The present invention provides a sorting device and a sorting method for sorting a magnetically attractable substance and a non-magnetically attractable substance from a sorting target using a high gradient magnetic separator.

Sorting device and sorting method

To provide matrix for magnetic separator capable of sorting magnetic and non-magnetic particles highly accurately and efficiently and enabling previous simulative recognition of correct magnetic force distribution in matrix space, and magnetic separator. Matrix for magnetic separator of present invention includes: entirely approximately wavelike plate-shaped magnetic walls each having orderly structure of wave-shaped bent sections continuously repeatedly formed in wave advancing direction and each having wave height h of &#x2266;1 mm and approximately inverted V- or U-shape; and entirely approximately box-shaped housing part housing magnetic walls and having in opposite surfaces, introducing and discharging parts through which sorting target fluid containing magnetically-attractable substance magnetically-attractable to magnetic walls is passed thereinto/therefrom, magnetic walls arranged in juxtaposition such that convex shapes of wave-shaped bent sections in one magnetic wall face concave shapes thereof in another magnetic wall adjacent to one magnetic wall with constant interval therebetween.

Matrix for magnetic separator and magnetic separator

An airflow separator of the present invention includes: a first column into which gas is introduced from a lower portion and inside which a sample is made to flow; a heavy particle recovery device provided at the lower portion of the first column; and a control device configured to control a wind speed by an amount of gas to be introduced into the first column. The first column has a weak rotational airflow generation mechanism to smooth wind speed distribution in a cross-section of a tube of the first column by making it substantially W-shaped from a portion of a wall of the tube to the center of the tube to another portion of the wall of the tube. The heavy particle recovery device recovers from the sample, heavy particles falling down. The airflow separator recovers emission gas, intermediate and light particles from an upper portion of the first column.
