Matrices and capacity of a high-gradient separator
High-gradient magnetic separation (HGMS) and high-field magnetic separation (HFMS)

With regard to matrix optimization and adaptation, in an SMHG separator, it has been shown ( [J 3 220] , § 2.2), that the ratio λ (D/d) can reach a value of 10 without affecting the efficiency of the processing operation.

Trying to optimize the ratio λ of magnetic attraction force to fluid drag force generally tends to equate the capture phenomenon with a filtration mechanism. If the ratio λ < 10, this filtration mechanism is dominant and leads to the formation of a deposit of material on the matrix, which increases resistance to the fluid. The phenomenon of mechanical filtration must be avoided as far as possible in industrial operations, and for this reason...
