The rotary valve is also called the ash discharge valve. It uses the rotating impeller with the compartment to transfer the powdery and small granular materials from the upper silo or the hopper to the lower discharge port to achieve uniform feeding or shifting. material. With the speed control motor, the impeller speed can be adjusted and changed at any time as needed to achieve the adjustment of the feed amount.

Rotary valve is mainly used in dust removal, cleaning and packaging machines and professional conveying and batching systems in power plants, cement industry, chemical factory etc.  as a gas lock or dosing for conveying dry powdery materials, and also for dust collectors. The ash ash from the air preheater is used in the conveying system of powder (powder, granule material, powder mixture) for discharging, metering, dust removal, quantitative transportation, mixing and packaging.

Rotary valve is widely used for nuts, almond, sunflower seed, cotton seed, grain cereals, chestnut, coffee, grain, sugar, spice, cement, calcite, glass powder, marble powder, plastic pellets, sawdust, coal etc.

1. Simple structure, convenient to use and maintain, the temperature of the material to be conveyed can be 0~300 °
2. You can remotely controlled the speed of rotary valve through inverter which is easy to change the feeding amount.
3. With the change of physical properties of material and the different storage of materials in the separator or dryer, the discharge amount changes little.
4. It has a certain air tightness, and the rotation speed is slow, and it will hardly cause damage to materials.

The rotary valve rotates an impeller with an aliquot structure in the housing through the transmission of the motor and the reducer, and fills the cavity of the impeller from the material of the upper silo or the feeding device of the housing, and the material rotates with the impeller Discharge to the lower part of the housing. The feeding and unloading can be uniformly and continuously quantified according to the requirements of the conveying system.
