iron ore magnetic separator line periodic inspections can not be ignored



Affect magnetic separator magnetic effect is the most important factor is fed into the separator feed size. The thickness of the ore particle size for most minerals, it marks the separation of ore monomer

The size of the magnetic particles and gangue mineral particles degree of separation. If you give into the ore particle size is small, indicating high mineral separation monomer can obtain satisfactory sorting index; such as

If the ore fed into the relatively magnet plates coarse particle size, indicating that no sufficient dissociation mineral monomer separation is not high, many of the living body that is opposite to the magnetic particles and gangue remain a considerable portion of Results

Together. As with the living body also has a considerable magnetic sorting can choose up for a considerable part of that concentrate grade decreases. Magnetic separator magnetic separation is achieved

Necessary conditions. Uniform magnetic field and the magnetic field can be divided into non-uniform magnetic field, the magnetic field non-uniformity degree of said gradient, the gradient of the magnetic field strength of the magnetic field along the space variable

The rate, the unit length of the magnetic field strength variation. Magnetic field gradient is larger, the greater the degree of unevenness of the magnetic field, which is the rate of change of magnetic field strength along the large space. Magnetic

Suffered magnetic mineral particles size, the magnetic field intensity and the magnetic field gradient is proportional to the product. If the magnetic field gradient is equal to zero (uniform magnetic field strength regardless of how high, the magnetic field

Gradients are equal to zero). Suffered by the magnetic force is zero mineral particles, the magnetic separation can not be performed. Therefore, the magnetic Xian machines are using inhomogeneous magnetic field.

According to the principle invented magnetic reunion reunion re-election of the magnetic beneficiation equipment and magnetic columns are approximately uniform magnetic field in the environment for sorting. Its principle is to use the recoil water

Fluidization method for grading reunion reunion magnetic material and non-material non-magnetic separation. Impact separator sorting factor with magnetic separator magnetic pulley related magnetic pulley

Generally used in ore crushing coarse broken, and the final product into the mill before sorting on. Main role is to get rid of unwanted waste, improve access mill ore grade,

Reduction into the mill grinding machines, thereby reducing the cost of grinding. To know the whole dressing grinding production costs as a proportion of 60% to 70%, while the dry magnetic pulley can be pre-selected

Throw away the tail first mineral rate to 20% up to 15%.

Magnetic separation principle is to be elected to the other material into magnetic separator sorting space, by force and other mechanical forces (such as gravity, centrifugal force, friction, medium resistance, etc.)
