Hammer blaster for bridging and ratholing prevention
In industries dealing with bulk materials, preventing flow interruptions such as bridging and ratholing is critical. Powders that tend to pack or possess hygroscopic properties often cause significant operational challenges, leading to downtime and inefficiencies.

Effective material flow with combined hammer and air blast
The PJ Combined Hammer Blaster by WAMGROUP effectively addresses common bulk material flow issues by combining a mechanical hammer impact with a high-pressure air blast. This dual-action device is especially suitable for fine, dry powders that tend to pack under pressure. Its robust design allows for reliable operation in both indoor and outdoor environments, making it versatile across various installation settings. The system operates intermittently at pressures ranging from 3 to 6 bar (44 to 87 PSI), ensuring that bulk materials move smoothly and efficiently. Manufactured from galvanized steel POM for durability, the device includes a mounting plate and safety chain to prevent accidental dropping during installation or maintenance. The PJ Combined Hammer Blaster is available in three sizes to suit different application needs.
