This system transfers content of a bulk bag for packing into 10-100lb valve bags. It can be used to transfer bulk material that is in powder or small granular form. This includes material such as finish cement, bentonite, barite, fertilizers, frac sand, powdered limestone, gypsum, powdered iron ore, oil drilling chemical powders, titanium dioxide and more.
Bulk bags are loaded onto the bulk bag unloader using a fork truck or hoist. The bulk bag unloader uses a knife opening system to discharge material from the bulk bag into the surge hopper below.
Bulk material is then conveyed from the unloader, using a screw conveyor, to the surge hopper located above the valve bag filling machine. The screw conveyor is controlled by a level controller located in the surge hopper above the valve bag filling machine. A manual slide gate located on the screw conveyor also allows for temporary bypass of material into a hopper or a tote bin if valve bag filling is not required.
System controls include a controller for the valve bag filling machine and the screw conveyor. The system is prewired and pre-piped. Clients provides power and compressed air to control enclosure located on valve bag filling machine.
