Hammer blaster for bridging and ratholing prevention
Eliminate material blockages with a dual-action system designed to prevent ratholing and bridging in bulk powders, ensuring consistent flow and reducing downtime in your process line.

Combats Powder Bridging and Enhances Material Flow
The PICJET PJ Combined Hammer Blasters from WAMGROUP offer a dual-action solution for enhancing material flow by addressing common issues like powder bridging and rat-holing. Utilizing both mechanical impact and a high-pressure air blast, the PICJET PJ ensures effective material flow in challenging environments across industries such as building materials, chemical admixtures, and tobacco processing. This equipment is essential in handling powders and admixtures, particularly in bulk storage and silo applications. It operates intermittently under pressure ranging from 3 to 6 bar, providing flexibility for various operations. Designed for both indoor and outdoor installations, the robust galvanized steel and POM construction offers durability. With multiple sizes available and a safety chain for installation, the PICJET PJ is easily adaptable and integrates seamlessly into existing systems. Additionally, it is compatible with different voltage coils and includes a timer for adjusting blast periods, ensuring precise material handling and flow management.
