旋转给料阀（俗称旋转给料器或星型给料器），是应用于固体物料（粉沫、颗粒物料、粉粒混合物）输送系统中用来卸料、包装、混合、除尘、计量、定量输送的设备。工作原理是通过电机、减速机的传动将一个带有等分结构的叶轮在壳体内旋转，从壳体上部料仓或给料装置的物料填充在叶轮的型腔内，物料随叶轮的旋转到壳体的下部卸出。可以按照输送系统的要求均匀地、连续不断地向下游卸料。
Rotary valve is called rotating feeder or star sharp feeder.This special equipment is applicable for unloading,packing,mixing,dedusting,metering,rationing conveying of solid materials powder,particles and its mixtures）conveying system.The working principle is,by driving motor and reduction gears to turn equi-divided structure impeller inside the shell,then materials from upper silo of the shell or feeder are filled inside cavity of impeller,where materials are discharged along with impeller rotating to the bottom of shell.Materials can be discharged equably and continuously to the downstream unit according to the conveying system requirements.
