Jan 19, 2018· For a hammer mill I would start at 70%. It's just a starting "ramp" until you current limit which with a hammer mill is just getting it rolling and not much else. 20% is where you start on a pump application and the goal is to avoid slamming or water hammer or big fans where they are high inertia but long startup at low torque is ok.
