INERTIAL GYRATORY CRUSHER Russian patent published in 1995 - IPC

FIELD: technique of solid material crushing. SUBSTANCE: inertial gyratory crusher has body with outer concave 1 and inner crushing head 2, debalance mass 3 installed on shaft 4 of inner crushing head 2 and conjugated with spherical end 5 of drive shaft 6. Weight 7 is connected in its middle part with drive shaft 6 by means of trunnion 8 whose axis is square to axis of drive shaft 6 and in the upper part, it is conjugated with unbalanced mass 3 which is made in form of weight unbalanced relative to axis of drive shaft 6. Static moment of unbalanced mass is equal to static moment of weight 7 and is located in antiphase relative to weight 7. During rotation of drive shaft 6, weight 7 pushes unbalanced mass 3 and centrifugal force developed by unbalanced mass 3 is applied via shaft 4 to inner crushing head 2. Centrifugal force developed in weight 7 makes it turn on trunnion 8 thus exerting additional pressure with its upper part to unbalanced mass 3 and via it to inner crushing head 2. EFFECT: higher efficiency of crushing and reduced metal content of design. 1 dwg
