Dust lock and rotary feeder
Rotary dust locks and rotary feeders are used for volumetric dosing of loose materials occurring in the form of various types of powders, powders, poppies, middlings, grains or pellets from spaces where there may be a difference in air pressure.
The locks have cells that regularly open and close during operation. Such a gate is often called cellular.
SC rotary lock gates are used primarily for emptying accumulated material from cyclones, unloading silos and tanks, collecting material from shredders, sieves as well as in the pneumatic transport system.
SCV rotary vane locks are mainly used for dosing loose materials to TESTMER CV coolers, as well as to other devices in pneumatic and gravity transport.
An optional shaft rotation sensor is possible.
