PAGE \* MERGEFORMATII 摘 要 在选矿作业中，球磨机的磨矿作业是选矿厂整个工艺流程中承前启后的关键性一步，在选矿工艺流程的建设中所占的成本比例很大，因而对球磨机的钻研是十分必要的，我们需要优化球磨机的机械结构，提高其研磨效率，减少成本。 本课题主要是对K2112.00溢流型球磨机进行结构设计，根据K2112.00溢流型球磨机的技术要求，合理地确定设计方案，并对其机械结构进行设计，包括进料部、传动部、筒体等，绘制球磨机的装配图，主要部分的部件图以及零件图。本课题主要是对球磨机的轴承部，传动部和筒体部进行优化设计。了解了球磨机的工作原理和载荷分布的情况，就可简化轴承部的结构，而使用通用件，可以降低球磨机的成本，满足企业的需求。筒体部的优化：改进筒体材料、合理布置筒体衬板、合理选择衬板材料和类型、优化进出料装置等，筒体部的改进可减少进料端与出料端矿浆的泄露，提高球磨机的运行效率，延长使用寿命，降低能耗。通过查阅资料可知，所设计的溢流型球磨机的直径D=2100mm，长度L=3600mm，经过计算可得到球磨机的转速、功率、装球量等自身参数，进而对其传动部进行设计，选择合适的电动机、减速器、相对应的联轴器等，且合理地设计球磨机的齿轮传动结构，并进行校核。可以降低成本，减少能耗，提高经济效益。 关键词：球磨机；结构优化；回转部；传动部 Abstract In beneficiation operations, ball mill grinding operation is a critical step in the entire process in the past and the concentrator, the cost ratio in the beneficiation process of building a large share, so the research is necessary to mill, we need optimization of the mechanical structure of the mill, which increases the grinding efficiency and reduce costs. This topic is mainly on K2112.00 overflow ball mill for structural design, according to the technical requirements K2112.00 overflow ball mill, and reasonably determine the design and the design of its mechanical structure includes a feed unit, drive unit, cylinder, etc., performed mill assembly drawing, part of the main components and parts Drawings. This topic is mainly on the bearing portion, drive unit and the cylinder section mill to optimize the design. Understanding of the situation of the working principle of the ball mill and load distribution to simplify the structure of the bearing portion, and the use of common parts, can reduce the cost of the mill, to meet the needs of enterprises. Optimization of the barrel portion: Improved cylinder material, rational arrangement of the cylinder liner, a reasonable choice of liner material and the type of optimization out equipment, etc. can be reduced to improve the barrel of the feed end and the discharge end of the slurry leak, improve operating efficiency of the mill, increas
