Abstract
The anti-spin system is applied to a cone crusher having a structure () carrying an upper housing () and a vertical axle (); an eccentric element () to be rotated around the vertical axle (); and a cone head () disposed inside the upper housing () and being axially and rotatively supported on the structure () and radially supported around the eccentric element (). The anti-spin system comprises a braking bush () carried by the cone head () or by the structure (), and an annular shoe () carried by the other of said parts, which are pressed against each other, by action of the inertial centrifugal force acting on the cone head (), upon 'no-load' operation of the crusher, to generate a friction force opposite and superior to that generated between the cone head () and the eccentric element () and to prevent the latter from rotatively dragging the cone head ().
