试验室XMGQ型功指数球磨机技术参数
Technical Parameters of Laboratory Work Index BallMill
XMGQ功指数球磨机主要用于测定各种矿石、炉渣等物料的磨矿功指数。本产品由原地矿部唯一指定企业生产，执行行业标准。
XMGQ Work Index Ball Mill is mainly used to determine the work index of grinding of ores , slag and other materials. The product is produced by the only enterprise designated by the former Ministry of Geology and Mineral Resources, in compliance with the Industrial standards.
与一般球磨机相同，将一定粒度和重量的物料放入球磨机内，球磨机内装入一定尺寸、一定数量的钢球，在特定转数下进行干法磨矿，将产品筛分、称重，反复进行多次，在经计算得出磨矿功指数（kwh/t）。
As with the common ball mill, materials of given size and weight and steel balls of certain size and number are put into ball mill. Dry grinding proceeds at the rated rotation speed to screen and weigh products repeatedly. The grinding work index （kwh/t）is obtained by calculation.

机器结构概述
Structure
XMGQ型功指数棒磨机主要结构。由主机（包括电动机、减速器、筒体、定位插销等）、接料附件和电气控制等部分组成。
XMGQ work index ball mill is mainly composed of mainframe (including motor, speed reducer, drum, positioning lock pin, etc), receiving accessory, electric control parts, etc.
主机筒衬为整体波浪形，由沉头螺钉固定在筒体一端开口用以进排料。棒磨机在磨矿过程中，如需倾翻角度时将转动手把插销提起，此时拉动定位插销放进相应弧形槽内，转动手把即可进行调整。
The liner plate for mill body is on the whole in the shape of wave. It is fixed at one end of the drum with sunk screws to feed and discharge materials. If a tilting angle is needed during the grinding process of the mill, lift the bolt of turning handle. At this time, pull the positing lock pin and put it into the corresponding arc groove. Turn the handle and adjustment can be made.
