• What's the head assembly?

  Nov 26, 2025

  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.   What's parts included in the head assembly?

• What are the different manufacturing procedures for bowl assembly？

  Dec 04, 2025

  The production of the bowl assembly integrates advanced materials science and precision manufacturing technologies to ensure extreme durability, dimensional accuracy, and structural reliability as the core component of a cone crusher.     The key process flow is as follows: 1.Stringent Casting Process：Selected high-strength alloy steel is used to ensure the base material possesses excellent impact resistance and wear performance.Casting simulation software is employed to digitally simulate and optimize the pouring, cooling, and solidification processes.   2.Precision Heat Treatment：The rough casting undergoes a combined normalizing and tempering heat treatment. This process refines the grain structure, eliminates internal casting stresses, and uniformly enhances the hardness, toughness, and fatigue resistance of the material.   3.High-Precision CNC Machining：Critical mating surfaces—such as the threads that engage with the adjustment ring and the register (spigot) that fits with the main frame—are precision-machined using large CNC boring and milling machines.   4.Comprehensive Non-Destructive Testing (NDT) The finished Bowl Assembly body undergoes a rigorous multi-layered NDT inspection system:OPI (Oil Penetrant Inspection): Detects minute surface cracks or flaws.UT (Ultrasonic Testing): Examines the internal structure for voids, inclusions, or delaminations.MPI (Magnetic Particle Inspection): Identifies surface and near-surface defects, especially crucial for ferromagnetic materials.   What's parts included in the bowl assembly?
