Effect of Rod Arrangement in Matrix on High Gradient Magnetic Separation Performance

Abstract:

The effect of rod arrangement in a rod matrix on high gradient magnetic separation (HGMS) performance has been comparatively investigated through a cyclic pilot-scale centrifugal HGMS separator, with contiguously and orthogonally arranged rod matrixes respectively. The results of investigation indicate that the arrangement of rod elements in the matrix has a distinct effect on the HGMS performance, for relatively low magnetic inductions; beyond the threshold magnetic induction, the magnetic induction dominates that of the arrangement and the importance of the arrangement is significantly weakened even vanished. It was thus concluded that the combinatorial optimization for magnetic elements in the matrix improves the collision efficiency of particles with matrix, and gives a superior performance in a HGMS separator, at a lower energizing consumption.
