Key Applications of High Pressure Blowers in Construction & Mining
1. Dust Collection Systems
High pressure blowers providing suction for dust collection from crushers, screens, conveyors, and drilling rigs. Pressure range: 400-800 mmWC. Required for bag filter and cyclone system operation.
2. Pneumatic Conveying of Minerals
High pressure air for dense phase or dilute phase conveying of minerals (iron ore fines, coal powder, limestone dust, aggregates). Pressure range: 500-1,500 mmWC.
3. Mine Dewatering (Air Lift Pumping)
High pressure blowers for air lift pumping systems to remove water from mine sumps and open pit mines. Pressure range: 800-2,000+ mmWC depending on lift height (up to 50-100 meters).
4. Tunnel Ventilation
High pressure fans for long duct runs in tunnel boring machine (TBM) ventilation and underground construction. Pressure range: 500-1,200 mmWC for ducted systems up to 2-3 km.
5. Bag Filter Reverse Pulse Cleaning
High pressure compressed air for cleaning filter bags in dust collection systems at crushers and screens. Pressure range: 600-1,000 mmWC.
6. Material Handling (Air Slides / Fluidization)
High pressure air for fluidizing materials in hoppers and silos, and for air slide conveyors. Pressure range: 400-800 mmWC.
Working Principle – High Pressure Centrifugal Blower
High pressure centrifugal blowers (also known as high pressure fans) use a high-speed impeller with backward-curved or radial tip blades to generate significant static pressure. Air enters axially through the inlet, is accelerated radially by the impeller, and is then discharged through a scroll housing. The high rotational speed and precision impeller design enable pressure generation up to 2,000+ mmWC, making them ideal for dust collection, pneumatic conveying, and mine dewatering applications.

Mine Dewatering – Air Lift Pumping Application
Shivam Engineering & Fabrication specializes in high pressure blowers for mine dewatering using the air lift pumping principle:
- How it works: High pressure air is injected at the bottom of a lift pipe. The air-water mixture becomes lighter than the surrounding water, creating lift.
- Advantages: No moving parts in the mine sump, handles dirty/muddy water, low maintenance, can lift from deep sumps (50-100+ meters).
- Pressure Requirement: For every 10 meters of lift height, approximately 150-200 mmWC pressure is required. For 50 meters lift: 800-1,000 mmWC. For 100 meters lift: 1,500-2,000+ mmWC.
- Typical Applications: Open pit mine dewatering, underground mine sump pumping, construction site dewatering, quarry water removal.
