Problems solved by technology
In the middle of the air-permeable plate, there is a diversion groove whose edge is higher than its surface and is isolated from the air chamber. The airflow blocked by the magnetic system flows to the lower end of the air-permeable plate through the diversion groove under the action of the exhaust port to ensure the fluidity of the material. ; Solve the problem that due to the limited space between the air-permeable plate and the magnetic system, the airflow ejected from the middle part of the air-permeable plate is blocked by the magnetic system and forms a positive pressure above the material, and the fluidity of the material in the middle of the air-permeable plate decreases, which affects the selection of equipment Technical issues with effects

Abstract
The invention discloses a feeding device of a dry magnetic separator, belonging to the field of magnetic material separation equipment. The feeding device of the dry magnetic separator comprises an air chamber arranged on a shell; a breathable plate is arranged above the air chamber, and is arranged on the upper surface of the shell in an inclined way, so that a working surface is formed; the high end of the breathable plate is provided with a feeding hole, and the low end of the breathable plate is provided with an air suction hole communicated with the air chamber; the shell is provided with a vibration device and an air inlet communicated with the air chamber. According to the feeding device of the dry magnetic separator, material is highly dispersed, so that the magnetic material is more easily sorted; the fluidity of airflow in the sorting space is guaranteed, so that the material is prevented from stacking; the angle of inclination of equipment can be flexibly adjusted according to the particle sizes of the material, so that the feeding device is wide in application scope.
Description
technical field [0001] The invention relates to the field of magnetic material separation equipment, in particular to a dry magnetic separator suitable for fine-grained magnetic material separation. Background technique [0002] In recent years, with the development of grinding technology, the high-pressure roller mill based on the principle of material bed grinding has been widely used in the field of ore grinding, and has achieved obvious effects of increasing production and saving energy. Since the minerals rolled by the high-pressure roller mill produce a large number of microcracks, after being fully dispersed and classified, they have the separation conditions of "dry separation and dry throwing", which can effectively reduce the processing capacity of the subsequent process, so it has been rapidly obtained in the mineral processing field. development of. However, the materials processed by the high-pressure roller mill often form cakes, and there are phenomena that t...
