Abstract

La aplicación proporciona un preseparador en seco, que comprende una vía de aire de soplado posterior y un mecanismo de rodillos magnéticos excéntricos, en el que el mecanismo de rodillos magnéticos excéntricos está parcialmente dispuesto en la vía de aire de soplado posterior y se utiliza para transportar materiales y proporcionar un campo magnético giratorio excéntrico; una zona de alimentación está dispuesta por encima del mecanismo de rodillos magnéticos excéntricos; y una zona de relaves, una zona de relaves intermedios y una zona de concentrado están dispuestas por debajo del mecanismo de rodillos magnéticos excéntricos. En la aplicación, los materiales de la zona de alimentación se transportan a la vía de aire de soplado posterior para que rueden, de modo que los materiales magnéticos fuertes se encuentren en la capa más interna, los materiales magnéticos débiles en la capa intermedia y los materiales no magnéticos en la capa más externa; bajo la acción del aire inverso en la vía de aire de soplado posterior, los materiales no magnéticos en polvo fino de la capa más externa abandonan una superficie del mecanismo de rodillo magnético excéntrico para ser arrastrados por el aire o caer en la zona de relaves; y los minerales magnéticos débiles caen a la zona de relaves intermedios con la rotación del rodillo magnético y la atenuación del campo magnético, y los concentrados caen a la zona de concentrados con la rotación del rodillo magnético y la atenuación del campo magnético, de modo que se realiza la separación graduada, eficiente y fina de los materiales ultrafinos.The application provides a dry preseparator, comprising a back blow air path and an eccentric magnetic roller mechanism, wherein the eccentric magnetic roller mechanism is partially arranged in the back blow air path and is used to transport materials and provide an eccentric rotating magnetic field; a feeding zone is arranged above the eccentric magnetic roller mechanism; and a tailings zone, an intermediate tailings zone and a concentrate zone are arranged below the eccentric magnetic roller mechanism. In the application, the materials in the feeding zone are transported to the rear blowing air path for rolling, so that the strong magnetic materials are in the innermost layer, the weak magnetic materials in the middle layer, and the non-magnetic materials in the outermost layer; under the action of reverse air in the after blowing air path, the fine powder non-magnetic materials of the outermost layer leave a surface of the eccentric magnetic roller mechanism to be carried away by the air or fall into the tailings area; and the weak magnetic ores fall to the intermediate tailings zone with the rotation of the magnetic roller and the attenuation of the magnetic field, and the concentrates fall to the concentrate zone with the rotation of the magnetic roller and the attenuation of the magnetic field, so that Graduated, efficient and fine separation of ultrafine materials is carried out.
