    摘要： Provided is a use method of a gravity double-tube microwave-assisted grinding device capable of controlling ore thickness. The method comprises the following steps: step 1, estimating a metal mineral content of ores; step 2, calculating a penetration depth of the ores, step 3, determining a feeding size; step 4, determining a material thickness; step 5, determining a discharging speed Vp0; step 6, determining whether the gravity double-tube microwave-assisted grinding device capable of controlling ore thickness adopts a single-tube structure or a double-tube structure; and step 7, conveying the ores, performing heating, optimizing material parameters of the ores, and optimizing microwave parameters. By determining the feeding size of the ores and the material thickness, whether the gravity double-tube microwave-assisted grinding device capable of controlling ore thickness adopts the single-tube structure or the double-tube structure is determined, and the assisted grinding efficiency of a microwave equipment on the ores is improved.

    摘要： A system for refining mixed material streams, includes a receptacle for receiving an input stream; a mill grinding the input stream to reduce particle size and output a milled stream; a first filter having first filtration holes which filter the milled stream to remove a first portion having particle sizes larger than the first filtration holes and to output as a sifted stream a second portion having particle sizes smaller than the first filtration holes; a second filter having second filtration holes which are smaller than the first filtration holes, the second filtration holes filtering the sifted stream to output a filtered stream; and a density separator receiving the filtered stream and receiving a liquid. The filtered stream combined with the liquid forms a mixture, and the density separator separates the mixture into at least a first output and a second output having a greater density than the first output.
