在加工食品或工业产品等高粘度流体的工厂中，需要去除来自生产线管道的金属磨屑。在这项研究中，我们开发了一个高梯度磁分离（HGMS）系统，该系统由超导磁体和磁过滤器，以去除金属磨屑。以粘度系数为1 Pa的聚乙烯醇（PVA）为模型物质，进行了颗粒轨道模拟和磁分离实验。S.结果表明，通过对过滤网目数、流速和过滤器数量等实验条件的优化，可使分离效率达到80%以上。
It is necessary to remove the metallic wear debris originating from pipe of manufacturing line in industrial plant processing highly viscous fluid such as foods or industrial products. In this study, we developed a high gradient magnetic separation (HGMS) system which consists of superconducting magnet and magnetic filters to remove the metallic wear debris. The particle trajectory simulation and the magnetic separation experiment were conducted with polyvinyl alcohol (PVA) as a model material of which viscosity coefficient was 1 Pa. s. As a result, maximum separation efficiency over 80% was achieved by optimization of experimental conditions such as mesh number, flow velocity and the number of filters.
