Embodiment Construction

[0016] The present invention will be further described below in conjunction with accompanying drawing.

[0017] Depend on figure 1 , figure 2 It can be seen that in a magnetic separation method, the material rotates in the magnetic field with the sorting drum in the sorting drum, and the material is subjected to the combined action of magnetic force, gravity and centrifugal force, and the magnetic material and non-magnetic material are layered and adsorbed on the sorting drum. The inner wall realizes the separation of magnetic materials and non-magnetic materials under the joint action of rinsing water, flushing water and the slope of the sorting drum.

[0018] The gradient of the sorting drum of the present invention is 6°-20° (8° in this embodiment).

[0019] A kind of magnetic separator that realizes above-mentioned magnetic separation separation method, it comprises frame 2, power 1, feeding device 11, unloading device 4, magnetic system 9, on frame 2 is provided with b...

Abstract

The invention discloses a magnetic separating method for improving the recovering effect of the fine-grained magnetic materials, which is characterized in that the materials rotate along with a separating drum in the separating drum and are separated under the common action of rinse water, wash water and the gradient of the separating drum. A magnetic separator for realizing the method is characterized in that a rack [2] is provided with a magnetic system [9] and the separating drum [8] driven by power [1], the included angle between the separating drum [8] and the horizontal plane is 6-20 degrees, a feeding device [11] is arranged on the upper part of the front end of the separating drum [8] and a discharging device [4] is arranged on the lower part of the tail end of the separating drum[8], a rinsing water pipe [5] and a washing water pipe [10] are arranged in the separating drum [8], a material receiving chute [7] is arranged below the washing water pipe [10] and is connected withthe discharging device of the magnetic materials. The method of the invention is feasible, the equipment is simple, the purity of the magnetic materials is improved by 10-20% and the yield is improvedby over 10%.

Description

Technical field: [0001] The invention relates to a method and equipment for separating solid materials from fluids, in particular to a magnetic separation method and a magnetic separator. Background technique: [0002] Magnetic separator is a magnetic separation equipment widely used in industry. According to the difference in the specific magnetic susceptibility of the materials to be separated, it realizes the separation of minerals with large magnetic properties and minerals with small magnetic properties. According to the specific magnetic susceptibility of various minerals, magnetic separators are divided into weak magnetic separators (mainly used for sorting ratio magnetic susceptibility greater than 70000×10 -9 m 3 / Kg strong magnetic minerals, such as magnetite, vanadium-containing titanium magnetite, etc.), medium magnetic separator (mainly used for sorting ratio magnetic susceptibility greater than 100×10 -9 m 3 / Kg medium magnetic minerals, such as ilmenite, c...
