Magnetic-field-alterable belt type magnetic separator

Abstract

The invention discloses a magnetic-field-alterable belt type magnetic separator. The magnetic-field-alterable belt type magnetic separator comprises a feeding conveying belt; a quantitative feeding bin is installed above the feeding conveying belt, to-be-separated materials are contained in the quantitative feeding bin and can be quantitatively conveyed onto the feeding conveying belt through the quantitative feeding bin according to requirements, and a magnetic separating conveying belt is installed on the upper portion of the tail end of the feeding conveying belt in the movement direction of the feeding conveying belt; a magnetic-field-alterable magnetic source body is installed in the magnetic separating conveying belt, a tail ore bucket, a middle ore bucket and a fine ore bucket are installed on the lower portion of the magnetic separating conveying belt in the movement direction of the magnetic separating conveying belt, and the to-be-separated materials are attracted by the magnetic-field-alterable magnetic source body and tightly attached to the magnetic separating conveying belt; and in the conveying process of the magnetic separating conveying belt, the magnetic-field direction of the magnetic-field-alterable magnetic source body changes so that the to-be-separated materials with different characters can be dropped into the tail ore bucket, the middle ore bucket and the fine ore bucket correspondingly, and through a low-frequency pulsing-type planer magnetic system, all magnetic-field spaces can be sufficiently used. The ore separating efficiency is greatly high, and manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of ore mining, in particular to a variable magnetic field belt type magnetic separator. Background technique [0002] The so-called magnetic separation is a beneficiation method that uses the magnetic difference of the material to be separated to separate the mineral particles in the separation magnetic field. Magnetic separation can be divided into wet magnetic separation and dry magnetic separation. Wet magnetic separation requires water as the working medium, which is difficult to achieve in areas with severe water shortage, and may cause serious pollution to the surrounding environment; compared with the complex process and application limitations of wet magnetic separation, dry magnetic separation The equipment has many advantages such as simple structure, low investment, low operating cost, energy saving and environmental protection. Therefore, dry magnetic separation has developed rapidly in recent ...

Problems solved by technology

However, this kind of permanent magnet roller has a magnetic field in the range of 360 degrees, so that the manufacturing cost is often very high, but in the actual industrial application, only half or even a small half of it is often used, resulting in A great waste of cost makes this magnetic separation equipment not have a big competitive advantage in the market
