In this system, a large number of valves are needed to control the acidic fluid medium, which requires the valve to have high resistance to high temperature hydrochloric acid corrosion and erosion resistance. It is a worldwide problem and has been restricting the development of acid extraction industrial production system. Through the technical breakthroughs, the 11th Institute of the Sixth Institute conquered key technologies such as high temperature pinch valves for fly ash extraction alumina process systems. It is understood that the delivery pinch valves containing solid and liquid particles, powders, fibers, pulp viscosity abrasive and corrosive materials has unique advantages in the mining and metal industry, the mineral processing industry, pulp and paper, chemical The article processing industry, energy industry and other fields have broad application prospects. The successful development of this valve will lay a solid foundation for solving the demand for control valves and industrial production of various specifications and applications of fly ash extraction alumina industrialization system. Having been in brush making industry for more than twenty years, and on the basis of international most advanced brush making technology and our own patented inventions, Haixing brush machines are stable and reliable and have been well accepted by the markets. Haixing brush machines are used to produce all kinds of brushes. 5 axis CNC brush machines are suitable to produce brushes with complex shapes and can achieve a high production output of quality brushes. Clothes washing brushes, dish wash brushes, toilet brushes, paint brushes, car wash brushes, hair brushes, brooms, disc brushes, roller brushes, etc. can be made by our machines. 5 Axis CNC Brush Machine, 5 Axis Brush Machine, High Speed Brush Machine, High Speed Brush Making Machine Yangzhou Haixing CNC Brush Machine Co., Ltd. , https://www.brushmachine.nl
AVIC solves the problem of extracting alumina in the world by fly ash acid method
Recently, the special valves developed by Shenhua Group have passed the acceptance test by 11 of the Sixth Institute of China Aerospace Science and Technology Corporation. The valve is applied to extract alumina powder coal ash industrial systems, but also in the world can be the only medium 160 of the valve used in the limit of a strong acid conditions, technology leading to the international level.
