Cover Story: An olive oil mill formed of four conical stones used in the milling of the olive was analyzed. To this end, we studied computer-aided engineering (CAE) with a static analysis using the finite element method (FEM) of the three-dimensional (3D) model of the mill under real operating conditions. The results reveal that the conical stone mill was a robust machine. In the most unfavorable situation (blockage of one of its millstones), the highest von Mises stress was 263.9 MPa, which is far from the elastic limit of cast iron (758 MPa). The maximum displacement obtained was 2.494 mm in the inertia flywheel and the equivalent deformations did not reach 0.1% of the part dimension. Similarly, the lowest safety coefficient was 2.87, although the second lowest safety coefficient had a value of 8.69, which showed that the set was oversized. View this paper
