A screening device for magnetic material processing

Abstract

The invention discloses a screening device for processing magnetic materials. The screening device comprises a shell, a rotary shaft, rotary blades, an induced draft opening and a discharge pipe. A feed pipe is mounted inside the shell, a feeding opening is formed in the feed pipe, a grinding roll is arranged inside the feed pipe, the rotary shaft is connected with a motor, the rotary blades are positioned on the rotary shaft, the induced draft opening is connected with a circulating pipe, a second fan is fixedly mounted on the discharge pipe, a finished product outlet is formed in the lower end of a cyclone separator, and a filter device is arranged on an air outlet. The screening device for processing the magnetic materials has the advantages that the magnetic materials huddled on the surfaces of screen cloth can be stirred by the rotary blades, can be conveyed into the feed pipe again by a first fan, can be scattered under the effects of the grinding roll and can be screened again, accordingly, meshes can be effectively prevented from being blocked, the screening efficiency can be greatly improved, and good service effects can be realized.

Description

technical field [0001] The invention relates to the technical field of magnetic material processing, in particular to a screening device for magnetic material processing. Background technique [0002] Magnetic materials have been widely used in our lives, such as using permanent magnet materials as motors, core materials used in transformers, magneto-optical disks used as memories, magnetic recording floppy disks for computers, etc. According to Dabit Information, magnetic materials are closely related to informatization, automation, mechatronics, national defense, and all aspects of the national economy. It is generally believed that magnetic materials refer to substances that can directly or indirectly generate magnetism from excessive elements such as iron, cobalt, nickel and their alloys. [0003] The size of magnetic powder particles is an important factor affecting the performance of magnetic composite materials, and its fineness determines its value. Therefore, in th...
