Magnetic Separator Broadly Used in Gangue Dealing

The magnetic separator is used in the re-use of the powder particles to remove iron powder and others. The magnetic separator is widely used in the factories for recycling, timber industry, mining, ceramic, chemical, food, etc. It is applicable for the wet magnetic separation of magnetite, pyrrhotite, roasting ore, ilmenite and other materials whose particle size is below 3mm. The magnetic separator also can be used for the iron removal operations of coal, non-metallic minerals, building materials and other materials which is the most widely used and most versatile-species one in the industry.
In 2005, the concentrator factories adopt high frequency vibrating screen and composite tailings selection technology and flashing magnetic separator. As a result, the ore tailings final grade was reduced by an average of 2.44%. Figures showed that we annually may elect from the tailings 31,190,000 tons of iron ore concentrate, with the concentrate grade 67. 13%, which can achieve annual benefit of RMB 54 million. Production practice of iron ore tailings re-election indicates that ore concentrator factories discharge 2.28 million tons of tailings a year. The tailings processed by the JHC rectangle ring type magnetic separator, and we gained elected rough ore concentrate, and then the concentrator is pumped to a separate built concentrate plant. It will go through weak magnetic separation, grinding-classification, magnetic dewatering tank and double drum weak magnetic separation process, and finally we get the final ore concentrate. To a service-oriented brand integrity,As the professional manufacturer of complete sets of mining machinery, like flotation cells, Henan Hongxing is always doing the best in products and service.cement making machine:http://www.hxjq-crusher.com/
At present, the tailings discharged are about 400million tons to 500 million tons in China, accounting for one third of industrial waste. Among of them, the metal tailing takes for one forth, metallurgy and boiler slag take for 26%, chemical slag takes for 4%, fly ash and gangue take for 35%. The metal recycling process will use magnetic separator and other matched ore dressing equipment. The tailing slag recycling process adopts gravity separation and magnetic separation process, so that recycle iron ore from tailings. As for different metals in the tailings, we will use spiral chute, shaking table and strong magnetic separators with different specifications. For the time being, disk magnetic separator in weak magnetic field, big drum cylindrical magnetic separator in medium magnetic field and high gradient magnetic separator all have been applied to tailing recycling production.
In contrast to a magnetic roller with electromagnet, permanent magnets are made up of magnetite, that doesn’t require any electric current so as to behave as a magnet. Permanent magnet also generates its own magnetic effect that circulates around the magnet. The magnetic field of a permanent magnet can easily be found by spreading iron ores around it. These magnets quickly submit along the field lines of a magnet.
