This request fully uses these limited the new coal preparation plant, alteration, extension, it is necessary to continuously optimize the coal preparation process, a reasonable choice of advanced coal preparation equipment, determine a reasonable layout of the factory workshop, and choose suitable for coal preparation plant management methods is the only way for coal ,largescale,simplified process flow preparation technique in the future focus of development. The design based on the raw data analysis in Xiegou coal preparation plant source book, design a rational process, Xiegou coal is extremely difficult preparation, so the design referred a threeproduct flotation process, after the mud is taken , mm into the threeproduct cyclone separation, the products is coal and gangue. Less than mm particle and magic separation tailings into the flotation of separation. the application process is simple, easy to production management. By calculating and selecting suitable equipment, and workshops on the proper layout. Finally, the industrial site where the overall planning, Various segments of production and production processes and auxiliary facilities between constitutes an anic whole. In addition, the design is also electrical, drainage, heating ventilation and other areas discussed.
