Rotary Air Lock Valve is a type of rotary feeder which provide feeder and metering functionality of a standard rotary feeder. The main function of a rotary valve is to control the flow from one chamber to another and maintaining a good airlock condition. The product is in dry powder or granular form. Moreover, Rotary Air Lock Valve is used in a wide range of applications where there is a need to reduce system air losses while transferring material between tubes with differing pressures.
Typical materials include:
- Fly ash
Rotary Airlock Valves Are A Type Of Rotary Feeder And Are Often Referred To Simply As A Rotary Airlock Or Rotary Valve. They Provide Feeding And Metering Functionality Of A Standard Rotary Feeder But Their Primary Duty Is To Maintain Pressure And Provide An Optimal Airlock Seal Between Different Product Conveying Transitions, Such As Gravity To Pneumatic Conveying Lines.
The Design Includes An Impeller Which Is Mounted Directly Onto The Gearbox Shaft And An End Plate Mounted Bearing With Lip Seals On The Non-Driven Side. The Inlet Ports Have “V’S” Cast Into The Side Wall To Create A Scissor Cutting Action Between Impeller Blade And Casing. This Ensures Smooth Rotation Without The “Chopping Effect” Experienced With Other Valves. The Result Is Increased Bearing And Impeller Tip Life.
Rotary Airlock Feeders Have Wide Application In Industry Wherever Dry Free-Flowing Powders, Granules, Crystals, Or Pellets Are Used. Typical Materials Include: Cement, Ore, Sugar, Minerals, Grains, Plastics, Dust, Fly Ash, Flour, Gypsum, Lime, Coffee, Cereals, Pharmaceuticals, Etc
