Resin Particle Big Bag Discharger Bulk Bag Unloading Stations

Bulk bag unloader uses electric hoist to lift the bulk bag to the feed inlet and press the bag, then open the ton bag unloading mouth, and assisted by flapping device or vibration device to promote the material to fall into the below hopper.It can be connected to various equipment such as silo, screw conveyor, vacuum feeder, crusher and other equipment to form an automated production line.

This unloading system is also called bulk bag unloader, which is specially designed to provide a simple, clean and economical way to unload the entire contents of bulk bags and semi-bulk bags. It is suitable for almost any unloading or weighing application that uses bulk bags. Can be unloaded from bulk bags, jumbo bags, super bags or FIBC. The actual unpacking speed can be 5-8 times higher than the manual unpacking speed

The working principle of big bag unloader
-Lift the big bag to the equipment inlet by forklift or electric hoist;
-Manually or automatically open the discharge port of the ton bag;
-Open the flow valve and assisted by the vibration device to push the powder or granular materials (in the ton bag) by gravity into the hopper to complete the unpacking and unloading work.

Technical advantages: 
1. Dust free unloading: Specially designed bag clamping system of the unloading drum can completely prevent dust. 
2. I-beam electric hoist: Cantilevered I-beam with electric hoist and trolley allows positioning of bulk bag without the use of a forklift. 
3. Customized frame: Support frame is customized according to the working position and offered in carbon steel or stainless steel. 
4. Bag strap holder: Specially designed for fast, easy and secure insertion and removal of bag straps. Agitator paddles mitigate bridging and rat holes. 
5. Pneumatic agitator paddles: Ideal for use with material that is easily compacted or difficult-to-dispense. 
6. Hoppers: Hoppers in a wide variety of designs connect to processing equipment, pneumatic or screw conveyor.
