Abstract

The star powder feeder is one of the most widely used in today's society machine, it is widely used in food production, cement processing, smelting metal, building materials processing and other fields, is a very wide range of applications of a technology. It is used in powder or granular materials the automatic intermittent or continuous measurement (dosing), such as activated carbon, PVC particles, carbon black, titanium dioxide, pigments, cement, sand, soda, urea, tungsten powder, alumina powder, flour, food additives, and so on. Widely used in water treatment, fine chemicals. Pesticide ore, building materials, food industry, feed and so on. This article describes a spiral dosing machine. It combines the powder conveying, weighing measurement and quantification of feeding control, mechanical and electrical integration products; powdered materials for a variety of industrial production environment continuous metering and ingredients control system; typical decency mainly by the steady flow to the feed screw The metering screw conveyors, inverter, load sensors, speed sensors and electronic control systems. And describes the structure and composition, working principle, characteristics and applications. The entire system is designed for the the powder feeding process material leakage, shed positions defects reasonably practicable structure.
