| Zusammenfassung: | The airflow crushing and grading process of producing tungsten carbide (WC) powder includes coarse crushing, airflow crushing, airflow grading and material collection. The present invention designs the technological parameters of airflow crushing and airflow grading based on the features of WC material, including high hardness, high density, high melting point, etc. and makes it possible to produce superfine WC powder of average granulation smaller than 0.2 micron and low impurity content, in high production efficiency and high yield and low cost. |
