Abstract

A METHOD FOR CRUSHING HARD MATERIALS, for example, brittle metals, with the help of electric shock, arising from impulse electrical discharges in a liquid closed in a vessel, “jepea, which is permeable to the material to be milled, characterized in that electrode closures • when crushing conductive materials, a non-conductive GOK material is simultaneously introduced into the vessel along with the material being ground, in an amount greater than the amount of the finished material.

WITH

There is a known method of crushing solid materials, for example, brittle metals, with the aid of electrohydropneumatic shocks arising from pulsed electrical discharges of a liquid enclosed in a vessel through which the material to be ground is passed.

The purpose of the invention is to eliminate the possibility of short-circuiting the electrodes i p when crushing conductive materials.

This is achieved by the fact that according to the prepacking method, a material that does not conduct an electric current is simultaneously introduced into the vessel together with the material to be ground. The amount of input material must exceed the amount of the main material being ground.

The figure schematically shows a device for crushing solid matter. riyals.

A lumpy material 2 (fragile megaples, carbide, alloy, etc.) that is preliminarily mixed with pieces of viscous material with large internal friction and non conductive material 3 (diabase, capron, etc.) Is continuously fed into vessel 1. e), taken in an amount exceeding (in volume) the amount of ground comminuted material.

In the process of electrohydraulic crushing, the crushed material together with the liquid is continuously removed from the device through the perforated bottom 4. The finished material is directed to the separation of components, using conventional means. Separation of components can also be carried out in the device itself during the fragmentation process.
