Meanwhile, the grinding rate of the rod mill was higher than the ball mill [22]. The equivalent granule size declined while its specific surface area increased gradually with grinding time [23]. The grinding kinetics of quartz and chlorite followed the firstorder breakage behavior in wet ball milling [24].

The ball mill is typically used for grinding materials such as ores, chemicals, or ceramic raw materials, while the air classifier separates the ground material based on particle size. This process is commonly used in industries such as mining, ceramics, and chemicals to produce materials with specific particle sizes and properties.
