An improved cone-style rock crusher. The rock crusher may be adjusted for varying rock crushing specifications, including different speeds, throws, and liners. The rock crusher comprises a frame that supports a crushing bowl, a crusher head and a shaft, with the shaft being secured to the crusher head. A domed feed plate may be secured onto the crusher head for assistance in secondary rock crushing processes. An eccentric bushing allows the shaft to be aligned properly, regardless of whether there is a load or not within the crushing bowl. The bushing is tapered downwardly, which allows for evenly dispersed contact along the length of the shaft as it gyrates. Furthermore, the thickness of the bushing is asymmetrical. The rock crusher further comprises uniquely designed tramp release cylinders that provide a safeguard that acts as shock absorbers when the rock crusher encounters tramp material.
