Product Structure

Why choose Sanzhi dust special compressor?

Introducing the groundbreaking Low-Pressure Screw Air Compressor from Sanzhi, a marvel of engineering meticulously crafted for dust conveying applications-an indispensable asset in the seamless transport of dust, cement, and various materials with unmatched efficiency. Operating effortlessly within a pressure range of 0.15-0.4Mpa, this machine features a sophisticated direct drive mechanism, a generously proportioned head, and a low rotational speed, all fine-tuned for peak performance. It boasts a unique oil-air separation structure, perfected with the precision of German engineering, ensuring exceptionally quiet operations with minimal vibration. Its foundation-free installation simplifies the setup process significantly. This compressor delivers a rapid flow rate of compressed air, maintaining an oil content of under 2PPM, impeccably aligning with volume requirements. The radiator's inventive design obviates the need for an after-cooling device, making it exquisitely suited for moisture-sensitive materials like cement and flour, thereby preventing coking and caking, and guaranteeing smooth, uninterrupted conveyance.

Sanzhi proudly introduces a specialized low-pressure air compressor, engineered meticulously for dust conveying, renowned for its wide-ranging applications in industries such as cement, mineral powder, coal ash unloading, and textile fermentation. This pioneering compressor epitomizes efficiency and energy conservation. Consider a standard 9.6-meter cement tanker, which typically requires over an hour and a half for unloading using conventional equipment, leading to high fuel consumption and inefficiency. In stark contrast, Sanzhi's potent 37KW air compressor slashes unloading time to merely 40 minutes, significantly boosting efficiency, drastically cutting fuel consumption, and delivering substantial cost savings.
