According to the preliminary estimates from Henan Hongxing Mining MachineryCo., Ltd., when Chinas coal selection rate increased by one percentage point,the linear vibratingscreen industry can get market share about $ 100 million calcium carbonate limestone machine. The nature of coaldetermines the high precision of the vibrating screen used in coal screening.Coal is difficult to be screened, therefore, the high frequency vibratingscreen used in coal industry must has high quality, excellent performance,high precision, etc. The high frequency vibrating screen with sieve surfacewidth more than 3 meters is the most difficult to be manufactured.With thedecline of recent growth rate of overall demand for coal market, major coalenterprises will enhance the coal washing rate coal single roll crusher, and make upgrade product qualityas an important task, which also provides market opportunities for thedevelopment of mobile crushing and screening plant industry. The vibratingscreen enterprises should develop into standardization, serialization, universaldirection, high efficiency and high yield. Only increasing scientific andtechnological innovation and enhancing competitiveness can gain a firm footingin the market of mobile crushing and screening plant which is in a growingdemand for high efficiency and high precision.According to Chinas coalproduction in recent years hammer mill with cyclone, Chinas coal output will reach 4.64 billion tons inthis year, so its expected that the demand value of screening equipment will be5.41 billion Yuan, of which the demand value of large linear vibrating screenwill be 4.519 billion Yuan. Faced such a large market demand, the high-endvibrating screen used in coal industry is still monopolized by a few domesticand foreign brands. With the introduction of foreign advanced productiontechnology and their own technological innovation, domestic enterprises have gotfruit from international high-end coal market.
