Plate-type electrostatic separators are commonly employed for the selective sorting of conductive and non-conductive granular materials. The aim of this work is to identify the optimal operating conditions of such equipment, when employed for separating copper and plastics from either flexible or rigid electric wire wastes. The experiments are performed according to the response surface methodology, on samples composed of either "calibrated" particles, obtained by manually cutting of electric wires at a predefined length (4mm), or actual machine-grinded scraps, characterized by a relatively-wide size distribution (1-4mm). The results point out the effect of particle size and shape on the effectiveness of the electrostatic separation. Different optimal operating conditions are found for flexible and rigid wires. A separate processing of the two classes of wire wastes is recommended.
板式静电分离器通常用于对导电和非导电颗粒材料进行选择性分选。这项工作的目的是确定这种设备在用于从柔性或刚性电线废料中分离铜和塑料时的最佳操作条件。实验是根据响应面方法进行的，样本由“校准”颗粒组成，这些颗粒是通过将电线手动切割成预定长度（4毫米）获得的，或者是实际机器研磨的废料，其特点是尺寸分布相对较宽（1 - 4毫米）。结果指出了颗粒大小和形状对静电分离效果的影响。对于柔性和刚性电线，发现了不同的最佳操作条件。建议对这两类电线废料进行单独处理。
