1、 I 0.9x3m 中心传动球磨机回转部分设计 摘 要 球磨机在建材行业应用广泛，是目前工业上广泛使用的细磨机械。磨机能粉 末各种硬度的物料，在矿场和发电厂均有应用。球磨机不但在建材工业中广泛应 用，而且在冶金、选矿、化工、电力等工业中也广泛采用. 本次设计为0.9x3m 中心传动球磨机，主要完成回转部分的任务，首先，这 次磨机的隔仓板为提升双层隔仓板， 提升式双层隔仓板有强制物料流过的功能， 即通过的物料是不受相邻两仓物料水平面的限制，甚至前仓的物料面比后仓物料 面尚低的情况下仍可通过物料，可以控制其前后两白的适宜的“料球比” （该仓研 磨体质量与仓内存料质量之比） 。因此，它适合安装在干法

2、磨的粉碎仓。第二，该 磨机为两端主轴承支撑，润滑方式采用静压启动，动压润滑的原理，这样可以降 低启动转矩，节约能耗，降低成本。第三，磨机衬板的材料为高锰钢，它具有一 定的抗冲击韧性，这样大大衬板的硬度和耐磨性。 关键词关键词：球磨机 ，提升式隔仓板，主轴承，动静压润滑，高锰钢 II 0.9x3m Center ball slewing part of the design ABSTRACT Ball mill is widely used in building materials industry , is currently widely used in industrial grindi

Second, the ends of the main bearing support for the mill , lubrication hydrostatic started hydrodynamic lubrication theory , which can reduce the starting torque , save energy and reduce costs. Thirdly, the mill liner material for the high manganese steel, it has a certain impact toughness , which greatly liner hardness and wear resistance .
