       锰矿磁选机的工作原理: 将小于5毫米的原矿送入上料斗,经过振动电机振动布料,出料口的大小可通过手轮来精确调整给料量的大小。磁辊通过调速电机拖动,转速的快慢通过调速表来进行调节,可控制磁选机的产量和精矿品位。矿粒经输送带被送入上磁辊分选,由于锰矿粒有磁性,立即被强磁场吸附在磁辊上,而脉石矿物(以石英为主,其次为白云石,方解石,绢云母,长石,粘土类矿物等)由于没有磁性,磁辊的强磁对它不产生吸力,随着磁辊的转动,锰矿粒一直被吸在磁辊上,而脉石粒在磁辊转到前端位置时被抛出掉在隔矿板的前面(通过改变隔矿板角度的大小可调整精矿的品位),锰矿粒继续被磁辊带到脱磁区时自动掉入一选集矿斗收集为精矿成品。由于上磁辊掉下的脉石中还夹带有一些磁性更弱的锰矿粒,它们将进入下磁辊继续进行磁选,磁选后的成品锰矿粒进入二选集矿斗收集为成品,被抛出的脉石经尾矿口排出,至此磁选工序结束。由于锰原矿中的脉石被抛弃,所以使锰矿的品位得到提高。整台设备的用电量仅为1KW,磁选投入成本是相当低的。

The separator works manganese : less than 5 mm of the ore fed to the hopper via the vibration motor vibration of the cloth , the size of the discharge port to the feeding amount can be precisely adjusted by the size of the hand wheel . By dragging the magnetic roller speed motor , the speed of the speed table to be adjusted by the governor , to control production and concentrate grade magnetic separator . Is fed by mineral particles on the magnetic roller conveyor sorting , because manganese magnetic grains , immediately attracted a strong magnetic field on the magnetic roller , while the gangue minerals ( quartz , followed by dolomite , calcite, sericite, feldspar, clay minerals , etc. ) in the absence of a magnetic , magnetic magnetic roller it does not produce suction, with the rotation of the magnetic roller , manganese grain has been sucked on the magnetic roller , while the gangue grains in the magnetic roller to the front automatically fall into an anthology collection of fine ore bucket position when the mine was thrown out at the plate across the front ( mine plates separated by changing the size of the angle adjustable concentrate grade ) , manganese grain sector continues to be taken off the magnetic roller mineral products. Since the fall of the magnetic roller entrained gangue also some weaker manganese magnetic grains , they will continue into the next magnetic roll magnetic separation, magnetic separation after the grain into two anthology of refined manganese ore bucket collection was finished , was thrown the gangue by tailings discharge port, thus ending magnetic processes. Because manganese ore gangue been abandoned, so make the grade manganese improved . The entire device power consumption is only 1KW, magnetic input costs are quite low.
