crusher foundations. • With spring support, the crusher and its deck are usually supported on just two beams framed into the nearest building column. Only the dead load of the crusher and deck are added to the column load, as dynamic loads are eliminated by the vibration isolation sys-tem. The layout of the structure is thus greatly simplified.

Quantifying the Vibration Level. The vibration amplitude, which is the characteristic that describes the severity of the vibration, can be quantified in several ways. On the diagram, the relationship between the peak-to-peak level, the peak level, the average level, and the RMS level of a sinewave is shown.

The operator''s exposure to vibration is negligible. Very low vibration is passed into the structure which helps to reduce damage and structure-borne noise. This method is less messy than using breakers as the debris is in larger pieces and less dust is produced. Noise levels are very low, both for the operators and the environment.
