In this work the hydrodynamics behaviour of a horizontal vibrofluidized bed (VFB) is analyzed through pressure drop versus air velocity and standard deviations of pressure drop versus air velocity curves with different vibration conditions. The influence of parameters such as frequency and vibration amplitude, as well as bed material loaded, were evaluated and quantified through statistical analysis. A strong linear mass influence was observed on the bed pressure drop for all amplitude levels. For the amplitude it was observed a quadratic function related to pressure. The lowest level of vibration frequency there were the higher velocity values, and they were more accentuated for the intermediate amplitude levels. We found higher values for the minimum vibrofluidization velocity for the same condition of higher mass and intermediate values of amplitude.
