Application: used in wet processing (-1.2mm,i.e. -200 mesh of 30%~100%) red ore (hematite and limonite,siderite,etc.),manganese ore,ilmenite,chromite,tungsten ore and other kinds of weakly magnetic minerals and non-metallic minerals,such as quartz,feldspar,nepheline ore,kaolin for removing impurity iron and purification.
Chinese Patent and Innovation Technologies:
Experts’ conclusion in 2011: These technologies are initial at home and have reached the international advanced levels.
1.The wholly-sealed exciting coil is dust-proof, moisture-proof and heat-resisting to guarantee the equipment’s normal operation in harsh environment.There’re cooling oil passages between the single-layer winding coils,which enlarges the heat-transfer area and achieves the rapid heat exchange to keep the temperature raise range within 30?.Then as per small differences in the magnetic field of hot & cold states,the magnetic energy efficiency would be high and the excitation power can be reduced by 20% to achieve the same magnetic intensity.So one set can save the electricity 45,000 KWh one year. Please see the graph I-coil structure.
- The cooling system with wholly-sealed and outer loop structure (oil cooling coils) is rain-proof, dust-proof and anticorrosive to guarantee the equipment’s normal operation in harsh environment.Cool the oil with the intelligently controlled wind condenser to keep the constant temperature of coils, which guarantees less than 2% magnetic field fluctuation and better achieves beneficiation indicators.Achieve the rapid circulation and heat exchange by using a large flow disc transformer oil pump. Please see the graph II-cooling system diagram.
