In the modelling of the ball mills, perfect mixing approach proposed by Lynch [20] was utilized. Within this approach, a whole ball mill or its one of the sections are being considered as perfectly stirred tank and the process is described mainly by breakage within the mill and the transport through the mill.
Ball Mills: These cylindrical mills use steel balls or rods as grinding media and are often employed in the mining industry for grinding ores into fine powders. Hammer Mills: Commonly used in food processing and agricultural industries, hammer mills use hammers attached to a spinning rotor to crush and grind materials into smaller particles.
The grinding action in a ball mill is achieved through two primary fragmentation mechanisms: attrition and the impact. Impaction happens when the grinding media (balls or hard pebbles) bump into each other and with the material being ground. This leads to the fragmentation of the substance into pieces of smaller size.
