Abstract
It is known that the effective work of drum-type magnetic separators is determined only by those forces which act in the radial direction, since strongly keeping magnetic mix on the drum surface with their transportation to the output of magnetic product. The disadvantage of this magnet system is the insufficient value of the magnetic force component of field which acts on the magnetic particles in the direction of their precipitation on the drum surface. This system is used for slight magnet particles precipitation. Mathematical simulation and calculation of magnetic field with the antiradial magnetization shows an increase in the precipitant magnetic forces (by normal component of total magnetic force) by 10%-30% in comparison with the analogous in the sizes, known as magnetic system. Non-uniformity of magnetic field of induction on the surface is less to 1.3 and radial magnetic force to 1.7.
