3. Important Usage Notes
When replacing the ball mill entirely with new Atomfair ceramic balls for glaze grinding, it is recommended to follow these steps:
First, add water to the ball mill and run it idly for 2 hours;
Pour out the clear water, then put in the glaze for ball milling operation.
Function: Effectively eliminate the impact of impurities inside the ball mill and minor unevenness on the surface of ceramic balls on glaze purity, ensuring grinding effect.
