Re-election equipment in the tailings recovery

 
In  the weak magnetic iron ore concentrator of our country, there is   no special equipment in the tailings recovery fields, in recent years a number of highly efficient, advanced and mature processing equipment as a Tailings equipment are adopted .for example, Slon high gradient magnetic separator as a weakly magnetic iron ore tailings and recycling equipment to be applied in on plant iron ore recovery of hematite, limonite and Panzhihua Iron and total tailings recovery of ilmenite, etc., and finally obtained significant economic benefits.
Re-election equipments in the tailings recovery are receive attention in recent years, and put into production applications.the Prominent equipments are spiral chute, shaking, continuous centrifugal concentrator and so on. Among them, Beijing Mining Research Institute, developed  spiral chute since the 1970s, and then the successful development of diameter were 400 mm, 600 mm, 900  mm, 200 mm separately, L series of spiral chute. On this basis, the development of the success of the BL in 1999 - 1500-A spiral drop slot for the fine gravity separation and desliming has been developed to the 3rd generation of BL -1500 - A3 type, its improved A2, A3, type spiral chute concentrator tailings and metallurgical slag recovery re-election project has also been widely used. The Ganzhou Circle Magnetic Separation Equipment Co., Ltd. to develop a continuous centrifuge for success SLon. Water jet beam SLon continuous centrifuge applications on centrifugal force compaction cleaning and cutting principle of the large density of the granular layer, continuous centrifugal force field to the discharge of the centrifugal separation process, with good separation efficiency, processing power, adaptability and energy saving and environmental protection features.10 SLon - 1600 mm x900 mm continuous centrifuge used in the selected row the tailings SLon magnetic roughing Hainan Iron and Steel Company, a centrifuge recovery process, nearly three months of the Slon continuous centrifuge industrial test production targetsThe feed grade of 50.52%. Iron concentrate grade of 56.56%, the operating rate was 61.59%, stand-alone processing capacity 2.0 to 3.0 Uh,. Played an important role in the ultimate high-grade iron concentrate product. 
  This machine was the first generation of disc permanent magnet recycling machines Chinese successfully developed  .  Install the HS - cafe 1600 mm x8 permanent magnet with a receiver in the tailings chute, less than half of the magnetic disk disk immersed in the tailings slurry, boot the disc rotation direction and the flow of slurry phase reverse operation, adjust the slurry body velocity, flow rate and disc speed to achieve the best match. Magnetic minerals in the disc between the flow through the tailings slurry is sucked on the disc with the disc rotation with the slurry surface by the rinse water, rinse under magnetic gangue mineral surface attachment, scraping plate blew into the magnetic product chute, water rushed into the crude concentrate mineral collector chute sent to the next process. Gangue mineral tailings which flow with the tailings slurry  are discharged from the discharge gate to complete the sorting process.
