Sustainability of coal mines: Separation of clean coal ...

As grinding time is directly proportional to the energy consumption, experiments were planned for every 15 min of increment. At a lower grinding speed of less than 200 rpm, the slurry was not homogeneous and the maximum operating speed of the ball mill was 350 rpm. Hence DoE was designed for a variation in grinding speed of 200–350 rpm.
