Combined hammer blaster for powder handling
Address powder flow issues with ease by preventing bridging and ratholing, ensuring seamless material discharge through innovative combined hammer and high-pressure air technology. Ideal for maintaining efficient production in environments dealing with dry and hygroscopic powders.

Facilitates Bulk Material Flow with Vibration and Air Blasts
The PJ Combined Hammer Blasters from WAMGROUP are engineered to optimize bulk material handling processes by tackling common flow issues such as bridging and rat-holing. This versatile equipment combines mechanical vibration with high-pressure air blasts to maintain consistent material movement, particularly effective with dry, fine, or hygroscopic powders. Ideal for industries handling building materials, chemical ad-mixtures, and pharmaceutical powders, it ensures operational efficiency in pre-processing, processing, and final conditioning steps. Operating intermittently at pressures between 3 to 6 bar, these blasters integrate seamlessly into existing systems with pneumatic operation, and are supplied with mounting plates for easy installation on silos or bins. Available in three sizes, the blasters feature a patented compact design with integrated valves and are constructed from robust galvanized steel, offering durability for both indoor and outdoor applications.
