Abstract

The invention relates to a magnetic reselection device, in particular to an electromagnetically-focused concentration machine for concentrating magnetite, which comprises an ore supply hopper, an ore supply pipe, a tailing overflowing groove, a separation bucket, excitation coils, a water supply package, an ore concentrate funnel and an ore concentrate discharge valve. The separation bucket is internally provided with a plurality of layers of excitation coil with a waterproof ware-resistant protection layer from top to bottom by a bracket, the excitation coil at the upmost layer supplies a constant direct current, other excitation coils are grouped and sequentially switched on with the switching-on time and currents automatically or manually adjusted according to the overflowing density and the separation conditions, the upper part of the separation bucket is provided with a tailing overflowing density sensor, and an ore concentration density sensor is arranged between the ore concentrate funnel and the ore concentrate discharge valve at the bottom of the separation bucket. In machine, the utilization rate of the magnetic field is greatly improved, and lower-cost iron materials can be adopted for the separation bucket. By the aid of the control of the ore concentrate discharge valve, the circulating time adjustment of the separation magnetic field and the automatic control of the field strength, the aims of decreasing the manufacture cost of the device, saving the energy and ensuring the optimal separation effect are achieved.

Description

Technical field [0001] The invention relates to a magnetic gravity separation equipment, in particular to an electromagnetic concentrating concentrator for beneficiating magnetite. Background technique [0002] At present, the gravity separation equipment of the magnet concentrator mostly uses magnetic agglomeration gravity separator, magnetic separation column, etc. The magnetic field of the magnetic agglomeration gravity separator is generated by the permanent magnetic material in the separation barrel. The magnetic field is fixed, not easy to adjust, and the separation effect is poor. The magnetic field of the magnetic separation column is generated by the coil outside the separation barrel, which can adjust the alternating magnetic field and the magnetic field strength. The separation effect is good, but only part of the magnetic field enters the separation barrel, and the utilization rate of the magnetic field is low. Magnetically permeable stainless steel material, high co...
