High frequency polyurethane fine screen media is mainly suitable for dehydration of coal slime in coal preparation plants, and can recover 50% to 80% of dry coal in incoming materials. The application of high frequency polyurethane fine screen media in coal washing plants is a major advancement in coal slime recovery technology in the coal preparation industry.

Because of its low investment and operating costs, Make small and medium-sized coal preparation plants and simple coal preparation plants also have the ability to use high frequency polyurethane fine screen media to recover coal slime, which is also conducive to the realization of closed-circuit circulation of coal washing and improves the environment of coal preparation plants.Conducive to the protection of the environment, the high frequency polyurethane fine screen media used in the coal preparation plant to recover coal slime has obvious economic and social benefits. However, with the gradual enlargement of coal preparation plants,the requirements for the technical indicators of high frequency polyurethane fine screen media are also gradually increasing, including the requirements for use effect and processing capacity, so gradually improving and perfecting high frequency polyurethane fine screen media is the goal that everyone has been pursuing.
