Noise and Vibration Pollution Reduction to a Mineral Aggregates Station through Rim Optimization in Order to Align at EU Legislation

Abstract

The paper analyzes the pollution impact of vibration on the whole human body produced by sorting and washing stations of mineral aggregates, located near inhabited areas, in accordance with national legislation. The imposed limits are correlations between the frequency of vibration with the vibration intensity, measured in vibrars. In the same time, in the EU legislation the imposed limits are given by the daily exposure limit value (acceleration of vibration movement) standardized to an eight-hour reference, measured in m/s2. The authors present a geometrical rim optimization of a mineral aggregates station to diminish the pollution produced by vibrations, that should be taken, in order to align at European legislation. Results are presented in both ways: as maximum vibration intensity and maximum vibration acceleration. Measurements were performed at normal operating capacity of the analyzed plant, based on: direct observations in the field, the existing documentation and information supplied by the business owner.
