Rotary valve (commonly known as rotary feeder or star feeder) is a special equipment used for unloading, packaging, mixing, dedusting, metering and quantitative transportation in the conveying system of solid materials (powder, granular materials and powder mixture). The working principle is to rotate an impeller with an equally divided structure in the shell through the transmission of the motor and the reducer. The materials from the upper bin of the shell or the feeding device are filled in the cavity of the impeller, and the materials are discharged from the lower part of the shell with the rotation of the impeller. The material can be discharged to the downstream uniformly and continuously according to the requirements of the conveying system.

旋轉(zhuǎn)給料器已獲得六項(xiàng)，并被上海市列入高新技術(shù)成果轉(zhuǎn)化項(xiàng)目。

The rotary feeder has obtained six national patents and has been listed in the high-tech achievement transformation project of Shanghai.
