CONCAVES FOR GYRATORY CRUSHER

摘要

In one embodiment, concaves (10) for gyratory crushers are formed in a trapezoidal or triangular shape to achieve essentially three point contact with an external shell (2) of the gyratory crusher. In a further embodiment, concaves (20) for a gyratory crusher are provided with alignment pads (24) that are inserted between the back surface of the concave and the external shell (2) of the gyratory crusher. In a further embodiment, concaves (36) for a gyratory crushers are provided with removable fastening members such as bolts (40) that engage the back surface of the concave to mount the concave to the external shell (2) of the gyratory crusher. The concaves of the present invention can provide secure mounting of the concaves in place to promote longer wear life and are easily removed for replacement.
