Main features: This series steady stream of powder dosing screw is a powder material conveying, weighing measurement and dosing control as a whole, mechatronics patented product; can be applied to a variety of industrial powder materials production environment continuous measurement and dosing control system; the use of a number of advanced technology, reliable operation, high precision control; can be widely used in building materials, metallurgy, electric power, chemical industry, powder material measurement technology links. Equipment consists of: system consists steady flow feed screw, metering screw conveyor, drive, load sensors, speed sensors and electronic control system. Features: 1, the feed screw has a unique steady flow structure over the entire cross section of the inlet feed powder evenly sink, easy to knot arch, easy red material; 2, steady flow metering screw feeder screw and synchronous speed, steady flow of material feed screw filling factor of 1.0, 0.6 metering screw material filling factor, the largest output range units (1:10) when adjusted weight signal true, high accuracy; 3, helical blade material selection manganese steel precision production, wear resistance and long service life; 4, a small spiral gap and overcome red material reflux problems and avoid gaps in the wall adhesion material; 5, sealing structure, reduce dust published.
