Introducing the exceptional Special Screw Air Compressor from Sanzhi (Henan) Compressor Co., Ltd., masterfully engineered for optimal Powder Conveying. This Closed Type Low Pressure Stationary Screw Air Compressor stands as the ideal choice for a multitude of industrial applications, including Cement Mixing Plants, Flour Mills, Coal Ash management, and Mineral Powder processing. With a versatile range of power options - 11KW, 22KW, 37KW, 45KW, and 55KW - this powerhouse guarantees unrivaled performance and steadfast reliability, making it the perfect solution for your industrial needs.
Why Choose the Sanzhi Dust Special Compressor?
Our Special Low Pressure Air Compressor for Dust Conveying is meticulously engineered to handle dust, cement, and other particulates with exceptional efficiency. Operating within a pressure range of 0.15-0.4Mpa, it boasts a direct drive mechanism, a robust large head, and a low rotational speed. Infused with advanced German technology, its unique oil-air separation structure guarantees low noise and minimal vibration. Designed with user convenience in mind, it requires no foundation for installation. The high-speed flow of compressed air, containing less than 2PPM of oil, ensures an optimal air volume. Additionally, the radiator is crafted without an after-cooling device, expertly preventing moisture-related issues in materials such as cement and flour, thereby avoiding coking and caking for uninterrupted conveying.
Sanzhi's special low-pressure air compressor for dust conveying is a paragon of versatility and efficiency, perfectly suited for a range of applications including cement, mineral powder, coal ash unloading, and textile fermentation. This powerhouse not only saves energy but also significantly boosts productivity. For example, unloading a 9.6-meter cement tanker with traditional equipment consumes in excess of 1.5 hours and substantial fuel. In stark contrast, our 37KW air compressor completes the same task in a remarkable 40 minutes, delivering unmatched efficiency and considerable cost savings.
Direct-Connected Rotation Motor
Featuring an insulation grade of F and a protective grade of IP55, this motor offers an unwavering flow rate, consistent load handling, remarkable efficiency, and exceptional durability, ensuring seamless and steadfast operations.
German Technology Air End
Our air end utilizes a large rotor and low-speed design, delivering high efficiency, reduced noise, minimal vibrations, and unparalleled reliability. It promises decreased leakage and superior volumetric efficiency.
Smart Button Screen
The intuitive smart button screen features clear, concise functions, easy operation, swift response times, and vibrant display colors, simplifying maintenance.
Cooling System
Engineered with an expansive heat exchange area, our cooling system adeptly prevents high temperatures, curtailing oil emulsification and coking to sustain peak machine performance.
Reliable Oil and Air Separator
Our vertical tangential cyclone separation structure ensures thorough oil and air separation, facilitating straightforward cartridge replacement and reducing maintenance expenditures.
Safe and Zero Leakage Connection
Departing from traditional low-cost hydraulic hoses, Sanzhi uses high-rigid pipes and flexible joint connections to avert bursts and ensure a flexible seal with rubber-type O-rings, guaranteeing zero leakage.
Aluminum Intake Valve
Operated by an electric load, our aluminum intake valve offers unloading and air replenishing capabilities while minimizing noise. It ensures stable, durable performance with a smooth, wear-resistant surface.
Oil Viewing Mirror
Crafted from premium PMMA material, our oil viewing mirror provides excellent transparency, high-temperature resistance, and minimal color change. It allows for visual monitoring of oil levels and lubrication, ensuring timely replacements to prevent equipment damage.
Excellent Air Filter
Our air filter ensures superior air purification, maintaining a pristine air system through a three-stage filtration process. It effectively removes steam and tiny dust particles, meeting standard emissions and ensuring optimal air quality.
