A complete lower frame is available for applications where customers have an existing Crane Hoist Monorail System.[/spoiler] [spoiler intro=”Bulk Bag Hangers »”]

The bulk bag is attached to a bag hanger for raising and positioning the bag into the Bulk Bag Emptying support frame. All bag hangers allow easy attachment of the bag loops while securely holding Bag Emptying System.

Bag hangers can add options to retain bulk bag liners and prevent bag liners from extruding through the discharge spout into the downstream process equipment during bulk bag emptying.

Forklift Bag Hanger (Standard)

The standard fork lift-bag hanger includes all necessary guides to allow easy loading of the bag into the framework. Bulk Bag support hooks can be manually adjusted for various bag sizes.

Forklift Bag Hanger, Loop Retractor (Optional)

The Bulk Bag Emptying System can be fitted with an automatic loop retractor system for the Forklift Bag Hanger. The Forklift Bag Hanger Loop Retractor forms the bag into a conical shape aiding in a complete material discharge. The automatic operation draws the corners of the bag upward and inward as the product is discharged.

Dedicated Hoist Bag Hanger (Standard)

The standard hoist bag hanger has a Crossbrace Frame with overlapping bag loop retainers to safely hold the bag loops regardless of the loop strap tension.

Dedicated Hoist Bag Hanger, Loop Retractor (Optional)

The Bulk Bag Emptying System can be fitted with an automatic loop retractor system for the Dedicated Hoist Bag Hanger. The Hoist Bag Hanger Loop Retractor forms the bag into a conical shape aiding in a complete material discharge. The automatic operation draws the corners of the bag upward and inward as the product is discharged.

Inflatable Bladder Seal

The inflatable bladder seal provides dust control when used with lined bags. The operator places the spout of the bag inside the untie box pulling the outer liner over the bladder seal. The bladder seal is inflated against the spout forming a dust tight seal.

Bulk Bag Support Pan

The sloped support pan safely holds the bulk bag in the discharge position within the bag framework. Bulk Bag Piercing Hopper Bulk Bag Piercing Hopper has a removable triangular blade assembly, which pierces the center of unspouted bags allowing the material to discharge. The bottom of the bulk bag is fitted with a large diaphram, to reduce dust during the discharge process. The blade ruptures the membrane of the bags diaphragm causing the product to be discharged.[/spoiler] [spoiler intro=”Conveying & Processing Interfaces »”]

A wide variety of options are available to integrate bulk bag unloaders with material conveying systems and downstream process equipment. The material flow characteristics and the specifics of the customer’s bulk bag emptying application dictate the type of bulk bag discharger interface utilised.

Surge Hopper

Surge Hoppers with various capacity, can be utilised to provide continuous material supply while removing empty bags and loading full bags into the Bulk Bag Emptier. The inlet to the surge hoppers are typically connected to a bag spout interface option while the discharge is often connected to a conveying system.

Agitator Hopper

This U-shaped hopper has a mechanical agitator which eliminates the potential

of material bridging or forming a rat hole above the inlet to material conveying

equipment. The design of the agitatior draws the material away from the sides,

directing it through the center discharge on a consistent and reliable basis.

Combination Hopper

The combination hopper allows emptying of small bags, sacks, drums, and other containers in addition to bulk bags. Combination hoppers can be fitted integral dust collectors or tube stubs for connection to centralized dust collection systems.

Size Reduction Equipment

Rotating shaft(s) with staggered breaker bars deagglomerates materials as they pass through stators to reduce materials to a conveyable particle size.

Feeder Systems

Volumetric and loss-in-weight feeders are utilised to control the transfer of materials directly from the bulk bag discharger to conveying or downstream process equipment.[/spoiler] [spoiler intro=”Associated Equipment »”]
