Description

Technical Field

[0001] This utility model relates to the field of silicon carbide grinding technology, and in particular to a grinding device for silicon carbide nanopowder. Background Technology

[0002] Existing silicon carbide nanopowder grinding devices often suffer from insufficient grinding, making it difficult to guarantee grinding quality. Furthermore, inconvenient material feeding and discharging negatively impacts operational efficiency. A Chinese patent, CN202020323993.7, discloses a novel grinding device for silicon carbide production, featuring a grinding drum and a top grinding wheel. During operation, the rotation of a bottom adjusting screw moves a rotating clamping jaw inwards or outwards, clamping or releasing the bottom grinding wheel. The center of gravity of the bottom grinding wheel must be aligned with the feed pipe. Rotating the top adjusting knob then rotates the connecting screw, simultaneously moving the screwed positioning block inwards or outwards, thereby clamping or releasing the top grinding wheel using the fixing jaws. This effectively solves the problems of existing silicon carbide grinding equipment where grinding wheel wear affects silicon carbide powder purity and grinding wheel replacement is inconvenient. However, this device still suffers from insufficient grinding, affecting grinding quality; inconvenient material feeding and discharging; high operational difficulty; and low overall efficiency.
