Introduction to magnetic system modeling of separator

The new experimental prototype of large particles of magnetic separator magnetic system entity model produced by Henan Hongxing crushing machine industry is mainly composed by the yoke and permanent magnet (PM). The model ignores the axial edge effect of the magnetic system and simplifies the ZD model. The external device of Yoke has friction wheel drive. The entity model does not consider the effect of cylinder internal the magnetite powder on the magnetic field distribution and air gap between permanent magnet and the yoke.
Magnetic reel is high permeability soft magnetic material, permanent magnet is with high performance rare earth permanent magnet material NdFeB, its B = r1.25T, Hc = 860k. Rare earth permanent magnet materials demagnetization curve almost has linear characteristics and the slope of the demagnetization curve is almost equal to the permeability of vacuum magnetic, which can also be seen with the reply to the same permeability.
The permanent magnet system has symmetry; the three-dimensional problem can be reduced to the problem of two-dimensional plane. The system contains a brief iron and permanent magnets and the air gap, belongs to the static magnetic field. Solver adopts Mganeotsattci Solver; the coordinate system adopts XY coordinate system.
The permanent magnet adopts high-performance seven permanent magnetic materials. By a large number of simulation calculation to the magnetization direction of the permanent magnet in the model parameters, we finally determine the parameters such as the direction of magnetization of each permanent magnet. The relative magnetic permeability of the air gap taken pr = l.
