In view of the environmental problems, it is desirable that the performance of non-ferrous metal recycling system is improved. The challenge facing engineers is making this recycling process economical, especially for the material.Most of non-ferrous metal products consist of plastic and nonferrous metal. Therefore, recycling these components requires the different materials to be separated so that each can be recycled individually.In this study, the experimental study of plastic-nonferrous metal separation has been performed by means of a vibro-electrostatic separator. The separator consists of a vibratory feeder equipped with two plate electrodes. An analytical solution is provided to estimate the recovery of plastic or nonferrous metal. The separation tests were performed on a sample containing 50% polyvinylchloride (PVC) and 50% aluminum. The influence of electric field strength and amplitude of conveying surface on the separation efficiency was investigated. The purity of PVC was 99.18±0.05% at the recovery of 93.11±0.91%. The purity of aluminum was 99.72±0.07% at the recovery of 90.65±0.79%.

鉴于环境问题，有色金属回收系统的性能亟待提高。工程师们面临的挑战是如何使这种回收过程变得经济，特别是对材料来说。大多数有色金属产品由塑料和有色金属组成。因此，回收这些部件需要对不同的材料进行分离，以便每种材料都可以单独回收。在本研究中，利用振电分离器进行了塑料-有色金属分离的实验研究。该分离器由配备有两个平板电极的振动给料机组成。给出了估算塑料或有色金属回收率的解析解。分离试验是在含有50%聚氯乙烯(PVC)和50%铝的样品上进行的。考察了传送面电场强度和电场幅值对分离效率的影响。聚氯乙烯纯度为99.18±0.05%，回收率为93.11±0.91%。铝的纯度为99.72±0.07%，回收率为90.65±0.79%。
