(Center-to-center spacing) is 110 mm, coil radius a '
(Radius to coil center) is 80mm, L'and a '
The ratio is L '/ a' = 1.4.

にはほとんど磁気力が働かないか、あるいは、磁化率が
負の場合には磁気分離ボアの中心方向に磁気力が働く。In the magnetic separation bore 1, a separation target substance 6 having a relatively large magnetic susceptibility and whose orbit is largely changed by a magnetic separation device to be separated, and a non-separation substance 7 having a small magnetic susceptibility or a negative magnetization are mixed. When a separated substance, for example, pulverized coal, is passed by means such as free fall, a magnetic force sufficient to move in the radial direction acts on the separation target substance 6, but the non-separated substance 7
Has almost no magnetic force, or when the magnetic susceptibility is negative, the magnetic force acts toward the center of the magnetic separation bore.

に回収する。As a result, after passing through the magnetic separation bore, the separation target substance 6 is biased to the outside close to the inner wall of the magnetic separation bore, and the non-separated substance 7 is biased to the center side. After that, the respective substances are individually collected by the separated substance collection container 5 and the non-separated substance collection container 4.

する。Here, the non-separated substance 7 having a low magnetic susceptibility or a negative polarity means a substance which is hardly separated by the magnetic separation device without changing its orbit. In the case of pulverized coal, this mainly corresponds to the organic component of coal. The separation target substance 6 corresponds to components such as pyrite, kaolinite, and siderite.
