Abstract

The invention provides a device for continuously discharging ore and a method for crushing ore. The high-voltage discharge electrode part extends into the deionized water container, and an insulating sleeve is arranged between the two. The deionized water container is filled with deionized water. In addition, the low-voltage discharge electrode is fixed in the middle of the deionized water container. There is a cavity on the low-voltage discharge electrode, and a mesh hole is set on the bottom of the cavity. The high-voltage discharge electrode extends into the cavity on the low-voltage discharge electrode. Turn the shaft. The beneficial effect of the present invention is that it can realize continuous electric discharge crushing of ore, overcome the problem of discharge dead angle in electrode discharge, improve the efficiency of electric crushing of ore, and reduce the engineering difficulty of subsequent processing of ore.

Description

technical field [0001] The invention relates to a device and a method for crushing ore, which can not only realize continuous crushing of ore, obtain ore with a certain particle size, but also overcome the discharge dead angle of high and low voltage discharge electrodes. Background technique [0002] Pulse discharge ore crushing is a new crushing technology developed in the past few decades. It uses the mechanical effects of shock waves, jets or plasma channels generated by pulse discharge to damage ore. There are no flying stones and no toxic and harmful substances in the crushing process. The process of generation and discharge is easy to control. When the ore is crushed by electric discharge, there are differences in the electrical conductivity and dielectric constant of the ore particles that make up the ore, which can make the metal particles more easily exposed, improve the efficiency of ore dressing, and reduce the harmful chemicals such as sulfuric acid and hydrogen...
