The cylindrical electromagnetic plasma melting reactor with the inclined electrode is characterized in that: the upper part of the bottom of the reaction chamber is provided with a lining built by chrome-magnesium refractory bricks, and the lining inclines from the inner wall of the reactor to the center of the bottom.

the material to be crushed, namely powder or granular material, is put into the reaction chamber through a pipeline of the feeding port. First a planar layer of small particles of a conductive material in the form of a condensate is created between the surface layers of the material particles in the central part of the reaction chamber. For example, graphite powder is used which can be used to connect 3 or 6 rod-shaped electrodes. Then three controllable silicon power supplies which can be regulated are switched on, and then current is conducted to penetrate through the graphite layer to heat the graphite layer. And transferring the heat generated by the current to the material body connected with the graphite layer, and finally forming a working molten pool in the reaction chamber.

In order to remove the melt from the reaction chamber, the additional fixed rod-shaped electrode is lifted, the hole on the diversion opening is opened, and when the fluidity of the solution is enough to ensure that the solution flowing out of the diversion opening can flow freely, the additional fixed rod-shaped electrode is stopped at a slightly lifted position in the solution in the reaction chamber. If the melt flow can not freely flow out of the flow guide opening, the additional fixed rod-shaped electrode is put down to seal the central hole of the flow guide opening. The molten pool is continuously heated by the main power supply.
