Combined magnetic separator

This machine combines advantages of the cylinder-type machine and roller-type machine. The separation grain size is effectively expanded. Before separated, objective minerals are classified by screening and only separation-appropriate minerals are then be conveyed to the magnetic separator, to effectively control concentration of the objective minerals prior to separation and accordingly greatly increase separation efficiency. At the same time, the mine filed reduces occupations of crushing and screening facilities, playing an important role for increasing the whole economic benefits of the mine field. This machine is the best model for separation of magnetic minerals with a grain size of 0.1-0.14mm and also one of currently highly-demanded models. According to structure, this model is divided into face-to-face and back-to-back types, according to arrangement of rollers, it is divided into one-cylinder three-roller, one-cylinder four-roller, and four-roller types, and according to discharge, it is divided into integrated concentrate type and integrate tailings type.
