What the head assembly is
The head is the moving cone at the centre of the crusher: mounted on the main shaft, driven in gyratory motion by the eccentric, and carrying the mantle on its outer face. The head assembly is that moving cone supplied as a complete unit, with its fitted components, rather than as a bare casting. The assembly's critical surface is the mantle seat. A mantle fitted on a damaged or worn seat rocks microscopically under load, and rocking manganese cracks — so the head's seat condition decides whether a correct mantle performs correctly, and the assembly and the liner are one maintenance question, not two. That relationship is the reason this component has its own page instead of a line in a list.
The recorded line
The catalogue lists a head assembly for HP cone crushers, and that listing is the recorded position: the head assembly line is recorded against the HP sizes only, and is not recorded against the GP series, Symons, any other Metso-family size or the Sandvik family. Two distinctions keep the record honest. First, the recorded line is the HP head assembly specifically; heads as a general component are a separate, general catalogue line — not recorded against the HP sizes, the GP series, Symons, any other Metso-family size or the Sandvik family — and the general line must not be read as this recorded assembly. Second, the record is an assembly-supply record: it states that head assemblies are a listed line for HP cone crushers, identified and quoted against the machine's size and original part number, with the assembly's generation within the size confirmed before dispatch.
Assembly supply, and the repair base behind it
Assembly-level supply suits planned rebuilds: the complete unit swaps in during the shutdown window, and the removed assembly becomes the plant's rebuildable spare instead of scrap. It also suits damage-led work where the head body itself is the problem — seat damage, thread damage, cracking — because the assessment is made on the whole unit. Our service record informs these enquiries directly: the published technical support record includes HP500 head assembly repair and HP500 head body repair covering locking bolt and internal thread work, set out on the repair services page. That record is a service record, not an extension of the supply record above — but it means fit and condition questions on a head assembly enquiry are answered by the team that has stripped and rebuilt these assemblies.
Ordering a head assembly
State the machine size and model, the original part number of the assembly, and — for long-lived sizes with production history — the machine's serial information if you hold it, because components can differ within a size across that history and the part number plus serial data resolves the generation. State also the condition of the mantle seat and the mating shaft surfaces if the order is damage-led. Minimum order is 1 piece, confirmed with your quotation, as is the lead time; assemblies produced to order carry their production time on the quote. Shipment on FOB, EXW, CIF or FCA terms; payment by T/T or L/C. Certificates available upon request.
| Part | Head assembly (moving cone assembly), supplied complete |
|---|---|
| Recorded position | Recorded against the HP sizes only; not recorded against the GP series, Symons, any other Metso-family size or the Sandvik family. General heads are a separate general catalogue line, distinct from this recorded assembly |
| Identification | Machine size and model + original part number; serial information where held |
| Minimum order | 1 piece, confirmed with your quotation |
Order the head assembly against size and part number
State the machine size and model and the assembly’s original part number — plus the machine’s serial information if you hold it — and, for damage-led orders, the condition of the mantle seat and the mating shaft surfaces. Minimum order is 1 piece, confirmed with your quotation, as is the lead time (typically within 15 workdays in peak season and about one month in the off-season).
