The PNEUCON Jumbo Bag Unloading System, also known as Jumbo bag dischargers and super sack unloaders are specifically designed to provide an easy, clean and economical way to discharge the entire contents of bulk and semi-bulk bags, especially when the material is less than free-flowing.
Jumbo bags can be placed in the Jumbo bag unloader by fork lift, hoist or crane from floor level. An integral hoist on a monorail can be furnished if desired. Standard arrangement includes a bag frame to which the suspension loops of the bag can be attached while the bag is resting on the floor. The bag frame is then raised and positioned so the hooks on the frame engage a counter-balanced suspension frame in the superstructure of the unloaded. When lowered, the bottom of the bag rests on a sealing ring in the unloader bed and the tension on the bag loops keeps the bag upright. Optional pneumatically operated actuator petals massage the lower portion of the bag to promote material flow toward the center of the bag.
Material can discharge by gravity into storage, a process vessel or a conveying system for transfer to another location. Modular construction of the discharge portion underneath the bed facilitates the use of a wide range of devices such as feed screws, rotary valves, lump breakers.
