Device for crushing ore through continuous discharge and method for crushing ore by using the same

Abstract

The invention provides a device for crushing ore through continuous discharge and a method for crushing ore by using the same. A high-voltage discharge electrode partially stretches into a deionized water container, an insulating bush is arranged between the high-voltage discharge electrode and the deionized water container, the deionized water container contains deionized water, a low-voltage discharge electrode is fixedly arranged in the middle of the deionized water container, the low-voltage discharge electrode is provided with a holding chamber, the bottom surface of the holding chamber is provided with screen holes, the stretching portion of the high-voltage discharge electrode is aligned to the holding chamber on the low-voltage discharge electrode, and the upper end of the high-voltage discharge electrode is connected with the rotating shaft of a motor. The device for crushing ore through continuous discharge and the method for crushing ore by using the same have the beneficial effects that the crushing of ore through continuous discharge can be realized, the problem that discharge dead zones exist during electrode discharge is overcome, the electric crushing efficiency of ore is improved and the subsequent treatment difficulty of ore is reduced.

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...

AI Technical Summary

Problems solved by technology

The disadvantages of this method are: firstly, the operation cannot be continuous, and secondly, the crushed particle size is not easy to control, the crushed ore needs to be sieved, and the ore that fails to reach the crushed particle size needs to be returned to the discharge chamber for re-crushing
