Description

Quartz sand magnetic separation system Technical Field The invention relates to the field of quartz sand processing, in particular to a quartz sand magnetic separation system. Background In the process of breaking quartz sand, the quality of the quartz sand is seriously affected by the introduction of mechanical iron and subsequent oxidation problems. When the hammer breaking operation is performed, abrasion of the apparatus generates scrap iron, which is introduced into the quartz sand as mechanical iron. Even after the acid washing treatment, part of the mechanical iron remains. Once the residual mechanical iron is contacted with air, the residual mechanical iron is rapidly oxidized into ferric iron, so that the quartz sand is red-yellow, and the purity and quality of the quartz sand are greatly reduced. In addition, if the quartz sand after pickling is not timely dried, when the quartz sand contacts with an iron tool, iron impurities are introduced again, so that secondary pollution is caused. Notably, the mechanical iron particles are very fine and they easily adhere to the surface of the silica sand. This results in poor removal of conventional magnetic separation methods, so that some of the mechanical iron remains in the quartz sand. Moreover, the secondary pollution problem is easy to be ignored, and the oxidation speed is extremely high, so that the color and quality of the quartz sand are influenced in a short time. In order to improve the quality of quartz sand, the problems of mechanical iron introduction and oxidation must be emphasized, and effective measures are taken to reduce the influence of the mechanical iron introduction and oxidation on the quality of quartz sand.
