Flexicon Corporation (Australia) introduces a new line of single-trip bulk bag unloaders with a flexible screw conveyor designed for rapid discharging and conveying of material.
Flexicon’s single-trip bulk bag unloaders facilitate rapid, low-cost discharging in low headroom areas and conveying of the material at any angle to downstream processing, storage or packaging equipment.
Using a forklift or plant hoist to lower single-use bulk bags onto a four-bladed bag piercing knife that cuts the bag bottom from seam-to-seam, the single-trip bulk bag dischargers enable complete discharge from the bags without the use of flow promotion devices that would otherwise be needed to move material through narrow bag spouts.
Single-trip bag unloaders rely on the bag bottom to self-seal against a thick gasket affixed to the rim of the hopper and to discharge through a wide diameter hole in the centre of the gasket, eliminating the cost and additional headroom required for bag spout interfaces used on conventional unloaders of reusable bags.
An optional dust plenum, consisting of a hollow hopper rim with interior slots and exterior port vented to a plant dust collection system is offered as a secondary dust containment measure.
Using single-use bags, Flexicon’s single-trip unloaders offer faster discharge with less labour than possible with reusable bags. Additionally, since most reusable bags are discarded after one use, single-use bags can be less costly to purchase.
Equipped with a hinged door to access the interior safely, the hopper charges the intake adapter of an integral flexible screw conveyor that handles free- and non-free-flowing bulk materials ranging from large pellets to sub-micron powders.
These include products that pack, cake, seize, smear, fluidise, break apart or separate with no separation of blended products.
The hopper is also available with intake adapters and rotary airlocks for pneumatic conveying systems as well as with universal flanged outlets for connection to the user's downstream equipment.
The stainless steel construction is finished to industrial, food, dairy or pharmaceutical standards. Alternatively, the system is available in carbon steel with durable industrial finish.
Flexicon also manufactures bulk bag unloaders for reusable bags, bulk bag conditioners, bulk bag fillers, drum/box/container fillers and tippers, pneumatic conveying systems, bag dump stations, weigh batching and blending systems as well as engineered plant-wide bulk handling systems with automated controls.
