The − 100 + 40 mm feed particles were crushed in the hammer mill under different levels of the feed flow rate and rotor speed.A grate with a 20 mm opening was used at the discharge end.However, tests were also carried out after removing the grate to study the effect of the grate on the generation of fines.

These mills are "overrunning" machines, reducing material on breaker plates and then crushing on grates. They are designed for operations that need processed feed before reaching the discharge area.
