Introduction
 
The rotary feeder  also known as electric discharge valve, star discharge valve, etc. It consists of motor, tooth differenced planetary gear speed reducer (X) or nylon needle cycloid speed reducer (Z) and turn the dragon tripper. 
It ofen applied to  non sticky dry fine powder or granular materials. Such as raw powder, cement, slag, coal powder, etc. Normally, they often installed in the following material library or ash bin. For block material, it can't be used due to the block material is easy to jam their impeller. 
It is designed for storage, feeding powder engineering, quantitative feeding, ash discharge in air and dust removal equipment system. Bag filter and cyclone exports have star discharger (or star discharging valve). Ash hopper will filter the dust and dust collection system in airtight. It is suitable for powdery and granular materials, for the environmental protection, metallurgy, chemical, food and other industrial departments extensiveapplication. 

 Features
1. Material: Carbon steel Q235, Stainless steel304, Stainless steel316
2.Optional input and output shape: circular input mouth, square input mouth
3. Both ends of the impeller are sealed with two and a half-PCE seal ring. So that the structure of the machine is simple and easy to installation and replacement.
4. Bearings at both ends are designed out of the body, so that it can reduce powder from entering into the bearing, it is a good way to reduce wear.
