Description

Technical Field

[0001] The utility model belongs to the technical field of magnetic separators, in particular to a double-drum dry permanent magnetic separator. Background Art

[0002] Magnetic separator is a kind of equipment which uses magnetic material to separate magnetic and non-magnetic ores. Magnetic separator is widely used in resource recycling, wood industry, mining industry and many other fields.

[0003] The working principle of the magnetic separator is based on magnetic difference, and magnetic minerals and non-magnetic minerals are separated by the action of the magnetic field. In the magnetic separator, magnetic mineral particles are magnetically aggregated under the action of the magnetic field to form "magnetic clusters" or "magnetic chains". These magnetic clusters or magnetic chains are affected by the magnetic force in the slurry, move toward the magnetic poles, and are adsorbed on the cylinder. Because the polarity of the magnetic poles is arranged alternately and is fixed during operation, these magnetic clusters or magnetic chains produce magnetic stirring when rotating, and non-magnetic minerals fall off during this stirring. The "magnetic clusters" or "magnetic lotuses" that are finally adsorbed on the surface of the cylinder are the concentrates.

[0004] Although the existing magnetic separator can use the characteristics of the double drum to separate and classify materials, due to structural problems, multiple operations are required to separate materials with different magnetic properties, which affects the production rate; and the existing magnetic separator has the problem of a high feeding port position, which makes manual feeding inconvenient.
