FIELD : mining.SUBSTANCE : present invention relates to concentration of minerals and may be used in the mining industry and other industries of the national economy. Invention allows for increasing the magnetic field strength and separation quality. The magnetic system consists of a set of polar blocks with alternating polarity, and interpolar blocks installed on a magnetically conductive yoke and made of strontium ferrite. The polar and interpolar blocks are mated with their like poles. The polar blocks are made of different hard magnetic materials, most of them being made of strontium ferrite, white the plate facing the internal drum surface is made of a rare earth material, the polar block length ratio ranging from 10 : 1 to 1 : 1, and their area ratio ranging from 1 : 1 to 1 : 0.5.EFFECT : increased magnetic field strength and separation quality.1 dwg
