Among many coal preparation technologies, the dense medium cyclone coal preparation technology using centrifugal force separation is the most efficient one in the current gravity coal preparation methods. Therefore, it is very important to improve the wear resistance of the heavy medium cyclone in the main washing equipment and prolong the service life of the cyclone. The use of alumina wear-resistant ceramic liner can improve the wear resistance of the heavy medium cyclone.
Wear-resistant ceramic liner is a popular high-performance ceramic, which is widely used in various fields due to its high-cost performance. Combined with the current market demand for coal preparation, it is more suitable to use alumina ceramics as wear-resistant linings for heavy medium cyclones, which can basically meet the requirements of the wear conditions of intermediate cyclones and meet the current actual situation.
The reason why the wear-resistant ceramic liner has such an effect is that the wear-resistant ceramic liner has high-temperature resistance, wear resistance, corrosion resistance, shock resistance, thermal expansion, and contraction resistance, and can also exert high strength and high toughness. Features, through the integrated design, can be easily replaced and installed.
The wear-resistant ceramic liner can work for a long time without falling off. It can run in an environment of 500 degrees Celsius for a long time, and the general working conditions can meet such temperature conditions; under the same conditions, the wear-resistant ceramic lining plate is 10 to 20 times more wear-resistant than ordinary pipes.
The hardness of wear-resistant ceramic products is second only to diamond in the world, which is beyond the reach of wear-resistant steel and stainless steel products. Wear-resistant ceramics are pasted with high-strength ceramic structural adhesive, which ensures long-term operation under high-speed rotation and does not fall off, and ensures the service life of the product.
