Grinding kinetics of −3.0 + 1.0 mm coal in wet ball-milling were investigated using the breakage rate and primary breakage distribution functions. The deceleration effect for the wet grinding of this coal sample was due to the relatively stronger material (quartz), which had a slower breakage rate compared to the weaker material (organic matter).

Laboratory ball mills are scaled-down ball mills that use milling jars that are filled with grinding media and rotated using a jar rolling mill to reduce the particle size of the material. While they are commonly used for small size applications, options are available that can also be used for larger production opportunities. Long Roll Jar Mills

Loading the Mill: The ball mill is loaded with the material to be ground and the grinding media (balls). The material can be fed into the mill either wet or dry. Rotating the Mill: Once loaded, the cylindrical shell starts rotating around its horizontal axis. Various mechanisms, such as gears, belts, or direct drives, can facilitate this rotation.
