30万吨/年石墨原矿选矿厂工艺流程设计(含CAD图)(任务书,开题报告,设计说明书15000字,CAD图纸5张)
摘  要
选别石墨的方法有重选、电选、浮选这三种方法，浮选是最常用的方法。对国内外浮选石墨的工艺进行了解，对浮选设备、浮选药剂的一些工艺进行研究研究。最后根据石墨性质以及所给的条件查阅相关资料，确定了30万吨/年石墨选矿厂的工艺流程。选矿厂的原矿品位α=3.83%，精矿品位β=91.91%，精矿总回收率ε=85.12%，对石墨精矿选矿生产线进行设计。根据这些数据进行计算，推出原矿的处理量，同时结合工作制度来确定破碎车间和磨浮车间日处理量。根据原矿和破碎后的最大粒度，计算破碎比，最终确定选用两段一闭路的破碎流程，筛分之后细粒度的矿物要送入入磨浮车间进行磨矿浮选。粗磨之后，再进行粗选，如此重复选别五次。根据每天的处理量，计算各段的矿量以及水量和矿浆量，画出数质量流程图和水质量流程图，根据它们以及磨矿细度，产率等各段选矿对产物的要求，来对磨机的磨矿时间和浮选机的浮选时间判断，对设备类型进行选择；根据各段的处理量，对各设备的型号和规格进行选择。

Abstract
In this paper, the method of flotation of graphite made brief introduction, gravity separation, electrostatic separation, flotation of the three methods, of course, now used up is flotation. The technology of flotation graphite at home and abroad is introduced, and some process of flotation equipment, flotation reagents and the protection of graphite chips. Refer to the relevant information according to the properties of the graphite and the conditions given, the technological process of the 10,000 tons / year graphite concentrate concentrator. The ore grade taste alpha is 3.83%, the concentrate taste beta is 91.91%, the total recovery rate of epsilon is 85.12%, and design of mineral processing production line of graphite concentrate.Launch the handling capacity of ore based on these data, combined with the concentrator of the system and determining the amount of daily processing of crushing and grinding and flotation workshop for workshop. First according to the maximum particle size of the ore, and after the crushing of the maximum particle size calculated broken ratio, determine the selection of three sections of a closed-circuit crushing process, the screening fine-grained minerals into grinding and flotation workshop, grinding flotation. Enter the floating mill workshop first minerals for coarse grinding, coarse grinding after roughing, after regrinding, a total of five times. According to the daily handling capacity, sections of the quantity and quality, the water quantity and pulp volume was calculated and draw the flow chart of the number of quality and the quality of the water flow chart, according to them and segment processing product requirements, such as grinding fineness and yield of the mill grinding ore time as well as the flotation machine flotation time to judge, and the equipment type selection; according to the processing capacity of the paragraphs, the equipment models and specifications.
Keywords: mineral processing design; graphite ore dressing; production process; equipment selection.
