The morphological properties of particles pulverised in a stirred mill were studied using automated and manual detection methods in this work. Particle breaking processes such as fracture or abrasion determine the morphological surface qualities of product particles. To reduce comminution energy consumption, it is critical to promote breaking mechanisms that accomplish mineral release with the least amount of energy. Intergranular particles should have rough surfaces, whereas transgranular particles should have softer surfaces. High-speed swirled mills, according to the literature and common belief, shatter particles by attrition. In this investigation, fracture was discovered to be an important breaking mechanism alongside attrition. The mill agitator acts as an input stress level. The breaking mechanism is affected by mill agitator speed as well as the kind of mineral. At greater agitator speeds, galena fractures along grain boundaries, whereas quartz abrades throughout the grain.
