XMGB功能指数球磨机产品介绍
一、用途
I. Application
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**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.
二、工作原理
Ⅱ. Working Principle
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.
