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.

The iron scraps are removed from both fractions by using LIMS. The hammer crusher is used on the nonmagnetic fraction (> 20 mm) to liberate iron scraps which are removed again by the overband magnetic separator. The nonmagnetic fractions (Nmag F) obtained from both fractions (± 20 mm) are classified into two size fractions (± 10 mm).
