Basic Safety Checks for Hammer Mills. In terms of safety checks, Jim recommended the following: Using a magnetic separator to ensure that tramp metal doesn't come into the mill itself. Prevent buildup in the grinding chamber, so that heat doesn't create a source of ignition. Checking to make sure that the bearings are not running hot.
