Abstract
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.
