Davis Tube / Davis Tube Tester / Davis Magnetic Tube Tester / Laboratory Magnetic Separator


Davis magnetic tube or Davis magnetic tester is a laboratory machine designed to separate a small sample of pulverized magnetic iron ore into magnetic and non-magnetic fractions. Davis separation tube is positioned between poles of a powerful electromagnet at an angle of 45° (adjustable) that is agitated back and forth and rotated by a motorized system. Magnetic particles are collected inside the tube in the zone of intense magnetism and all non-magnetic minerals are washed out.


XCGS Davis magnetic tube or Davis magnetic tester can be used in laboratories of mine, metallurgy and geology.
