MAGNETIC FORCE SELECTION DEVICE, METHOD FOR USING MAGNETIC FORCE SELECTION DEVICE AND CONTAMINANT DRY PROCESSING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a magnetic force selection device which is excellent in classification performance and convenience compared to a conventional magnetic force selection device.;SOLUTION: A magnetic force selection device 1 that selects a selected object 201 formed by mixing a particulate contaminant and strong magnetic powder and/or paramagnetic powder includes a rotary drum type magnetic separator 10 having a magnet 18 arranged therein; and a selection device 31 which is installed on a selected object discharge port 25 of the magnetic separator 10 and sorts a selected object 202 into a particle size of N or more (N is an integer of 2 or more), where the magnetic separator 10 includes a position variable mechanism which can change a position of the magnet 18 to a rotary drum 11, and the selection device 31 includes a particle size variable mechanism which can change the sorted particle size.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
