產品介紹 Product introduction
旋轉給料閥(俗稱旋轉給料器或星型給料器)，是應用于固體物料（粉沫、顆粒物料、粉粒混合物）輸送系統中用來卸料、包裝、混合、除塵、計量、定量輸送的專用設備。工作原理是通過電機、減速機的傳動將一個帶有等分結構的葉輪在殼體內旋轉，從殼體上部料倉或給料裝置的物料填充在葉輪的型腔內，物料隨葉輪的旋轉到殼體的下部卸出?？梢园凑蛰斔拖到y的要求均勻地、連續不斷地向下游卸料。
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.
