Crushing and grinding
据调查,我国选金厂多采用颚式破碎机进行粗碎,采用标准型圆锥破碎机中碎,而细碎则采用短头型圆锥碎矿机以及对辊碎矿机。中、小型选金厂大多采用两段一闭路碎矿,大型选金厂采用三段一闭路碎矿流程。
According to the survey, China's gold by jaw crusher are crushed, the standard cone crusher crushing, fine crushing and the short head cone crusher, roller crusher. In the small gold, mostly using a closed-circuit crushing two, large gold by three stages of a closed-circuit crushing process.
为了提高选矿生产能力,挖掘设备潜力,对碎矿流程进行了改造,使磨矿机的利用系数提高,采取的主要措施是实行多碎少磨,降低入磨矿石粒度。
In order to improve mineral production, mining equipment potential, the crushing process was modified, so that the grinding machine utilization factor increased, the main measures taken to implement more crushing and less grinding, reduce the particle size of ore into the mill.
