Working Principle and Performance of Star unloader

Star unloader is the mainly ash discharge equipment for stockpile, feedstock, quantitative feeding, pneumatic conveying and dust removal equipment system. In general, it is consist of rotor wheel with blades, casing, sealing, reducer and motor etc.
Working principle : when the star unloader works, the dust dropsinto the valve by gravity, thenfills the star blade on the top and side fully. The blade rotor rotates together with the reducer rotate shaft which is driven by motor, the dust will be discharged by self-gravity.
The outlet of bag dust collector and cyclone dust collectorshould be equipped with rotary valves, to discharge the dust into the dust collector hopper and ensure the air tightness of the whole dust collector system. Rotary valve is the most advanced discharge device in china, usually can be used as one of the most important equipment in dust collector system. It specially used for dust and small granular material in environmental protection, metallurgy, chemical, grain, cement, build road, drying equipment etc industries.
