Discover the epitome of excellence with our cutting-edge Special Screw Air Compressor, a masterpiece designed to redefine the landscape of powder conveying applications. This closed-type, low-pressure, stationary screw air compressor is the ideal choice for a variety of industries such as cement mixing plants, flour mills, coal ash management, and mineral powder processing. With unmatched versatility, our compressor is offered in a spectrum of power configurations including 11KW, 22KW, 37KW, 45KW, and 55KW, delivering extraordinary performance and unwavering reliability. This ensures that your industrial needs are not just met but surpassed.
Why choose Sanzhi dust special compressor?
The primary function of the specialized low-pressure air compressor designed for dust conveying is to efficiently transport dust, cement, and similar materials. Operating within a pressure range of 0.15-0.4Mpa, this cutting-edge machine employs a direct drive system, characterized by a large head and low rotational speed. Expertly crafted with an innovative oil-air separation structure inspired by leading German technology, it ensures quiet operation and minimal vibration, removing the necessity for foundational installation. The compressor's swift airflow guarantees compressed air with an oil content of less than 2PPM, thus meeting the required air volume specifications. Furthermore, the radiator operates seamlessly without an after-cooling device to prevent moisture buildup, which could lead to caking and coking, adversely affecting performance. This meticulously engineered design optimizes conveying efficiency for materials like cement and even flour, ensuring unparalleled operational excellence.
Sanzhi presents a specialized low-pressure air compressor perfectly engineered for dust conveying across various applications, including cement, mineral powder, coal ash unloading, and textile fermentation. This highly efficient, energy-saving innovation significantly amplifies productivity while driving substantial cost reductions. Consider, for instance, the task of unloading a 9.6-meter cement tanker, which typically takes no less than 1.5 hours and is both fuel-intensive and inefficient. However, by utilizing a 37KW air compressor from Sanzhi, this process is streamlined to just 40 minutes, remarkably boosting efficiency, conserving valuable energy, and slashing operational expenses.
