Introducing our state-of-the-art Special Screw Air Compressor for Powder Conveying, crafted to revolutionize your industrial operations. This premium, closed-type, low-pressure, stationary screw air compressor is meticulously designed to cater to the rigorous demands of cement mixing plants, flour mills, coal ash processing, and mineral powder applications. With an impressive power range from 11KW to a robust 132KW, including versatile options such as 22KW, 37KW, 45KW, 55KW, 75KW, 90KW, and 110KW, this compressor promises unparalleled performance, exceptional efficiency, and unwavering reliability to elevate your operational excellence to new heights.
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 exceptional compressor operates using a direct drive mechanism, featuring a robust head and low rotational speed. Leveraging advanced German technology, it incorporates a unique oil-air separation structure that ensures minimal noise and vibration, thereby eliminating the need for foundational installation. The high-velocity compressed air contains less than 2PPM of oil, guaranteeing superior air volume and quality. Moreover, the radiator functions efficiently without an after-cooling device, which is crucial for materials like cement and flour that 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. This compressor's high efficiency and energy-saving design revolutionize operational processes. For example, 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.
