One Of The High Level Materials Silicon Metal Powder

A silicon metal powder ball mill, including a base plate, wherein the top surface of the base plate is fixed with two support rods, and a ball mill body is rotatably connected to the two support rods. The ball mill body is equipped with a feeding port, a discharge pipe is rotatably connected to the right side of the ball mill body, and a feeding pipe is rotatably connected to the left side of the ball mill body. An operation box is fixed on the top surface of the base plate, which has a conveying component. The conveying component includes a partition, which is fixed between the top wall and the bottom wall of the operation box. A supporting plate is fixed to the left side of the partition. The metal silicon powder ball mill is equipped with a conveying component. The material crushed by the ball mill body enters the right side of the operation box. The material that meets the crushing quality falls into the inner bottom wall of the right side of the operation box through a filter screen, while unqualified materials can be transported back to the ball mill body for secondary crushing by a conveying pump, improving product quality and achieving better use effects.

1.A method for preparing spherical silicon metal powder using a plasma flame gun, which pertains to the field of industrial silicon production, includes: Firstly, connecting the first gas source and the metallic silicon powder raw material to the intake of the plasma flame gun via a gas pipe; then, supplying power to the anode and cathode of the plasma flame gun; finally, once the plasma flame gun ejects plasma, collecting the spherical metallic silicon powder sprayed from the gas outlet nozzle. In this invention, an arc is generated between the nozzle (anode) of the plasma flame gun and the electrode (cathode), instantly turning air or inert gas in the first chamber into a plasma state, which can quickly melt the metallic silicon powder raw material into spherical metallic silicon powder; at this time, the air pressure inside the first chamber increases, driving the plasma to eject from the first chamber in the form of a plasma beam through the nozzle, with a temperature as high as approximately 9000°C, capable of quickly melting the metallic silicon powder raw material into spherical metallic silicon powder.
