石棉矿石选矿最重要任务之一,是生产出具有最高产量和预定质量的各种牌号石棉,为了完成这一任务,必须对石棉精矿分级过程进行控制。石棉精矿分级,是在若干台同类设备上将若干股不同粒度分布的料流按粒度进行分配的多段工艺过程。该过程中包括5～12条生产各种牌号石棉的工艺线。已有文献建议采用改变最后两段流程结构的方式,亦即借助于对倒数第二段作业各股排料进行分配,并改变料流从倒数第二段至末段
One of the most important tasks in asbestos ore beneficiation is the production of asbestos of various grades with the highest yields and predetermined qualities, in order to accomplish this task, the grading of asbestos concentrate must be controlled. Asbestos grade, is a number of units in the same equipment will be a number of units of different particle size distribution of the flow distribution according to the size of the multi-stage process. The process includes 5 to 12 production lines of various grades of asbestos. It has been suggested in the literature that the way to change the structure of the last two stages is to allocate the discharges of the penultimate session by changing the flow from the penultimate stage to the final stage
