Gimat offers a wide range of standard and custom bulk bag unloading equipment, with innovative accessories for the constant improvement of performances, safety and cleanliness.
How it works
The big bag containing the raw materials arrives from the support structure by means of a forklift and is ready to be easily hung.
The telescopic design of the bulk bag unloaders makes it possible to adjust the height and rapidly adapt to the dimensions of the bulk bag with the assistance of a forklift or pneumatic pistons (optional).
Pneumatic lifting is optimal when the type of bulk bags to be hung changes frequently and/or the nature of the raw materials contained inside requires a few “height adjustments” to avoid the lateral swelling of the low part of the bulk bag. The latter function can be made automatic.
The hopper of the bulk bag discharger is equipped with an electro-mechanical vibrator helping the total emptying of the bulk bag content.
The upper rubber seal grants dust-free discharging operations.
The hopper underneath of the bulk bag emptying station, which pours the product, is fitted for coupling with the flexible spiral conveyors, screw conveyors or pneumatic conveyors.
If it is large enough, it can also be used as a temporary reserve to allow replacement of the empty bulk bag with a full one, without interrupting the feeding flow from below.

In case of noxious products or fine powders, the gasket mounted above the hopper seals the lower part of the bulk bag, making the unloading process airtight.
Moreover, upon request, the hopper hatch can be equipped with rubber gloves in order to open the bulk bag hatch without touching its content.
A slight vacuum is created inside the hopper to intake the more volatile particles by using the appropriate manifold to connect to the customer’s air suction system.
