Bulk Bag Filling for Heavy Duty Applications
A new Flexicon® Bulk Bag Filling System for ultra-heavy-duty applications fills bulk bags with aggregates, abrasive minerals, powdered metals, dry chemical additives, filter press cake, and other bulk materials. The heavy-duty, skid-mounted system features a patented Twin-Centerpost™ frame that maximizes strength and improves accessibility to bag hooks while simplifying construction and reducing cost. A flexible screw conveyor with steel outer tube and high-capacity hopper feeds the filler consistently with a broad range of free- and non-free-flow bulk materials. The filler is mounted on load cells that transmit weight-gain signals to a controller that runs the conveyor at full feed rate and then at dribble feed rate immediately prior to stopping the conveyor once the target bag weight has been gained. It comes standard with forklift fill head height adjustment to accommodate all popular bag sizes and a feed chute outlet port for dust-free air displacement during filling. Automated functions include an inflatable collar to seal the bag inlet spout, an inflator to remove creases from the bag prior to filling, an automated vibratory densification/deaeration system to stabilize the bag and pneumatically retractable bag hooks that disconnect the bag from the filler, ready for removal by forklift.
