Abstract
A cone crusher includes a stationary main shaft and an eccentric that rotates about the main shaft to cause gyrational movement of a head assembly to crush rock within a crushing gap. The cone crusher includes a counterweight assembly mounted for rotation with the eccentric. The counterweight assembly includes a counterweight body having a series of tanks. Each tank can receive either a first ballast and a second ballast or a combination thereof. The first ballast is formed from a material having higher density than the second ballast to increase the concentration of weighting in desired locations around the counterweight assembly.
