"Gyro crusher"

Priority." USA ₉ of June 21, 1963, Fr ₃ 739 008

The invention relates to gyratory crusher ntt voa housing borne, drivable eccentric whose crusher head is on the Eccentric is mounted, and with bearings, swiaehen eccentric and Breeharkopf, such that a rotary movement toib eccentric the crusher head is transferred.

Usually the crusher head of a rotary crusher is on mounted on an eccentric bushing, via the rotary drive of which an Ereiaalbewegung on the Breeherkopf within the crusher chamber is exercised.

The problem which often occurs with crusher breakers ₉ can be seen in the fact that when starting a crusher, the crusher is essentially not subject to any stress

Rotating achee without a load condition is now essentially prevented by the braking effect exerted by engagement of the plates 64 and 86 connected to the torsion elements -58 and thus anchored against rotation, the brake lining or friction material 84 being caused by the on the Breoherkopf 18 supported plate 76 was worn.

While the torsion bar 68 has been described as a flexible, cable-like element, a fixed Tor bionetab may be used instead, as described in U.S. Patent 5,227,381 entitled "Cone Breaker ¹ '- Karl Gplucke - from Jan. 4, 1966. If a rigid torsion bar is used, it should be connected on both sides with a pivotable connection to the plate 40 and to the plate 64 or the bushing 66 similar to the connection of the Toreionselenentee 68 bit of the plate 40 in Figures 1-3 or similar Way with the pivot bearing assembly of the torsion rod, as is Darge in said US Pat.
