1.1. APPLICATION
Meyer Rotary Airlock/Feeders are used in pneumatic conveying systems,
dust control equipment and as volumetric feeders to maintain an even flow
of material through processing systems.
The basic use of the Roto-Flo is as an airlock transition point, sealing
pressurized systems against loss of air or gas while maintaining a flow of
material between components with different pressure. Roto-Fio units are
also widely used as volumetric feeders for metering materials at precise
flow rates from bins, hoppers or silos into conveying or processing
systems.
Roto-Flo Rotary Airlock/Feeders have wide application in industry
wherever dry free-flowing powders, granules, crystals or pellets are used.
Typical materials handled with Roto-Flo units include: cement, sugar,
minerals, grains, plastics, dust, fly ash, flour, gypsum, lime, coffee and
cereals etc
