[0002] A wheel mill is a material crushing or mixing device with a millstone and a millstone as the main working parts. The wheel mill is divided into a rotary wheel mill and a disc rotary wheel mill according to the rotation mode of the mill wheel. In the process of producing vanadium-nitrogen alloy, a wheel mill is generally used to grind and mix materials such as vanadium compounds, carbon-containing compounds, reaction accelerators and adhesives.
