Discover the pinnacle of engineering with our Special Screw Air Compressor tailored specifically for Powder Conveying. This Closed Type, Low Pressure, Stationary Screw Air Compressor is the optimal choice for diverse industrial applications such as Cement Mixing Plants, Flour Mills, Coal Ash management, and Mineral Powder handling. Available in a range of power outputs including 11KW, 22KW, 37KW, 45KW, and 55KW, it ensures unparalleled efficiency and reliability for your operational needs.
Why choose Sanzhi dust special compressor?
The primary function of our specialized low-pressure air compressor for dust conveying is the efficient transportation of dust, cement, and similar materials. Operating at a working pressure range of 0.15-0.4Mpa, this compressor features a direct drive system, large head, and low rotational speed. Engineered with a unique German-designed oil-air separation structure, it ensures minimal noise, reduced vibration, and requires no foundation for installation. Enjoy the benefits of a rapid compressed air flow, with an impressively low oil content of less than 2PPM, guaranteeing optimal air volume to meet your needs. The radiator operates without an after-cooling device, crucial for conveying materials like cement and flour that must remain moisture-free to prevent caking and clogging, ensuring a smooth and efficient transportation process.
Sanzhi's special low-pressure air compressor for dust conveying is a versatile and energy-efficient solution with a wide array of applications, including cement, mineral powder, coal ash unloading, and textile fermentation. For instance, while a 9.6-meter cement tanker typically requires at least one and a half hours for unloading using its built-in device, consuming substantial fuel and proving inefficient, our 37KW air compressor accomplishes the task in just 40 minutes. This vastly enhances efficiency, conserves energy, and results in significant cost savings.
Direct-Connected Rotation Motor
Featuring insulation grade F and protective grade IP55, this motor ensures a stable flow rate. Its constant load capability, coupled with high efficiency and exceptional durability, makes it a reliable choice.
German Technology Air End
The air end is designed with a large rotor and low-speed operation, promising high efficiency and low noise. This advanced design minimizes vibration, enhances reliability, ensures less leakage, and boosts volume efficiency.
Smart Button Screen
The interface is intuitive with concise and clear functions. It offers simple operation, fast response, vibrant display colors, and easy maintenance.
Cooling System
Designed with a large heat exchange area, this system effectively prevents high-temperature issues and reduces oil emulsification and coking caused by excessive heat.
Reliable Oil and Air Separator
Utilizing a vertical tangential cyclone separation structure, it ensures complete separation of oil and air. The design allows for easy cartridge replacement and reduces maintenance costs.
Safe and Zero Leakage Connection
Sanzhi has innovated beyond traditional low-cost hydraulic hose designs. By utilizing high-rigid pipes and flexible joint connections, Sanzhi prevents bursts caused by aging and ensures a leak-free performance with a rubber type O-ring for a flexible seal.
Aluminum Intake Valve
This valve operates by loading with electricity and unloading without it, providing air replenishment and noise elimination for the host. It boasts stable, durable performance with a smooth, wear-resistant surface.
Oil Viewing Mirror
Crafted from *** material, this mirror offers excellent transparency, high temperature resistance, and minimal color change. It allows users to visually monitor oil levels and lubrication use, ensuring timely replacements and additions to prevent equipment damage.
Excellent Air Filter
With superior air purification capabilities, this filter ensures a clean air system through three-stage filtration. It maximizes air purification, meets emission standards, and effectively removes steam and fine dust.
Oil Filter
This filter removes impurities from the lubricating oil, thus enhancing lubrication of the head and extending the lifespan of the air compressor.
High-Quality Soundproof Cotton
A compact noise reduction housing works in tandem with high-quality soundproof cotton to minimize vibration amplitude during operation and significantly improve noise reduction levels.
