Product Description

Introducing our Special Screw Air Compressor, expertly designed for Powder Conveying. This Closed Type Low Pressure Stationary Screw Air Compressor is perfect for Cement Mixing Plants, Flour Mills, Coal Ash, and Mineral Powder applications. Available in multiple power options - 11KW, 22KW, 37KW, 45KW, and 55KW - it promises unmatched performance and reliability.

Product Structure

 

Why Choose the Sanzhi Dust Special Compressor?

Our Special Low Pressure Air Compressor for Dust Conveying is meticulously engineered to handle dust, cement, and other particulates efficiently. With a working pressure range of 0.15-0.4Mpa, it features a direct drive mechanism, a robust large head, and low rotational speed. German technology enhances its special oil-air separation structure, ensuring low noise and low vibration. The installation requires no foundation, and the fast flow rate of compressed air with oil content under 2PPM guarantees optimal air volume. The radiator is designed without an after-cooling device to prevent moisture in materials like cement and flour, avoiding coking and caking for seamless conveying.

Sanzhi's special low-pressure air compressor for dust conveying is versatile and highly efficient, catering to various applications such as cement, mineral powder, coal ash unloading, and textile fermentation. It saves energy and enhances productivity; for instance, unloading a 9.6-meter cement tanker with a conventional device takes over 1.5 hours and consumes significant fuel. In contrast, our 37KW air compressor completes the task in just 40 minutes, boosting efficiency and cost savings.
