Along with the development of technology of ore dressing, reform and innovation of magnetic separator adopts micro-difference parallel magnetic circuit technology, magnetic department has some features, such as small volume, light weight. Magnetic field of magnetic separator uses two kinds of magnetic materials: one is low magnetic properties, the relatively large volume of permanent magnetic material as auxiliary pole, another is high performance, small volume as base.

The magnetic property of two kind of permanent magnetic materials are above10 times difference, so how to use complex is very important. The general method often caused the material waste, flux leakage increased of magnetic separator, low working point of magnetic field, and poor stability. If we use the new focus, directing assembled magnetic technology to combine with the permanent magnet materials, so that to make its working point in the best state.

Along with the progress and development of science and technology, magnetic separator can just adapt to changing circumstances as long as it is constantly updated, so Henan Hongxing Mining Machinery Co., Ltd has done various research about magnetic material, magnetic field characteristics, structural parameters, frame design, magnetic optimizing system of wet permanent magnetic separator. The main contents are:

1.The magnetic materials

We need to research the magnetic performance of permanent magnetic material with different rare earth, and do some comparative analysis, then we can select the appropriate magnetic materials of wet permanent magnetic separator.

2. The assembly process

The large permanent magnetic separator need to the larger size and magnetic structure, so we need the special mechanical processing, the bond and the assembly process if we want to make up the larger group of magnetic and magnetic structure, so we can ensure that requirements of magnetic performance and use about the permanent magnetic separator.

Dry magnetic separator's magnetic circuit of Hongxing Machinery is composed offew magnetizer, more permanent magnets and work space. The prominent characteristics of magnetic circuit is: the complete close working condition, low magnetism leakage, stable magnetic field , the large work space, and three magnetic area with the weak and middle strong. Magnetic Separator (http://www.china-hxjq.com/p56.html) also has some advantages, such as small volume, light weight which is easy to realize the large-scale washing, good stability of magnetic circuit.
