本文专门论述鼓筒式电选机电极的结构,提出应按照矿物通过电场作用区域的时间来设计电极的结构,以满足于使矿粒达到Q_m。时间应大于0.1秒,而小于0.1秒及鼓径太小都不利于分选。据此作者提出的电极形式适应性较好,并在白钨锡石等矿物的分选中获得了良好的效果。 This article is devoted to the structure of the electrode of a drum-type electrodeposition machine. It is suggested that the structure of the electrode should be designed according to the time when the mineral passes through the electric field so as to satisfy the requirement that the ore grain reaches Qm. Time should be greater than 0.1 seconds, while less than 0.1 seconds and drum diameter is too small for sorting. According to this, the electrode has good adaptability to the electrode form and has obtained good results in the sorting of scheelite and other minerals.
