2, not water, economize on electricity.

3, saving of labor, laborsaving is pollution-free.

Below the utility model is described further:

Basic principle: utilize the graphite good electrical conductivity, with the insulating properties of ores such as quartz, utilize charge characteristic, the same sex is repelled each other, and there is a natural attraction between the sexes reaches sorting purposes.

The course of work: mineral aggregate is behind ion sieve, make each ore particle all have negative electrical charge, reach individual layer cloth purpose (same sex is repelled each other), mineral aggregate is had high-voltage positive electrode and inhales mutually and be evenly distributed on the high-pressure metal conveyer belt when falling, dielectric object in the breeze, the upper side band negative electrical charge can not be transmitted on the following high-voltage positive electrode, negative positive situation down in the formation, the mineral medium is inhaled securely on the metal guide plate like this, and conductive materials forms the positive charge peak dot of an enrichment on guide plate, anodal guide plate is a mutual expelling force to the conductor material.When mineral are sent to when scolding utmost point guide plate, the conductor powder is under the repulsion effect of positive plate, to opposite electrode movement, by the side of sucting, motion forwards under the effect of strong magnetic force, accumulator tank forwardly, have positive charge, the conductor ore particle is absorbed, the mineral of medium travel forward, brush by the metal tape below is brushed, and reaches the graphite sorting purposes.In order to improve the rate of recovery, in the back of guide plate, the top of conveyer belt adds an emission of ions head, utilizes the aerial snowslide phenomenon of ion, utilize powerful ion remaining graphite again sorting go out, to reach the purpose that improves the rate of recovery.
