In a ball mill, the particles are ground by repeated impact forces. The material usually needs more than 20 minutes of grinding from mill entrance to outlet, with uncountable impacts take place on this way. Depending on the efficiency of the separator and the Grinding Aid, agglomerates of fine particles are rejected and pass the ball mill again.
