Introducing our Special Screw Air Compressor for Powder Conveying - the ultimate solution for your industrial needs. This state-of-the-art, closed-type, low-pressure, stationary screw air compressor is engineered to meet the demanding requirements of cement mixing plants, flour mills, coal ash processing, and mineral powder applications. Available in a range of power options from 11KW to a robust 132KW, including 22KW, 37KW, 45KW, 55KW, 75KW, 90KW, and 110KW, this versatile compressor ensures unparalleled performance, efficiency, and reliability for your operational excellence.
Why Choose the Sanzhi Dust Special Compressor?
The special low-pressure air compressor for dust conveying is meticulously engineered to handle materials such as dust, cement, and more. With a working pressure range of 0.15-0.4Mpa, this compressor utilizes a direct drive mechanism, featuring a large head and low rotational speed. Thanks to advanced German technology, it boasts a unique oil-air separation structure that ensures low noise and vibration, eliminating the need for foundational installation. The high-velocity compressed air contains less than 2PPM of oil, guaranteeing optimal air volume and quality. Additionally, the radiator operates without an after-cooling device, crucial for materials like cement and flour, which must remain moisture-free to prevent caking and ensure smooth conveying.
Sanzhi's specialized low-pressure air compressor for dust conveying offers unparalleled versatility, applicable in various industries including cement, mineral powder, coal ash unloading, and textile fermentation. Its high efficiency and energy-saving design revolutionize operational processes. For instance, while a 9.6-meter cement tanker's built-in unloading device takes at least an hour and a half and consumes substantial fuel, a 37KW air compressor accomplishes the same task in just 40 minutes. This remarkable efficiency translates into significant energy savings and cost reductions, making it an indispensable tool for modern industrial operations.

Safe and Zero Leakage Connection
Sanzhi's innovative use of high-rigid pipes and flexible joints replaces traditional hydraulic hoses, preventing bursts and ensuring flexible seals with rubber-type O-rings for zero leakage.
Aluminum Intake Valve
This valve, with its electricity-dependent loading and unloading functionality, includes noise elimination features, offering stable, durable, and wear-resistant performance.
Oil Viewing Mirror
Crafted from *** material, it provides excellent transparency and high-temperature resistance, enabling clear observation of oil levels and ensuring timely maintenance.
Excellent Air Filter
This superior air filter guarantees a clean air system with three-stage filtration, removing steam and dust to meet standard emissions and ensuring optimal air purification.
Oil Filter
Efficiently filtering impurities from the lubricating oil, this filter enhances lubrication for the head and prolongs the air compressor's lifespan.
High-Quality Soundproof Cotton
Enclosed in a compact noise reduction housing, the high-quality soundproof cotton significantly minimizes noise, ensuring vibration-free operation.
