The big bag High Speed Twin is constructed to fill two lines of FIBC bags at the same time. The machine automatically weighs and fills bags of 100 to 1250 kg. This machine is suitable for powder and granular materials. The whole machine is standing on four support legs.
Two stainless steel weighing scales are mounted in the machine frame, the storage hopper also stands on these legs. The two scale hoppers are mounted on load cells which are located under the storage hopper. Under the storage hopper there are also mounted two pneumatic halve moon valves which fill the two scale hoppers. When dosing the product, a large or fine opening can be used. This operation is done automatically by pneumatic cylinders. The weighing scale hopper unloads into a stainless steel pipe that fits into the big bag. The scale system operates with an Avery Salter Weightronix weighing indicator. The machine weighs the material without weighing the bag.
The whole unit operates automatic and manual operation is also possible. The big bag High Speed Twin is located above two big bag conveyors that transport the bags away from the filling pipe. Before the filling process starts the big bag is held up and manually closed around the filling pipe. The filling pipe is adjustable in height over a length of 400 mm. that makes the filing of different bag sizes possible. Before the big bag will be filled, a blower will blow air into the bag until the big bag has its full size.
