【Abstract】 Aiming at the magnetic field strength of the magnetic field is greatly attenuated,the depth of the magnetic field is small,the magnetic field is uneven and the entrainment is serious of cylinder magnetic separator and the belt surface magnetic field strength attenuation is large,belt life is short and replacement cost is high of belt magnetic separator, WFS reciprocating magnetic separator is developed.The sorting principle and technical characteristics of WFS reciprocating magnetic separator are introduced.WFS1216 reciprocating magnetic separator is used in industrial application in some quartz sand plant in Guangdong.Under the condition that the Fe₂O₃ content of the ore feed is 0.065%,the quartz fine sand obtained after one sorting contains 0.042% Fe₂O₃.When the refined sand yield is 97.12%,the iron removal rate of the operation can reach 37.24%,which effectively removes mechanical iron and strong magnetic minerals,avoids the medium jamming of the strong magnetic separator in the subsequent operation process,the equipment runs smoothly,and the failure rate is low.The development of the WFS reciprocating magnetic separator has added a new type of equipment to the field of strong magnetic mineral pre-selection.It can also be used for the separation of weak magnetic minerals under the background of high magnetic induction intensity,and has broad market application prospects.更多还原
