The prerequisite for the application of PTMS magnetic separator is that the ore particles to be separated must have a suitable lower and upper particle size. This separation method is mainly determined by the specific gravity of the ore particles, and the influence of the particle size and shape of the ore particles is small, so the separation accuracy is relatively high, and the mineral with a small specific gravity difference (such as 0.1) can be selected; The size range of the selected material can be very wide and the processing capacity is large.
Because the particle size is very small, especially when the specific gravity of the particle is close to the specific gravity of the heavy medium, the settling speed of the particle is very small, so the separation process is very slow, and the separation efficiency will be greatly reduced. PTMS magnetic separator In industrial production, in order to ensure a faster speed and higher accuracy of particle separation, the particle size limit is limited, that is, the particle size can not be too small.
Therefore, the fine parts are often sifted out before the heavy media PTMS magnetic separator is applied. At present, the minimum particle size of metal ores is generally 2-3 mm when using heavy media beneficiation, if the heavy media cyclone is used, the minimum particle size can be reduced to 0.5 mm.
