This bulk bag unloader system unloads and transfers fine powder from a big bag and conveys it to a valve bagging machine for packaging.
First, a bulk bag containing powder is placed in the surge hopper. An operator unties the bag allowing material to dispense into the surge hopper. Next, a screw conveyor conveys the powder to a surge hopper located above the valve bagging machine located in an adjacent room. There is a level control in the surge hopper located above valve bagging machine that controls the operation of the screw conveyor. The valve bags are filled and densified. Then they are conveyed through a bag flattener conveyor and then to a palletizing machine.
This system also includes a free standing reverse pulse bag type dust collector with blower designed to collect dust from the bulk bag unloading hopper and the valve bagging machine. Dust from the dust collector is discharged into a 55 gallon drum. All controls come pre-wired and pre-piped ready for quick installation.
