Combined hammer blaster for powder handling
In bulk material handling, challenges such as bridging or rat-holing of powders in silos and bins are common, leading to interrupted material flow and operational inefficiencies. Powders with hygroscopic properties or those prone to packing under pressure are particularly problematic in these scenarios.

Combines mechanical impacts with high-pressure air blasts
The PJ Combined Hammer Blaster by WAMGROUP is designed to address material flow issues in bulk handling systems. It combines a mechanical hammer impact with a high-pressure air blast to prevent material bridging and rat-holing. The unit operates intermittently at pressures ranging from 3 to 6 bar (44 to 87 PSI), making it effective for dislodging even fine, dry powders that pack under pressure. The robust design, featuring a galvanized steel POM external body, allows for both indoor and outdoor installation. The system includes a mounting plate for secure attachment and a safety chain to prevent accidental dropping during installation or maintenance. Available in three sizes, the PJ Combined Hammer Blaster is ideal for industries dealing with difficult powders, such as building materials, chemicals, and other dry bulk materials.
