Forces in a Cone Crusher | Steel in Translation
Analysis of the forces in a cone crusher shows that, in certain conditions, the material in the crushing chamber is subjected not only to compressive forces but also to a torque. In that case, a complex stress state appears in the material. Correspondingly, normal stress and tangential stress appear in the piece.
