The thickening or classification equipment of the aforementioned old inclined plate ( inclined tube) relies on the shallow subsidence to shorten the falling distance and falling time of the particles, which can significantly improve the handling capacity of per unit area of the equipment that once formed a high tide of the promotion and application at home and abroad. However, with the extension of the usage time, the drawbacks of such devices are gradually becoming apparent, which mainly show uneven fabric between the board. In addition, the bond slime on the board can not decline freely so that the gap between the boards is blocked, which affect the normal production until it can not be used.
The main reasons are the followings. First, the inclined plates fail to form an independent operating unit and channel. The way of feeding and nesting are both open, which can not ensure that each plate has the same hydraulics characteristics. Second, the material is subpar. Most of the material is steel, glass or plastic plate whose surface is rough which is easy to bong slime. Third, the structure of the device is complex. It can not be integrated according to the requirements. The manufacturing, installation and use is inconvenient. Forth, the plate spacing is too large, but the length of the plate is too small, which causes that the shallow subsidence utility is limited. In the late 1980s, the popularization and application of these devices is from slow to standstill. After many years” research and application, Henan Hongxing Mining Machinery independently researched and developed KMLF tilting narrow upflow classifier and it was successfully applied in 1999 in the titanium plant. In a complete stone crushing plant, it is equipped with a series of crushing machines and assistant equipment, such as vibrating feeder, jaw crusher, impact crusher, cone crusher, belt conveyor and vibrating screen etc.
At the time of encouraging the development of energy-saving building materials industry, our country also increase the adjustment of mining machinery, strengthening energy conservation, efficient and environmentally friendly crusher equipment, which will also become the leading direction of the crusher industry in the future. In order to face the strong momentum of building materials industry, Hongxing machinery emphasizes on enhancing product quality and optimizes the product and accessory structures with design principles of long-service- life, low power consumption and easy-to-operate, the productions are characterized of dust extraction, low noise and low energy consumption, and operate efficiently and economically.
