Experts put forward that in order to achieve good magnetic separation effect, the factors affecting the magnetic efficiency of the magnetic separator, must avoid, to improve the factors affecting the magnetic separator as far as possible, every magnetic separator equipment to do a good job.So what factors affect the magnetic efficiency of the strong magnetic separator?How to avoid these factors?
Here are some answers from our experts:
There are two kinds of magnetic field uniform and uneven, magnetic separator magnetic field uneven degree is generally expressed by magnetic field gradient, magnetic field gradient is the rate of change of magnetic field intensity along space, that is, the change of magnetic field intensity per unit length.The greater the magnetic field gradient is, the greater the degree of non-uniformity of the magnetic field is, that is, the greater the rate of change of magnetic field intensity along space is.If the pursuit of high magnetic field intensity and ignore the construction of magnetic field gradient is obviously a very low-level mistake.The magnitude of the magnetic force on the magnetic particle is proportional to the product of the magnetic field intensity and the magnetic field gradient.Suppose the gradient of the magnetic field is zero.Then the magnetic force on the magnetic particle is zero, magnetic separation can not be carried out.So magnetic separators must avoid gradient fields.
Secondly, it is necessary to ensure the movement state of mineral materials in the magnetic separation process, so as to capture magnetic minerals favourably. For example, when a magnetic mineral slowly enters the magnetic field of a strong magnetic separator, the mineral will be easily sucked away and less missed.However, if the speed is too fast, the inertia will cause the minerals that could be absorbed to miss the magnetic field, thus missing some, and the good effect will not be achieved.
The last is the particle size of the magnetic field into the strong magnetic separator, if the mineral particles are larger, containing more non-magnetic minerals than magnetic minerals, it is difficult to reach the strength of the magnetic field, which leads to suction, will enter the ranks of tailings, so as to waste.However, if the magnetic mineral is larger than the non-magnetic mineral, although it can be sucked away, it also has more impurities in it, thus reducing the metal grade.So what size of mineral material is suitable for magnetic field, which is not good.
Still have is the magnetic force of strong magnetic separator size, some equipment in use after a period of time will reduce the magnetic field strength, so it will make the magnetic field force is not enough, thus missing some small magnetic minerals, affect the magnetic separation effect.Weifang Guote Mining equipment welcomes your arrival.
