The ton bag feeding station, also known as the jumbo bag unloading station, is an automatic unloading device designed for powder and granular materials. It is widely used in chemical, grain, mining, building materials and other industries, realizing dust-free and efficient unpacking and feeding of materials packed in ton bags.
Centered on gravity unloading, its working principle relies on the coordination of auxiliary arch-breaking, sealed dust removal and clamping & locking structures. During operation, a full ton bag is hoisted above the feeding inlet by lifting equipment such as cranes and electric hoists, positioned accurately and then lowered slowly. After the bottom of the ton bag fits closely with the equipment flange, the clamping device is activated to tightly seal and lock the bag mouth, preventing dust leakage during discharging.
Next, open the discharge opening of the ton bag. Materials slide down by gravity and enter the silo, conveyor, reactor and other downstream equipment. For materials with poor fluidity and easy caking, the equipment is equipped with vibrators and arch-breaking devices to loosen materials through high-frequency vibration, avoiding bridging and blockage and ensuring smooth discharging. The whole unloading process is carried out in a closed environment. The supporting dust removal system collects floating dust in a timely manner and discharges clean air after filtration to achieve dust-free operation.
After complete material emptying, close the discharge opening, release the clamping mechanism, and lift away the empty ton bag to finish one feeding cycle. Featuring a compact structure and simple operation, this equipment effectively reduces manual labor intensity in unpacking, eliminates dust pollution, and ensures continuous and stable material conveying. It is an indispensable front-end unloading device for automated powder production lines.
