is in equilibrium. Powder into the the PWF rotor scale from the imports from the rotor to the discharge port and chic into the lower-level device. Material deviation from the process of moving the bearing axis, that is, a moment load cell measured the reaction forces on the axis. Because the arm to a fixed value, so the size of the force and the rotor is proportional to the weight of materials. The signal and the rotor speed signal by the control system processing operations, the actual flow of the powder, adjust the speed of the rotor, powder dosing. RF Series powder feeder is separated by surge plates and separators into by the feed chamber, the pressure chamber, measuring chamber of three parts. To enter the chamber by feeding the powder under stirring leaves by surge plates into the mouth of the pressure chamber blanking pressure cavity by mixing the regulator to a certain degree of density partition off the discharge port into the metering chamber. Multiple separate compartments in the measurement chamber, the powder material to certain plotting in these sub-grid evenly distributed through the rotation of the rotor may set the volume way for the material, that control the motor speed can change the feeding ability.  

  

Features:1. Be applied for dynamically and continuously feeding and measuring the jet-like material or non jet-like material and powdery material.2. The feeder integrates feeding with weighing, adjusting and conveying.3. Feed-forward control, high accuracy and low fluctuation.4. It can not only eliminate the differential pressure caused by  pneumatic transmission and material feeding, but also transmit the coal from coal bunker to bunker. It Is a feeding control device integrating quantitative feeding with conveying with high accuracy.5. Permanent gravimetric weighing operation and reliable operation. Discharge directly from the storage bin without a feeding control device before the rotor weigh feeder.6. Lower the fluctuation of coall feeding and reduce the excess air so as not to increase CO when discharge the gas.7. Because the rotor weigh feeder and the compress air system are integrated as a whole, so the rotary valve and screw pump are saved.8. The pressure changes of the compressed air system do not influence the accuracy so the measuring accuracy is high.9. The rotor weigh feeder structure is compact so as to save space; the building area is small so as to reduce the capital investment.10. Can bear 1 Mpa pressure and is explosion-proof.11. The whole design is composite structure. It is easy to maintain the rotor. The wear parts can be quickly replaced without special tool and lifting equipment.12. Adopt special material, service time is extended, maintenance reduced, investment saved and operation rate improved.13. 32 bit microcomputer is used as the main control device of electronic control part; touch screen is adopted as human-computer interface; frequency converter is mainly used as the control component. All of make our product offer high technology.Parameter:Weighing Range: 0~50t/hWeighing Accuracy: ±0.5%
