旋转供料器又称星形给料器，锁气器，关风器等。通常的旋转供料器结构及工作原理是由带有数个叶子的转子的圆筒型机壳内旋转、将上部料斗中的物料通过叶子片空间旋转输送到下部卸出。而对于风力输送（压送式、吸送式）系统，只需旋转供料器即完成上述卸料功能，又不使高压气体通过供料器泄漏到上部料仓，影响物料的下落。因此该旋转供料器是气力输送系统中的重要组成部件，它可以均匀而连续地向输料管中定量供料，从而完成物料的输送。而在系统的分离收尘部，它又可以作为卸料器的功能。

　　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.

　　设备适用于具有磨耗性粉粒体的物料,机壳内设有可更换的衬套,用来延长使用寿命,转子用高硬度合金堆焊,衬套镀硬铬。广泛应用于电厂脱硫,粉煤灰输送,水泥建材、码头吸卸、拌合站等行业。外形尺寸与其它性能与普通碳钢旋转供料器一致。

　　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.
