BUSHING ASSEMBLY AND DRIVE MECHANISM FOR ECCENTRIC CRUSHER

Abstract

A bushing assembly (50) for an eccentric machine such as a rotary crusher (1). The bushing assembly (50) comprises a first bushing (51) having a central shaft (105) and a first cavity (53) coaxial with a first eccentric shaft (106). A second bushing (61) having a second central shaft (205) is housed in the first cavity (53). The second bushing (61) has a second cavity (65) coaxial with a second eccentric shaft (206). The first bushing (51) and the second bushing (61) are configured to rotate individually at different relative speeds, such that the distance between the second central shaft and the first eccentric shaft varies.
