electrostatic separation equipment
φ 320*1500/2 double roll sorting machine suitable for conductor mineral and non-conductive mineral sorting to obtain high-grade conductive mineral concentrate and non-conductive mineral concentrate: such as rutile ore and zircon. It can used together with single-disc machine, double-disc machine, magnetic, electromagnetic machine, etc., this machine have 0~45000 volts high voltage generator, can also be used for high-phosphate and refractory gold red ore sorting.
Machine features:
basis of the original two-roll drum machine, improve the irrational part to improve separation efficiency, the originalhigh voltage generator from 22,000 to 45,000-volt, can be adapted to a variety of mineral separation.
Sorting principle:
High-voltage separator is the use of the material differences, in the complex combination power of corona field and electrostatic field, under the force of electricity and mechanical, to achieve the sorting of materials. When materials are took to high voltage electric field where is combined effect by the corona electrode (wire) and polarization (electrode tube) through placed with a rotation of the drums tube,the material are received the combined action of Coulomb force, centrifugal force, gravity. Due to the different of materials' electrical conductivity and stress state, so the materials have different whereabouts track, so as to achieve the purpose of sorting.
Stress state(take gold red and zircon for example)
Under the action of high pressure corona electric field, conductor (red gold) and non-conductors (zircon) of the force performance are the conductor and non-conductors both get a lot of positive charge in this electric field. But the conductor material of good conductivity, the charge adsorbed on its surface can free move, once the charge contact with the grounding drum tube, the charge on the surface of grounding drum tube will be passed away by the drums at once, after the charge were transferred away,the drum lose its adsorption effect, under the centrifugal force and gravity the mineral rotate along drums down to the side of the corona electrode, non-conductive material as electrical conductivity is poor or non-conductive surface adsorption charge can not or can not be quickly passed away, due to the opposite attraction, so its and ground drums attract each other, this attraction (Coulomb force) is greater than the centrifugal force and gravity force, so the material sucked in tight to the rear drums until it is brush down by brush, the conductivity of the material in the middle of them or the charge to rub in the rotation when he passed away of material fall in the middle. The role of static electric field (electrode tubes have) is to enhance the attractiveness of the conductor which were left off, expand the excursion of the conductor track, as for the charge of non-conductor that were not passed away is increased repulsion (same-sex repulsion), so make them tight absorption in the cylinder surface.
Product application scope:
Apply to conductors mineral and non-conductive mineral separation to obtain high-grade conductive mineral concentrate and non-conductive mineral concentrate: such as rutile ore and zircon. It can used together with single-disc machine, double-disc machine, magnetic, electromagnetic machine, etc., this machine have 0~45000 volts high voltage generator, can also be used for high-phosphate and refractory gold red ore sorting.
