High Speed Hammermills For Fine Grinding: Part 6 - Other Considerations

Other Considerations

Magnetic protection is necessary in order to realize the best life of the working components of the mill. Tramp iron that enters a hammermill can knock holes in the screen, break hammers, and create undesirable sources of ignition. Mills that routinely operate with excessively worn or failed hammers will vibrate badly and promote bearing failures. The vibration monitor switch on a hammermill is intended to be used as an emergency shut down measure in case of a failure within the hammermill.

Always buy the best possible magnetic protection that is reasonable for a specific system and make sure the magnets are routinely cleaned. Magnets are relatively cheap insurance against damage due to foreign objects, but must be cleaned regularly to insure they continue to operate at maximum performance levels.
