Bagger to handle dry, free-flowing products, typically larger size materials or blends, such as concrete, sand, etc., not extremely fine powders.  Bagger to be installed under product supply bin.  The RF-6 bagger comes standard all pneumatic and is a pneumatic conveying fluidizing bagger.  The pressure flow / assist principal of the RF-6 bagger uses the air pressure from the remotely located low pressure, high volume blower to provide the required / desired head pressure on the fluidization hopper.  Using high pressure (80 PSI) compressed air for fluidization, the RF-6 bagger does require a low pressure blower.

​

The upper product chamber of the bagger uses a semi-sealing funnel feed valve arrangement.  When the chamber becomes pressurized by the low pressure/high volume positive blower, the flapper / bladder valve seals, utilizing the material in the above supply bin to create a "backing" for the valve to close against.  The RF-6's funnel feed valve eliminates costly wear and time involved with repairing a butterfly valve which wears out quickly when bagging more abrasive, granular blends with large mesh aggregates.  The valve itself is inexpensive and easy to replace through the front access door of the funnel feed chamber.  The pressurization of the chamber means faster filling, tighter packed bags, and better bag weight accuracy.  The blower and pressurized chamber allows the customer to adjust between desired speed and accuracy.

The RA-14 bagger will fill and weigh a 50lb bag in as fast as 4 seconds.  The baggers actual fill speed is determined by several product related factors including incoming product head level, bulk density,

"free - flowability" and particle size.  Note, that it will become more difficult to retain accuracy when filling extremely fast.

​

Modular in design, multiple RF-6 baggers may be positioned side by side and equipped to automatically discharge the filled bag, typically onto a filled bag take-away conveyor, with all baggers simultaneously operating by one person.
