毕各庄 4.0Mt/a 选矿厂设计摘 要本设计任务为唐山毕各庄矿井型 4.0 Mt/a 选煤厂，毕各庄是隶属于开滦集团的矿井型选煤厂。首先根据生产大样和浮沉试验资料的分析与综合，绘制可选性曲线；根据原煤的性质及精煤质量要求等,评定原煤为难选煤。在进行选煤方案比较的基础上，确定采用重介-浮选联合流程的选煤方法，并制定了工艺流程；然后经过工艺流程计算、设备选型，对主厂房和总平面进行布置，并进行了图纸的绘制。同时做出了该厂的经济技术分析，可知该设计实用性较高。关键字：难选煤；重介-浮选；设备选型；工艺布置 Bige Village 4.0 Mt/a concentrator designAbstractThis is a process design for the 4.0 Mt/a type mine of coal preparation plant in Bige Village of Tangshan. Bige Village attaches to the mine-model coal preparation plant of KailuaGroup. First of all, according to the production details and analysis and synthesis of fugitive dust test data, draw the washability curves, Washability curve drawing;According to the nature of the raw coal and plant quality requirements, etc., to evaluate the raw coal in coal. On the basis of coal preparation scheme comparison, Determine the dense media - flotation coal preparation method of the joint process, And formulate the process flow; And then through the process calculation, equipment selection, the main plant and total plane layout, and drawing the map. At the same time made the plant's economic technical analysis, practicality is higher, the design. Key words:difficult separation coal; The heavy – flotation; Equipment selection; Process arrangement目 录摘 要...............................................................IABSTRACT............................................................II第一章 设计概要...................................................11.1 项目背景......................................................11.2 可行性研究概要................................................11.2.1 原...
