How the Airlocks Rotary Valve Star Feeder Valve is Used?
When performing transfer on all pneumatic conveying lines, it is a device to
feed the material down to the line and separate the raw material
pneumatically transferred from the air. Blade forms, tolerances,
revolution speeds vary depending on type of process and type of the
product to be transported. Likewise, it may also act as breaker
depending on the characteristics of the material to be transported.
Even it may also operate coupled with the breakers.
Rotary Valve - Airlocks - Star Feeder may be made of ST37 Carbon Steel and AISI-304 AISI-316
Stainless Steel. Bedding types of the air locks may be mechanical
sealing and felt, again depending on the hot process.
Rotary Valve - Ailocks-Star Feeder internal Rotors have options such as blade, rounded type, adjusted
blade type, stripper and polyamide.
Rotary Valve -
Airlocks – Star Feeder That the Cell Wheel has that many options is completely
related with type of material to be transported as well as process.
This is so vital that a single fault may give damage to the material
to be transported. Simple solution commercially available may
deliver successful results for transfer of many materials such as
flour, cement and many more. However, a slight change in the granule
size and a different material means fail of such equipment.



Function of the valve-- is it airlock only, feeder
only, or airlock rotary valve -feeder? (Airlocks-rotary valve
only minimizes system air loss while allowing the transfer of
material between vessels with differing pressure; Feeder only
regulates the continuous flow of material between vessels sharing
the same pressure; Airlock-rotary valve-Feeder minimizes system air
loss while regulating the flow of material between vessels with
differing pressure)
What is feeding the rotary valve? (hopper, cyclone, shredder, silo,
filter receiver, dryer, baghouse, screw, mixer, other)
What is the rotary valve discharging into? (hopper, belt, tank,
screw, chute, vac line, airslide, mixer, pressure line, other)
Specific pressure measurement above and below the airlock. (positive,
negative, atmospheric)
Temperature above and below the airlock-rotary valve
A rotary valve is of no use by itself. Rotary valve, airlocks, and rotary valve are useful as one component in a bulk or specialty material handling system. Rotary Valve, Airlocks Feeders have wide application in industry wherever dry free-flowing powders, granules, crystals, or pellets are used. Typical materials include: cement, sugar, minerals, grains, plastics, dust, fly ash, flour, gypsum, lime, coffee, cereals, pharmaceuticals, etc...
While pneumatic transport processes differ according to the phases, it may also diffrent in the same phase. Low pressure, that is dilute phase transfer, can be categorized under 2 classes, namely vacuum and pressure. This classification shows, even slightly, differences in the rotary valve - airlocks. Consequently, we perform manufactures according to the air locks to be used on the vacuum and pressure line.
