Wet milling, a core aspect of the wet grinding process, involves breaking down materials in a liquid medium. The wet ball milling process, a popular choice in many sectors, employs a ball mill to achieve a fine grind. This method is particularly effective for materials that are too hard for standard milling. Steps in Wet Ball Milling Process
An edge inspection tool should examine the wafer for particles, scratches, chips and cracks on the entire bevel region. Polishing- or handling-related chips or cracks can result in a high stress point on the pristine crystalline structure. When the wafer undergoes thermal processes, these defects can create significant stress buildup.

The components of a ball mill, including the drum, grinding media, liners, and drive system ...
Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
