Abstract

The expanding role of electrostatic separation as applied to mineral, agricultural and other related fields is covered. Novel and existing forms of electrostatic separation are classified in two broad forms, separation of charge particles and separation of neutral particles. Two forms of industrial machinery for separating charged particles are presented, one by surface conductivity and the other by enhanced triboelectric differences. A recently developed multifield technology is presented for dielectrophoretic electrostatic separation of neutral particles with differences in particle polarizability. The basis for each form of separation is discussed along with examples.<>

干法静电分离颗粒物料
介绍了静电分离技术在矿产、农业和其他相关领域的应用。新的和现有的静电分离形式分为两大类:带电粒子的分离和中性粒子的分离。提出了两种分离带电粒子的工业机械,一种是通过表面电导率,另一种是通过增强摩擦电差。介绍了一种新发展的多场电介质分离技术,用于分离具有不同极化率的中性粒子。讨论了每种分离形式的基础,并附有示例。
