(57) A cone crusher comprising a mantle fixed to and rotatable with a head shaft about which an eccentric weight or unbalanced mass is relatively rotatable, the head shaft and eccentric being commonly driven by a friction drive which permits a degree of angular movement of the rotational axis of the head shaft relative to the rotational axis of the friction drive. In accordance with the invention means is provided for supplying a lubricating fluid under pressure from the friction drive to the interior of the head shaft, the head shaft having at least one radial bore which communicates its interior with the peripheral surface of the head shaft at a position where the shaft is surrounded by the eccentric.
