Method and apparatus for intensified disintegration for dry materials

Abstract

A method and device for enhanced crushing of dry materials. The method includes setting a high-frequency electric pulse generator and a conductive device on the shell of a crusher or pulverizer, and transmits the electric pulse action of the generator to the material to be crushed through the shell; the device includes A high-frequency electric pulse generator provided on the shell of the crusher or pulverizer and a conductive device that maintains an uninterrupted electrical connection between the generator and the shell of the crusher or pulverizer; wherein the electric pulse of the high-frequency electric pulse generator The frequency is 150-3000 Hz, the voltage is 12 volts, and the converter power is 100-500 watts.

Description

technical field [0001] The invention relates to an intensified pulverization method and device for crushing and pulverizing inorganic dry material-dielectric medium. technical background [0002] With the increasing scale of mining lean ore and the increasing development of mineral processing, the energy consumption of crushing and crushing continues to increase. Currently, more than 100 billion tons of minerals are processed globally each year. In most ore processing enterprises, the basic investment, operation and energy consumption of crushing and crushing these ores account for more than half of the enterprise's economic balance sheet. Therefore, it is becoming more and more urgent to reduce the cost of the crushing and crushing process. [0003] The task of reducing the energy consumption of various dielectric processes such as shredding and comminuting is also directly related to the problem of environmental pollution, since the vast majority of the world still uses ...

Problems solved by technology

[0004] As we all know, the existing enhanced crushing technology includes the use of water decomposition method or the method of using surface active substances to strengthen the crushing, but the cost of dehydration and drying of the crushed material required by this method is too high

[0005] Therefore, for the dried finished product, the finished product is generally directly obtained by crushing the dry raw material, which requires the traditional physical-chemical method or the new method of destroying the hard object similar to the physical-chemical method to reduce the firmness of the hard material, but they Both in terms of technology and engineering form, there are great limitations
