### Experimental (OMA) and Numerical (FEM) Modal Analysis .

Abstract The paper presents the results of the modal analysis of a ball mill foundation, an element of the processing technological line in an ore enrichment plant in Poland. The modal analysis was performed in two ways: numerically, using FEM, and experimentally, using OMA. The analyses results were validated and the FEM model was tuned appropriately. The results show a surprisingly good ...

### Flotation Circuit - an overview | ScienceDirect Topics

The rod mill test gave RWilab of 14.5 kWh t −1 and a ball mill work index BWilab of 13.8 kWh t −1. Accepting that the rod mill work index applies to size reduction of the circuit feed down to the rod mill test product P 80 of 1050 µm and that the ball mill work index applies from this size to the circuit product size, calculate the standard Bond energy for the circuit.
