The head assembly is the central moving component of a cone crusher. Its core components include the Head, the Head Ball, the Upper Head Bushing, the Lower Head Bushing, and the T-Seal. The material of upper and lower head bushing is bronze, it's protect the the wearing of main shaft.

Primary Functions:
1. Gyratory Motion: Driven by the eccentric mechanism, the entire head assembly generates a precise gyratory motion. This creates the crushing action necessary to process feed material.
2. Material Comminution: As the mantle attached to the head moves close to the stationary bowl liner, the rock is subjected to multiple cycles of compression, impact, and breakage within the crushing chamber. This repeated process efficiently reduces the material to the desired size.
3. Material Discharge: When the head moves away from the bowl liner, the gap increases, allowing the crushed product to gravitate downward and discharge from the bottom of the chamber, continuing its path through the circuit.
