旋轉供料器又稱星形給料器，鎖氣器，關風器等。通常的旋轉供料器結構及工作原理是由帶有數個葉子的轉子的圓筒型機殼內旋轉、將上部料斗中的物料通過葉子片空間旋轉輸送到下部卸出。而對于風力輸送（壓送式、吸送式）系統，只需旋轉供料器即完成上述卸料功能，又不使高壓氣體通過供料器泄漏到上部料倉，影響物料的下落。因此該旋轉供料器是氣力輸送系統中的重要組成部件，它可以均勻而連續地向輸料管中定量供料，從而完成物料的輸送。而在系統的分離收塵部，它又可以作為卸料器的功能。

　　Rotating feeder, also known as star feeder, air lock, air shut-off device, etc. The typical structure and working principle of a rotary feeder is that it rotates inside a cylindrical casing with a rotor with several leaves, and transports the material from the upper hopper to the lower part through the space of the leaves for unloading. For wind powered conveying (pressure feeding, suction feeding) systems, simply rotate the feeder to complete the above unloading function, without allowing high-pressure gas to leak into the upper material bin through the feeder, affecting the material's fall. Therefore, the rotary feeder is an important component of the pneumatic conveying system, which can uniformly and continuously supply a certain amount of material to the conveying pipe, thus completing the conveying of materials. And in the separation and dust collection section of the system, it can also function as an unloader.

　　設備適用于具有磨耗性粉粒體的物料,機殼內設有可更換的襯套,用來延長使用壽命,轉子用高硬度合金堆焊,襯套鍍硬鉻。廣泛應用于電廠脫硫,粉煤灰輸送,水泥建材、碼頭吸卸、拌合站等行業。外形尺寸與其它性能與普通碳鋼旋轉供料器一致。

　　The equipment is suitable for materials with abrasive powder particles. The casing is equipped with replaceable bushings to extend the service life. The rotor is welded with high hardness alloy, and the bushings are plated with hard chromium. Widely used in power plant desulfurization, fly ash transportation, cement building materials, dock suction and unloading, mixing stations and other industries. The external dimensions and other performance are consistent with ordinary carbon steel rotary feeders.
