vibration levels for crushers


learn about vibration, volume 1: basic understanding of

overall or broadband vibration severity using velocity is applicable to all types of general rotating equipment iso/ansi operating at full load or speed condition. exceptions = diesel engines and rock crushers. ultra levels = .05 ips / 1.3 mm/s or less at any speed. no action required. excellent levels = .1 ips / 2.5 mm/s or less at any speed.


tools can be designed or mounted in ways that help reduce the vibration level. for example, using anti-vibration chain saws reduces acceleration levels by a factor of about 10. these types of chain saws must be well maintained. maintenance must include periodic replacement of shock absorbers.
