The rotary feeder itself does not include the core component of "metal compensator"; The two are independently installed components with different functions in the pneumatic conveying system: the rotary feeder is responsible for quantitatively locking the air feeding, and the metal compensator (usually referring to the corrugated compensator) is responsible for absorbing the thermal displacement and vibration of the pipeline. ‌‌　　Our company specializes in the production of (B) GFY, YJD series air shut-off fans (air shut-off devices), star shaped unloaders, DS series electric air locks, DN type rotary valves, quick opening cleaning valves, anti jamming rotary valves, offset anti jamming, air delivery straight through rotary valves, high temperature and high pressure rotary valves, high temperature water-cooled, scraper self-cleaning, titanium alloy ceramic tungsten carbide PTFE PTFE nylon polyurethane, arch breaking machines, silo scraper crushers, fragmentation valves, screw conveyors and other products.
