Product Description
Special Screw Air Compressor for Powder Conveying, Closed Type Low Pressure Stationary Type Screw Air Compressors for Cement Mixing Plant, Flour mill, Coal Ash, Mineral Powder, 11KW, 22KW, 37KW,45KW, 55KW, 75kw, 90KW, 110KW,132KW
Why choose Sanzhi dust special compressor?
The main function of the special low pressure air compressor for dust conveying is to convey dust and cement and some other things, the working pressure is 0.15-0.4Mpa, adopts direct drive, large head, low rotational speed, special oil-air separation structure designed by German technology, low noise, low vibration, no need for any foundation for installation, the fast flow rate of compressed air, compressed air oil content is less than 2PPM, to ensure that the air volume to meet the required requirements. Radiator without after-cooling device, because in the process of conveying, not only cement, including flour, can not have moisture, otherwise it will be coking and caking, seriously affecting the conveying effect.
Sanzhi produces a special low-pressure air compressor for dust conveying, which has a wide range of applications, such as cement, mineral powder, coal ash unloading, textile fermentation, etc. It is highly efficient and energy-saving. For example, it takes at least one and a half hours to unload a 9.6-meter cement tanker by the tanker's own unloading device, which consumes a lot of fuel and is inefficient, but it takes only 40 minutes to unload a 37KW air compressor, which greatly improves the efficiency, saves energy and saves money.
Direct-Connected Rotation Motor
Insulation grade F, protective grade IP55, stable flow rate. Constant load, high efficiency and durability.
German Technology Air End
The air end adopts a large rotor, a low-speed design, high efficiency, low noise, low vibration, high reliability, with less leakage, and high volume efficiency.
Smart Button Screen
The functions are concise and clear, the operation is simple, the response speed is fast, the display color is clear, and it is easy to maintain.
Cooling System
Large heat exchange area design effectively prevents high-temperature machines and reduces oil emulsification and coking caused by high-temperature.
Reliable Oil and Air Separator
Vertical tangential cyclone separation structure, complete separation of oil and air, easy replacement of cartridge, and reduced maintenance cost.
Safe and Zero Leakage Connection
Sanzhi has abandoned the traditional low-cost hydraulic hose design. Sanzhi uses High-rigid pipes and flexible joint connections, avoiding bursts typically caused by aging, rubber type 0-ring offers a flexible seal preventing leakage.
Aluminum Intake Valve
The working principle is loaded with electricity, and unloaded with loss of electricity, with the function of unloading and replenishing air, and the function of eliminating the noise of the host. Stable and durable performance, smooth surface and wear-resistant.
Oil Viewing Mirror
Adopting PMMA material, good transparency, high temperature resistance, and small color change, you can visually observe the oil level change and the use of lubricating oil, timely replacement and adding, to avoid the replacement of untimely damage caused by the equipment.
Excellent Air Filter
An air filter with excellent air purification capability ensures a clean air system and three-stage filtration to maximize air purification and meet standard emissions, it can remove a lot of steam and a small amount of dust gas occasions.
Oil Filter
Filtering impurities in the lubricating oil, so that the head gets better lubrication and prolongs the life of the air compressor.
High-Quality Soundproof Cotton
Compact noise reduction housing, achieving no vibration amplitude during operation, cooperates with high-quality soundproof cotton to further improve noise reduction levels.
