YJD 18 Rotary Airlock Valve Stainless Steel Or Cast Iron Rotary
Airlock Feeder In Blue
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,
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
