Is useful the model of [otnosits] to [dl] technique of [izvlecheni] of particles from the dispersal systems (suspensions, colloidal solutions, suspensions) it can be used at the point of the extraction of the minerals of [dl] of [izvlecheni] of free metals (gold, platinum and of others), oxides of the majority of metals, protein substances and so forth of [dl] of [razdeleni] charge of the [zhennykh] particles, [dl] of the purification of water. Task : the guarantee of a possibility of [izvlecheni] of the small and thin nonmagnetic fractions of nonferrous, rare and precious metals from the mixture of dispersed nonmagnetic materials. Essence : separator is the containing loading unit, the means of [privedeni] beside the flow of pulp, the housing containing channels [dl] of the separate conclusion of flows the division of the [emykh] components, the means of three-dimensional [razdeleni] of the flow of pulp down the flows the division of the [emykh] components, executed in the form of magnetic system, is which it contains the pulse generator of current and solenoid, [otlichaets] fact that the generator is executed with the possibility of [generirovani] of powerful current pulses, with the speed of [narastani] of current before the pulse dI (t) /dt is not less than 108 A/s with the asymmetric before the time form of current pulses, with the duration of their leading edge of smaller than the rear, moreover the design parameters of the solenoid of [prin] you from [uslovi] of [obespecheni] of force of [vzaimodeystvi] magnetic field wire by [shchimi] particles (F), in accordance with the expression Of f?σ×r4×H (t) of ×dH(t) /dt, where σ - the specific conductivity of particle; R - linear dimension of particle; H (t) for example [zhennost] magnetic field is not less than 106 A/m, with the gradient (grad H) not less than 108 [A]/[m]2, furthermore, value for example [zhennosti] magnetic field before the channel of [dl] of the conclusion of the flow of that containing useful component is equal to 0; moreover solenoid is placed out of the cavity of the housing of separator, on its external wall. 2 illustrations. |
