Product Structure

Why choose Sanzhi dust special compressor?

Introducing the revolutionary low-pressure air compressor by Sanzhi, meticulously crafted for dust conveying-a quintessential powerhouse for expertly transporting dust, cement, and a variety of materials with unmatched efficiency. Operating effortlessly within a reliable pressure range of 0.15-0.4Mpa, this state-of-the-art machine integrates a direct drive mechanism, a significantly sized head, and a low rotational speed to guarantee unparalleled performance. Featuring a unique oil-air separation structure, engineered with exquisite German precision, this compressor ensures exceptionally low noise levels and minimal vibration. Its foundation-free installation allows for an astonishingly straightforward setup, making the process as seamless as possible. Remarkably, the compressor delivers a rapid flow rate of compressed air with an oil content of less than 2PPM, perfectly satisfying volume requirements. The radiator's innovative design eliminates the necessity of an after-cooling device, rendering it ideal for moisture-sensitive materials like cement and flour, thus preventing coking and caking, and ensuring smooth and uninterrupted conveyance.

Sanzhi proudly unveils a specialized low-pressure air compressor, masterfully tailored for dust conveying, renowned for its versatile applications across industries such as cement, mineral powder, coal ash unloading, and textile fermentation. This groundbreaking compressor stands as a paradigm of efficiency and energy conservation. Consider a typical 9.6-meter cement tanker, which traditionally requires over an hour and a half to unload using its own equipment, resulting in high fuel consumption and inefficiency. With Sanzhi's formidable 37KW air compressor, unloading time is dramatically reduced to just 40 minutes, significantly boosting efficiency, slashing fuel consumption, and delivering substantial cost savings.
