英国瓦莲-斯普林(Warren spring)实验室对这台利用导电性差别的新分选机进行了试验并报导了其试验结果。本文叙述了用于分选颗粒混合矿物的新型分选机。分选过程是根据混合物料中各种矿物导电性的差别。分选机由一个水平旋转的圆盘构成。被选物料给到圆盘上面并且由电晕放电的离子流使物料充电。导电的颗粒很快失掉其电荷并为离心力所抛开,不导电的颗粒保存共所得电荷而附在圆盘上并被刷子刷下。本文还提出了对各种混合物料的试验结果。
The Warren spring lab in the United Kingdom tested the new sorter, which makes use of the difference in conductivity, and reported the results. This article describes a new sorter for sorting granule-mixed minerals. The sorting process is based on the difference in conductivity of the various minerals in the mixed material. The sorter consists of a horizontally rotating disk. The selected material is fed to the disk and the charge is charged by the corona discharge ion flow. The conductive particles quickly lose their charge and are thrown away by the centrifugal force. The non-conductive particles hold the resulting charge and attach to the disk and are brushed by the brush. The paper also proposed the test results of various mixed materials.
