Screw weighing feeder is a production metering equipment for continuous conveying, dynamic metering and control of feeding of powder and granular parts. According to the process requirements, the flow and flow direction control of the materials passing through the screw conveyor are carried out, and the metering management is realized. Widely used in electric power, metallurgy, coal, chemical, port, building materials and other industries. Equipment composition: scale body, deceleration motor, weighing sensor, speed measurement sensor, control system and frequency conversion speed regulation system. Working principle: The screw weighing quantitative feeder is used for the quantitative feeding of scattered materials, the feeding process is spiral rotating continuous feeding, the feeder will come from the material delivery of the user feeding bin or other feeding equipment and carry out weight measurement through the weighing bridge frame; the speed measurement of the spiral body is carried out by the speed measuring sensor installed at the end of the machine; the measured weight signal and the speed signal are sent together to the 3000B/6000B weighing controller for calculus processing, showing the instantaneous flow and the accumulated amount. System Features: Sealing structure to reduce dust spreading The combination of dynamic metering and screw conveying materials The frequency conversion speed regulation is stable and reliable (optional) Electronic automatic measurement calibration coefficient, automatic zero adjustment dynamic zero nonlinear output characteristic tracking Digital Pulse Generator to provide reliable and accurate speed signals Technical parameters: Static measurement error:≤0.5%; Dynamic cumulative error:≤1%; Control accuracy: better than 1%; Instrument power supply: single phase 220V±10%,50HZ; Drag power: three phase 380V ±10%,50HZ; Use environment: Temperature:-10°C~50°C Humidity:5% to 90% no condensation
