Problematic mill vibration Natural resonances of the rolling mill involve translational motion of the rolls This typically occurs at frequencies greater than 50Hz Of the large number of these resonant modes that could become excited during rolling only a few will cause damage to the metal in the mill or the surfaces of the rolls

Vibration sensors eg accelerometer Careful selection of a suitable hammer and tip is important for a successful bump test In general a softer often also larger hammer tip provides higher amplitudes of exciting frequency components of the impact force a narrower force spectrum and a lower exciting frequency

Hammer Mill Noise Control Hammer Mills work on the principle that most materials will crush or pulverize upon impact using a three step operation This operation can be very noisy and loud eNoise Control provides noise control solutions appropriate for hammer mills Material is fed into the mill’s chamber typically by gravity

This is accomplished by eliminating hammer resonances in the frequency range of interest from corrupting the test data resulting in more accurate and consistent measurements The force sensor provides a measurement of the amplitude and frequency content of
