Rotary airlock valves are also called rotary feeders, rotary valves, or just rotary airlocks. is composed by 3 parts, electrical
machine, tooth differenced planetary gear speed reducer (X) or nylon needle cycloid speed reducer (Z) and dragon tripper.Used in both pressure style and vacuum style pneumatic conveying systems, these valves serve as a "lock" to prevent air loss while simultaneously performing vital material handling functions. Though simple, the rotary airlock valve is a critical component to the efficiency of a conveying system.
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.
Industries requiring this type include cement, asphalt, chemical, mining, plastics, food, etc.
Rotary feeders are ideal for pollution control applications in wood, grain, food, textile, paper, tobacco, rubber, and paint
industries, the Standard Series works beneath dust collectors and cyclone separators even with high temperatures and different pressure differentials.
