Adjust the distance between the magnetic drum and the dividing plate
The distance between the separation plate and the magnetic drum is an important parameter in the pre-selection process. The smaller the distance between the separation plate, the better recovery of the lean magnetite blocks, which reduces the utilization rate of ore resources;
the separation plate The longer the distance is, the better separation of gangue minerals will not be obtained, and the grade of entering grinding will decrease, which is not conducive to the exertion of grinding efficiency. According to the nature of the ore and adjusting the distance between the dividing plate and the drum, the gangue can be fully thrown out, and at the same time, the magnetic products can be fully recovered and the recovery rate of the dry concentrate can be guaranteed.
Adjust the height of the dry magnetic separator separator
The separator of the magnetic separator directly affects the separation effect of the magnetic separator. The separator is too low, so that the extremely lean magnetite blocks cannot be recovered well, which reduces the utilization rate of ore resources; the separator is too low.
If it is too high, the gangue minerals will not be thrown out completely, which will affect the sorting effect of the dry magnetic separator. Adjust the height of the dry separation material plate according to the specific situation, so that the dry separation can not only ensure a certain proportion of the tail, but also make the non-magnetic minerals better thrown.
Increase the flat feeder, try to make the dry material layer thin and uniform
Generally speaking, the farther the magnetic separator is from the surface of the cylinder, the more the magnetic force attenuates. If the material flow is too thick, magnetic particles and non-magnetic particles will be mixed with each other, which will affect the sorting effect of ore. distribution is ideal.
It is required to increase the material layer leveler before the dry selection, and try to use the effective width of the belt to make the dry selection material layer thin and uniform to ensure the dry selection effect.
