球磨机筒体衬板相关的几项改进(国外英文资料) Several improvements related to ball mill barrel liner Several improvements related to ball mill barrel liner ???? 1 ball mill and its liner profile ?? The working principle of the ball mill ?? In the mineral processing industry, the axis of the ball mill cylinder body by the regulation of revolution turning, in crushing medium and ore within the cylinder under the action of centrifugal force and friction, as the wall up to a certain height, and then from compared.in free fall or rolling down. The crushing of the ore is mainly through the impact of the crushing medium and the grinding of motion. Ore from the hollow shaft neck at the end of the cylinder to into unceasingly, and grinding the cylinder of the following product at the other end of the hollow shaft neck out unceasingly, the movement of the ore in the cylinder is used continuously gives a person the pressure of ore. ?? The function and selection principle of the ball mill liner ?? The mill liner is designed to protect the surface of the barrel from wearing and controlling the movement of the ball in the cylinder. In general, the uneven surface of the lining has different friction effects on the ball (ball of the ball mill). Uneven degree big called not smooth lining board, the friction coefficient of the ball, the ball charge to ascend higher, which has a large force, so almost all in not smooth at coarse grinding plate; Uneven degree small called smooth lining, low friction coefficient of the ball charge and ball charge to carry knives is low, thereby force is small, so use smooth lining at fine grinding. ?? The ball mill liner is made of high manganese steel, which is usually 50 to 130mm thick. The thickness of the lining board is not easy to is too big, the thick plate, although can prolong the service life of lining board, but will reduce the volume of ball mill, and thus reduce the production capacity of ball mill. ?? Ball mill lining structure should be easy to install and rep
