Why Choose Sanzhi Dust Special Compressor?
The main function of the specialized low-pressure air compressor for dust conveying is to efficiently transport dust, cement, and various other materials. This advanced system operates with a working pressure range of 0.15 to 0.4Mpa. It features a direct drive mechanism, a robust and large head operating at low rotational speeds, and a specialized oil-air separation structure engineered with cutting-edge German technology. This innovative design ensures minimal noise and vibration, eliminating the need for foundational installation. The air compressor provides a rapid flow rate with an oil content in the compressed air of less than 2PPM, ensuring the air volume meets the necessary specifications. Notably, the radiator lacks an after-cooling device, preventing moisture in the air stream, which is crucial for materials like cement and flour to avoid coking and caking, thus maintaining efficient transportation.
Sanzhi's special low-pressure air compressor for dust conveying boasts a broad spectrum of applications, including cement, mineral powder, coal ash unloading, and textile fermentation. It is designed for high efficiency and energy conservation. For instance, unloading a 9.6-meter cement tanker using the tanker's own device typically requires at least one and a half hours and consumes substantial fuel. In contrast, using a 37KW air compressor from Sanzhi reduces the unloading time to just 40 minutes. This significant improvement in efficiency not only saves time and energy but also reduces operational costs.
