    摘要
    打散分级机是九十年代初问世的新型料饼打散分选设备,集料饼打散与颗粒分级于一体,与挤压机配套使用,可以消除挤压粉碎机边缘漏料和开停机过程中及正常工作时未被充分挤压的大颗粒对后续球磨系统产生不利的影响,以获得大幅度增产节能的效果。打散分级机利用离心冲击破碎原理对物料进行打散,利用惯性及空气动力学原理对散状物料实现分级。
    为了提高挤压预粉磨工艺系统的产量,将更多的粉磨功移至磨外由挤压打散回路承担,提高入磨物料的粒度和易磨性,本课题设计了水泥粉磨系统中挤压磨后续设备打散分级机。整台打散分级机采用整体紧凑设计的方法,降低了占据空间,且提高了打散和分级的效率。根据打散分级机的工作要求,采用工序高度集中的原则,确定了打散分级机的整体传动方案,应用最优化的方法设置了打散盘及风轮的转速,分析计算了系统的运动和动力参数确定了传动比。进行了电动机的选择、带轮的设计、轴的结构设计、轴的强度校核、键连接的选择计算、滚动轴承的类型代号选择、轴承的寿命计算、联轴器的选择计算。在此方案的基础上还进行了改进设计,将双传动拆开,这样优化了轴的设计,提高了系统的稳定性。

    Abstract: Scatter grading device is the new blank cake which is published at the beginning of the 90's hits the divergence to choose the equipment, the aggregate cake to scatter with the size grading in a body, with the extruder necessary use, it may eliminate the disadvantageous influence extrusion grinder edge funnel and opens in when the engine off process and the normal work the big pellet which fully extrudes to the following grinding system has not been produced, which obtains the effect of the large scale production increase energy conservation. Scatter grading device carry on using the centrifugal impact crash principle to the material scatters, to disperse the shape realization graduation using the inertia and the aerodynamics principle.
    In order to improve the grinding process system extrusion production, will more grinding work moved to the ground by extrusion scattered for loop, improve the grain size and material into the grinding mill sex, the subject of cement griding system design in grinding follow-up equipments scattered extrusion sorting machine. The whole machine by whole grade machine scattered compact design method, reduce the occupy space, and improve the efficiency of the scattered and classification. According to the classification of the machine work requires scattered, the process of the high concentration of principle, determined the classification of the whole machine scattered transmission scheme, the application of optimization methods set the speed of the rotor disc and scattered, calculating the system of sport and dynamic parameters determined the transmission. The choice of the motor, with the design of the shaft, wheel shaft structure design, the intensity, key link choice calculation, rolling bearing type selection, bearing life code calculation, the choice of the coupling calculation. On the basis of this project was the design improvement, will double drive apart, so the design of optimized shaft, improve the stability of the system.
