Experimental studies on the preparation and beneficiation of iron ores were carried out in the laboratories of Saint Petersburg Mining University jaw crusher roller crusher ball mill Laarmann Flotation Bench Test Machine laser diffractometer Mastersaizer drum magnetic separator BS 20/10 N − drum magnetic separator PBM P 25
Features Sustain and reliable magnetic field with strong magnetic force Compact structure light weight and easy to maintain Featuring with dust and rain protection wearing erosion it can run in the harsh environment Low energy consumption and reliable performance Optional magnetic
As shown in Figure minerals with ferromagnetic properties have high susceptibility at low applied field strengths and can therefore be concentrated in low intensity < T magnetic separators For low intensity drum separators Figure used in the iron ore industry the standard field for a separator with ferrite based magnets is T at a distance of 50 mm from
The weak magnetic separation process is often added before the strong magnetic separation process to separate the strong magnetic minerals in the ore in case that the strong magnetic minerals may cause the blockage of the magnetic separator After the weak magnetic separation the strong magnetic rough separation and sweep selection are carried
