Product Structure

Why choose Sanzhi dust special compressor?

Introducing Sanzhi's revolutionary low-pressure air compressor, an exceptional creation crafted specifically for dust conveying. This essential powerhouse is designed to transport dust, cement, and a diverse array of materials with unmatched efficiency. Operating flawlessly within a strategic pressure range of 0.15-0.4Mpa, it features an advanced direct drive mechanism, a generously proportioned head, and a low rotational speed to ensure peak performance. At the heart of its innovation is a unique oil-air separation structure, engineered to perfection with precision German craftsmanship. Enjoy the benefits of exceptionally low noise levels and minimal vibration, making it a quiet titan in any setting. The foundation-free installation further simplifies setup, making integration into your operations a breeze. Delivering a rapid flow rate of compressed air with an impressively low oil content of less than 2PPM, it superbly meets and exceeds volume requirements. With a radiator sporting an innovative design, the need for an after-cooling device is eliminated, making it exceptionally suited for moisture-sensitive materials like cement and flour. This ensures prevention of coking and caking, guaranteeing smooth and uninterrupted conveyance.

Sanzhi proudly introduces a specialized low-pressure air compressor, ingeniously tailored for dust conveying. Known for its versatile applications across numerous sectors, this remarkable compressor excels in areas such as cement, mineral powder, coal ash unloading, and textile fermentation. It stands as a beacon of efficiency and energy conservation, redefining industry standards. Consider the case of a typical 9.6-meter cement tanker, which would traditionally take over an hour and a half to unload with existing equipment, leading to high fuel consumption and inefficiency. Enter Sanzhi's formidable 37KW air compressor, which slashes unloading time to a mere 40 minutes. This dramatic enhancement in efficiency translates to significant reductions in fuel consumption and substantial cost savings, setting new benchmarks in operational excellence.
