Abstract
The invention discloses a material grading method. The material grading method includes steps of feeding mixed materials to be graded into an inner cavity of a grading barrel with a central axis transversely arranged; driving the grading barrel to rotate around the central axis, applying magnetic field to the inner cavity of the grading barrel around the circumference of the grading barrel so as to enable the graded materials from the mixed materials to be attached to the wall of the grading barrel and rotate upwards along with the wall of the grading barrel to leave away the mixed materials. By means of a discharge device, the graded materials can be separated from the wall of the grading barrel and fall into a collector and can leave away the grading barrel via a first outlet.
