In 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, and so on, down Improve the efficiency of coal preparation, construction, conservation and efficient coal preparation plant, will keep weakening these issues. 5The design of data used for coal in Henan Shenhuo Coal Mine Co., Ltd. Xuehu the coal preparation plant to provide screening, the first coal quality data collected by the review, correction, and comprehensive, are optional curve. Based on a preliminary set of optional process, the calculations of the quality processes, media and water flow balance, choice of appropriate equipment. The final selection based on equipment and associated equipment plans, conduct workshops on various layout and industrial sites in the overall plan. In addition, the design of production facilities, environmental protection, labor, and other aspects of the quota on. According to the design characteristics of coal. Designed with three-product referral and flotation process, the application process is simple, easy to production management. Mine election of hard coal and more difficult to adapt to the election, simple and efficient design toward dense medium process Coal direction. Keyword : Coal preparation
