某选矿项目新上3.8 m×6.7 m和3.6 m×6.0 m两种溢流型球磨机,球磨机备件种类和数量最多的是筒体衬板,所以设计时将两种不同直径球磨机筒体衬板采用共用与互换。1球磨机及其筒体衬板简介1.1球磨机的工作原理在磨矿工作中,物料通过空心轴颈给入进行粉磨,筒体两端有端盖和中空轴,内装有各种尺寸的研磨体(钢球、钢段、钢棒及砾石等)。当球磨机筒体在传动系统的作用下以一定的转速绕水平轴线回转时,筒体内的研磨体和物料在离心力和摩擦力的作用下,随着筒体内壁上升到一定高度,当它们自身的重力大
A beneficiation project on the new 3.8 m × 6.7 m and 3.6 m × 6.0 m two overflow type ball mill, ball mill spare parts and the largest number of cylinder liner, so the design of the two different diameter ball mill liner Sharing and exchange. A ball mill and its cylinder liner Brief introduction 1.1 The working principle of the ball mill In the grinding work, the material is fed through the hollow journals for grinding, both ends of the cylinder cover and hollow shaft, built with various sizes of grinding body (Steel ball, steel section, steel bar and gravel, etc.). When the ball mill cylinder under the action of the transmission system at a certain speed around the horizontal axis of rotation, the grinding body and material in the cylinder under the action of centrifugal force and friction, as the inner wall of the cylinder rises to a certain height, when their own Gravity
