Background
Since the advent of continuous high gradient magnetic separators, they have become an important component of magnetic separation devices, and are key devices widely used in many fields to separate magnetic and non-magnetic substances. In recent years, sorting media used in continuous high gradient magnetic separators have been rapidly developed in various aspects such as media materials, media structures, media arrangements, and the like, and the media cartridge washing methods have been increasingly diversified.
The medium box is a core component of the continuous high-gradient magnetic separator and is one of the determinants of good and bad separation effect. The medium box is generally composed of a medium plate, medium ears and a medium rod, wherein the medium rod is made of magnetic-conductive stainless steel materials, generally round rod-shaped materials and materials with thread structures.
The flushing effect of the medium box has an important influence on the sorting effect of the whole equipment, the good flushing of the medium box can ensure that the magnetic substance and the medium rod are fully separated, the recycling of the medium rod is not influenced, and the moisture content of the discharged material is low. The flushing device of the medium box is generally a hydraulic flushing device, and a high-pressure gas is used for assisting in flushing under the action of hydraulic flushing.
At present, in order to improve the sorting index, the continuous high-gradient magnetic separator generally increases the sorting height of a medium box, so that the sorting action time of the magnetic medium box is prolonged, but some devices cannot improve the sorting height of the medium box due to structural limitation, for example, a vertical ring continuous high-gradient magnetic separator, some devices can improve the sorting height of the medium box, but the flushing and discharging direction of the medium box is parallel to the feeding and discharging direction, and the flushing difficulty is more and more increased along with the increase of the sorting height, for example, a flat ring high-gradient magnetic separator.
For the separation of fine-grained weak magnetic substances, such as quartz sand, feldspar, hematite and the like, sufficient magnetic medium action time and high magnetic field gradient are important guarantees of the separation effect, and good washing and discharging effects are necessary conditions for ensuring continuous and stable operation and no blockage of equipment.
