Design Background
Currently there are few, if any “Effective” Bridge Breakers/Silo Dischargers in the modern market. Most devices solve one problem but create another, e.g., Knocking/vibration might sometimes solved powder bridging but do damages the silo and often segregate the powders. Air injection requires high amount of dry compressed air and bears the risk of dust explosion in the silo, etc., thus making problem-free days a rarity.
Sirius’s Bridge Breaker/Silo Discharger can do the job for you, it has unique features designed specifically to solve powder bridging problem from all kinds of materials.
