The present invention relates to a dry sorting concentration and separation method (mainly for particles smaller than 1mm) and a dry sorting concentration and separation system. The dry sorting concentration and separation method comprises: crushing the ore in a crusher and grinding it by dry grinding first, and then concentrating the material in a dry sorting concentrator under the condition of air flow and vibration generated by a second directional vibrator, wherein, the second directional vibrator is arranged at 20~60° included angle to the horizontal direction, the dry sorting concentrator creates a turbulence field to separate the material, a perforated plate is arranged at 2~20° included angle to the horizontal direction, the thickness of the material is equal to or smaller than 40mm; the system comprises a material feeding device, a friction vibrating separator, and a dry sorting concentrator, wherein, the material feeding device is arranged above the friction vibrating separator, at least two material transport chutes are arranged below the friction vibrating separator, and at least two material transport devices are arranged above the dry sorting concentrator. |
