Description

Technical Field

[0001] The utility model relates to the technical field of silicon nitride grinding, in particular to a silicon nitride ball mill. Background Art

[0002] The ball mill is a key equipment for crushing materials after they are broken. This type of grinding mill has a certain number of steel balls loaded into its cylinder as grinding media.

[0003] During the production process of silicon nitride, if its surface needs to be smooth according to the needs of use, a ball mill needs to be used to grind the surface of the silicon nitride. When using existing ball mills, the silicon nitride plate needs to be fixed in the ball mill for ball milling. When using this method, since the silicon nitride plate is fixed, its clamping part cannot be ball milled. Therefore, in actual use, the untreated part needs to be ground separately, which affects the ball milling efficiency of the silicon nitride plate. Utility Model Content
