Lately learned in the Provincial Development and Reform Commission, the Provincial Development and Reform Commission study, agreed in principle to a different Suichuan Qunxin Magnetic Materials Co., Ltd. 3000 tons / year NdFeB scrap utilization, annual creation of 1500 tons NdFeB magnets materials construction project energy assessment report.

It's understood the primary construction contents and-consuming equipment: Primary construction content for that new production plant, that old equipment materials warehouse, boiler room, sewage treatment station, energy center, finished items, recycleables warehouse, office and factory streets, drainage, electricity along with other infrastructure facilities engineering. Following the project may be the formation of annual usage of 3000 tons NdFeB scrap 1500 tons NdFeB magnets materials production scale. Project primary energy-consuming equipment just as much hydrogen station NdFeB damaged device, continuous sintering, vacuum sintering furnace, vacuum furnace with rejection, rectifier cabinet, arcing cabinet, cell, etc.

Project primary production processes and processes: Project primary production process: 1, praseodymium neodymium oxide extraction production process: NdFeB scrap, roasted, ball milling, acidity, extraction and precipitation, drying out and burning 2 , Pr-Nd alloy production process: praseodymium neodymium oxide, electrolysis, polished 3, neodymium magnet shed material production process: electrolysis of rare earth metals (metallic iron boron), melting, crushing, pressing, sintering, machining slice magnetization. Major energy-consuming processes are pressure filtration processes, roasted process, the electrolysis process, raging process, smelting processes, NdFeB hydrogen damaged step sintering process, the cutting process, rejection gang of methods.

Project primary energy consumption: The primary types of one's consumption for electricity, bituminous coal and freshwater, the annual energy use of 7516.6 (equivalent value) a lot of standard coal, the annual energy use of 7516.6 (equivalent value) a lot of standard coal. Included in this, the annual use of electricity 20,140,800 kwh, equal to 6283.93 a lot of standard coal annual use of bituminous coal 1719.16 tons, equal to 1228 a lot of standard coal annual use of 54,480 a lot of freshwater, equal to 4.67 a lot of standard coal.
