Ball Mill an overview ScienceDirect Topics

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.

Case study Wikipedia

Research methods. In business research, four common case study approaches are distinguished. First, there is the "no theory first" type of case study design, which is closely connected to Kathleen M. Eisenhardt's methodological work. The second type of research design is about "gaps and holes", following Robert K. Yin's guidelines and making positivist assumptions.
