Introducing our premium and innovative Special Screw Air Compressor, meticulously crafted to revolutionize powder conveying applications. This state-of-the-art compressor, engineered as a closed-type, low-pressure, stationary screw air compressor, is the ultimate solution for a diverse array of sectors. From cement mixing plants and flour mills to coal ash handling and mineral powder processing, our compressor stands as a beacon of efficiency and power. Available in a comprehensive range of power options-11KW, 22KW, 37KW, 45KW, and 55KW-this versatile compressor guarantees unparalleled performance and reliability. It is specifically designed to meet and exceed the rigorous demands of your industrial operations, ensuring seamless and efficient process integration.
Why choose Sanzhi dust special compressor?
The primary function of the specialized low-pressure air compressor, meticulously crafted for dust conveying, is to adeptly transport dust, cement, and similar materials with unparalleled efficiency. Operating within a versatile pressure range of 0.15-0.4Mpa, this state-of-the-art machine boasts a direct drive system, featuring an impressive large head and maintaining a low rotational speed for optimal performance. Engineered with an ingenious oil-air separation structure, inspired by superior German technology, it ensures exceptionally low noise and minimal vibrations, completely eliminating the necessity for foundational installations. The compressor's swift and consistent airflow guarantees that the compressed air maintains an oil content of less than 2PPM, thus ensuring the precise required air volume. Furthermore, the radiator operates seamlessly without an after-cooling device, as it is essential to avoid moisture during the conveying process to prevent any form of caking and coking, which would otherwise impair performance. This meticulously thought-out design ensures optimal conveying efficacy, making it ideal for applications involving cement, or even delicate materials like flour.
Sanzhi presents a specialized low-pressure air compressor, expertly tailored for the demands of dust conveying, with versatile applications spanning cement, mineral powder, coal ash unloading, and textile fermentation. This high-efficiency marvel is an energy-saving solution that significantly amplifies productivity while slashing costs. For example, the arduous task of unloading a 9.6-meter cement tanker, typically taking a minimum of 1.5 hours and being fuel-intensive and inefficient, is effortlessly transformed. By utilizing a 37KW air compressor from Sanzhi, the time is dramatically reduced to a mere 40 minutes, significantly enhancing efficiency, conserving valuable energy, and cutting down operational costs.
