<p>A gyratory crusher comprises an eccentric (10) provided with a first envelope surface (46a, 46b) and a second envelope surface (48a, 48b). A third envelope surface (44a, 44b) extends about a central axis (A) and has a longitudinal extension along said central axis (A). A first slide bearing (34a) and a second slide bearing (34b) are provided between the first (46a, 46b) and third (44a, 44b) envelope surfaces. The first and second slide bearings (34a, 34b) are vertically separated from each other such that a distance-to- height quotient (VDi/H1; VDi/H2) of the first or second slide bearing (34a; 34b) that has the greatest height (H1; H2) is greater than 0,8.</p> |
