Embodiment

[0019] a. Use the jaw crusher to crush the ore to a diameter of Φ30-40mm;

[0020] b. Grind the obtained ore to 100 mesh through a centrifugal vibrating mill with a model number of 2MGZ450, so as to disintegrate and peel off the continuous ore powder particles;

[0021] c. Use iron ore dry powder magnetic separator to select iron fine powder. Such as figure 1 As shown, the dry powder magnetic separator is provided with four consecutively connected magnetic separation devices on the frame; the magnetic separation device includes a magnetic separation roller and a logistics plate; A fixed shaft 4 is arranged on the fixed shaft 4, and a roller 5 is connected to the fixed shaft 4 through a bearing. On the fixed shaft in the roller, an electromagnet 3 with a fan-shaped cross section is arranged in the axial direction, and the electromagnet and the roller are electrically connected with the controller; The rotation is driven by the power transmission device. The rotation speed of...

Abstract

The invention discloses an iron ore dry powder magnetic separation process and equipment. The process steps are: a. using a jaw crusher to crush the ore to a diameter of Φ30-40 mm; b. grinding the obtained ore to 100 meshes to disintegrate the continuous ore ore powder particles; c. utilize the iron ore dry powder magnetic separator to select the iron fine powder; device; the magnetic separation device includes a magnetic separation roller and a logistics plate; the magnetic separation roller is provided with a fixed shaft on the frame, and the fixed shaft is connected with a roller through a bearing, and the fixed shaft in the drum is axially An electromagnet with a fan-shaped cross section is provided, and the electromagnet and the roller are electrically connected to the controller; axial ribs are arranged on the surface of the roller; the logistics plate is an arc-shaped plate, which is arranged on the outside of the roller, opposite to the electromagnet , a feed baffle is set on the top of the logistics plate; an iron powder discharge belt is set under the magnetic separation roller.

Description

technical field [0001] The invention relates to an iron ore separation method and equipment, in particular to an iron ore dry powder magnetic separation process and equipment. Background technique [0002] In the existing iron ore wet separation technology, although wet magnetic separation can meet the technical requirements, it requires the factory to be established in a place with sufficient water source, and for the mining area lacking water, it is impossible to use wet magnetic separation to obtain high precision. of iron powder. Contents of the invention [0003] The purpose of the present invention is to provide an iron ore dry powder magnetic separation process to be used in an anhydrous mining area to obtain qualified iron fine powder with a grade up to 66%. [0004] Another object of the present invention is to provide an iron ore dry powder magnetic separator to solve the difficult problem of mine development in arid and water-deficient areas. [0005] The pres...
