在闭路磨矿过程中,需要根据工艺的要求,将分级溢流浓度保持在规定范围之内,经常用人工去采样测量和调整。人工操作,往往不及时、不准确,使浮选过程不能稳定地进行,选矿指标不能很好提高。控制分极溢流浓度要用很大人力,一般一个磨矿机粗(球磨机和分极机)要一名工人操作。如果解决了溢流浓度的自动指示和调节,一个人就可以操纵几个机组。
In closed-circuit grinding process, according to the requirements of the process, the grading overflow concentration should be kept within the specified range, often by manual sampling and adjustment. Manual operation, often not timely, inaccurate, so that the flotation process can not be stable, beneficiation indicators can not be well improved. Control of the concentration of extreme overflow to use a lot of manpower, usually a rough mill (ball mill and pole machine) to a worker operation. If you solve the automatic indication of overflow concentration and regulation, a few people can manipulate a few units.
