How to use the pollutant dry treatment system and the pollutant dry treatment system

摘要

PROBLEM TO BE SOLVED: To provide a magnetic force selector capable of selection corresponding to the concentration of a pollutant or selection corresponding to the characteristic of a selection object.SOLUTION: A magnetic force selector 1 for selecting a selection object formed by mixing a granular pollutant and ferromagnetic powder and/or paramagnetic powder includes a rotary drum 11 having a magnet 14 arranged inside, and a selector 31 installed on a selection object discharge port 25 of the rotary drum 11, for classifying the selection object into N (N is an integer of 2 or larger) or more particle diameters, in which the selector 31 includes a particle diameter changing mechanism capable of changing particle diameters for classification.SELECTED DRAWING: Figure 1
