Sec-Separation Density Online Regulation Of The Three Product Heavy Medium Cyclone In Magnetic Field

Through analysis software ANSYS electromagnetic field distribution inside the cyclone simulated in laboratory studies and overflow,underflow suspension density and sorting experiments with coal,to Magnetic field under study conical cylinder heavy medium cyclone separation density of online regulation,providing a theoretical basis for the subsequent three product heavy medium cyclone separation density Sec online regulation.1?Magnetic field distribution exploratory stage:analysis based on distribution of the magnetic field results,either axial or radial turns laps,the changes have an impact on the distribution of the magnetic field strength H values,the more turns and turns,the greater the value of H,in addition to the magnetic field strength H value distribution can be obtained axial fewer turns,so that in the experiment of cyclone separation,the higher the accuracy of the density change;distribution of the magnetic field based on the above analysis,and ultimately determine the basic parameters for the axial width of the coil 75mm,the radial thickness of 150mm.2?Magnetic exploration stage:magnetic particles are subjected to a plurality of forces in the cyclone,of which the maximum is centrifugal force,The calculation of a single particle size of the centrifugal force,the centrifugal force obtained 10-7 magnitude;so long as the magnetic force in the 1?10×10-7N range,can have an impact on the magnetic particles;Calculated by magnetic,to calculate the size of a single magnetic particle suffered through several comparing the current value of exploration,and ultimately determine the current value of the size range between 3?10A.3?Experimental stage with coal:In experiments with coal sorting,through the overflow and underflow products were drifting analyzed and plotted distribution rate curve,draw the actual separation density 8 p value and potential value of the deviation Ep.Analysis shows that under the action of a magnetic field,sorting density from 1.58 X 103kg/m3 increased to 1.61×103kg/m3,so as to illustrate the existence of the magnetic field can be adjusted online sorting density,while Ep values increased from 0.075 to 0.085,Ep values increased sorting effect of variation explained,probably because there is no magnetic field distribution optimization,a new form of the density field in the form is very unstable,resulting in a serious mismatch.Therefore,the next research should focus on the major changes in the density field density field stability mechanism and the two aspects.Figure32;Table11;Reference 65.
