Section 4 – Operation
- ,* 6 , -)
CAMCORP fabricated rotary airlocks are designed to provide metered dry
granular, pelletized or powdered materials at a controlled rate from a bin, hopper,
screw conveyor or dust collector to a downstream destination such as a tank,
scale hopper, screener or drum. Fabricated rotary airlocks use a rubber wiper
attached to the rotor vanes to provide a seal. Some air will be reintroduced into
the attached equipment as empty rotor pockets return to the material inlet.
Discharge rates can be increased or decreased by changing the RPM of the
airlock rotor. This can be achieved by changing the sprocket ratio of the drive or
by using a variable frequency drive. Caution should be taken to assure that the
motor supplied is inverter duty in the application of a variable frequency drive.
