Typical Applications
The TC84X short-head main-shaft assembly is used in secondary and tertiary crushing circuits where a finer product gradation is required. Compared with the standard (coarse-cavity) head, the short-head profile produces a higher proportion of finished-size particles in a single pass, making it the preferred cavity for:
- Hard-rock aggregate production (granite, basalt, diabase, gneiss)
- Iron-ore and copper-ore beneficiation plants (fine crushing stage)
- Recycled-aggregate and construction & demolition (C&D) processing lines
- Cement and lime-stone preparation circuits feeding ball mills
The head and main-shaft assembly is the rotating heart of the crusher and works in conjunction with the bowl assembly (chapter 1.7, TRIO5007838) to set the closed-side discharge opening. Inspection of the head casting, main shaft and mainshaft cap is recommended every 2,000 operating hours or whenever the mantle is replaced.
Frequently Asked Questions
Q1. What material is the main shaft (TRIO17001147) made of?
Forged from 40CrNiMo alloy steel, quenched and tempered to a typical hardness of 280–320 HB. Ultrasonic testing (UT) is performed on every forging before machining, and a test certificate is shipped with the part.
Q2. Can CASTEEL supply the head casting (TRIO17001142) and the cap (TRIO17001146) separately?
Yes. Both items are available as individual castings, with or without finish-machining. We can also supply them as a matched pair already fitted with the seal ring.
Q3. Is this assembly compatible with both TC84X and TC84XR models?
Yes. TRIO17001140 is the short-head main-shaft assembly for the TC84X platform; the same assembly fits the equivalent TC84XR model year — the TC84X / TC84XR naming is a commercial designation only. When ordering, simply quote the TRIO part number(s) shown in the table above.
Q4. What is the typical lead time?
Standard lead time is 30–45 days for castings + 15–20 days for machining. Stocked main shafts and caps can be dispatched within 7–10 working days for urgent breakdown orders.
Q5. Do you provide a quality / test package?
Yes. Every shipment includes the material test certificate (MTC), UT report, dimensional inspection report, and a warranty certificate. Third-party inspection (SGS, BV, TUV) can be arranged on request.

]]>Equipment Overview
The TRIO CT4254 is a heavy-duty single-toggle jaw crusher widely used in mining, quarrying, aggregate production, and recycling for primary and secondary crushing of hard rock, ores, and demolition material. Its robust cast-steel frame and high-inertia eccentric shaft deliver consistent throughput under continuous duty.
The crushing chamber is formed by two opposing wear surfaces — the fixed jaw (stationary) and the swing jaw (reciprocating). Material is compressed and fractured between them on every stroke. Surrounding these liners, a set of supporting and clamping components keeps the wear parts seated, aligned, and tensioned so the crusher runs safely at full capacity. The seven parts listed below cover the complete wear and structural interface set for the CT4254 jaw module:
- Fixed Jaw & Swing Jaw – the primary crushing surfaces (manganese liners).
- Wedge Die, Swing (LH/RH) – clamps and locks the swing jaw liner to the swing jaw body.
- Upper / Lower Cheek Plates (RH/LH) – side liners that protect the crusher frame from abrasion.
- Wedge Block (TRIO17003948) – the hold-down / tension component that maintains liner position and crushing gap.
Available Parts List
| No. | Part Name | Part Number | Model | Function | Weight (kg) |
|---|---|---|---|---|---|
| 1 | Swing Jaw Plate | TRIO17052179 | CT4254 | Movable crushing surface mounted on the swing jaw; the high-impact wear liner that does most of the comminution work. | 2,857 |
| 2 | Fixed Jaw Plate | TRIO17052178 | CT4254 | Stationary crushing surface; the fixed wear liner against which rock is compressed and fractured. Directly determines product shape and reduction ratio. | 2,990 |
| 3 | Wedge Die, Swing LH | TRIO17003911 | CT4254 | Left-hand clamping wedge that locks the swing jaw liner firmly against the swing jaw body, maintaining crushing force and preventing liner movement. | 50.8 |
| 4 | Wedge Die, Swing RH | TRIO17003912 | CT4254 | Right-hand clamping wedge that locks the swing jaw liner firmly against the swing jaw body, maintaining crushing force and preventing liner movement. | 50.8 |
| 5 | Low Cheek Plate, LH | TRIO17003942 | CT4254 | Left-hand lower side liner protecting the frame at the discharge side; replacement restores proper chamber alignment. | 271 |
| 6 | Upper Cheek Plate, RH | TRIO17003941 | CT4254 | Right-hand upper side liner that shields the crusher frame from abrasive material flow, extending frame service life. | 387 |
| 7 | Wedge Block | TRIO17003948 | CT4254 | Hold-down / tension block that maintains liner position and crushing gap, securing the wear parts under operational load. |
Material & Manufacturing
All wear liners in this set are produced from high-manganese steel (Mn13 / Mn18Cr2) selected for its work-hardening behaviour — the surface grows harder under impact, giving excellent abrasion resistance in hard-rock service. Cheek plates and wedge components use cast carbon / low-alloy steel with precision machining for accurate fit.
Manufacturing follows a controlled process route:
- Pattern & casting – resin sand moulding with controlled chemistry and pouring.
- Heat treatment – water quenching and tempering to develop the required hardness and toughness.
- Machining & inspection – critical faces and bolt holes machined to drawing; dimensions, hardness, and surface checked.
- QC release – only parts passing inspection are packed and shipped.
OEM Quality Assurance
- Built to Original Specifications – manufactured to TRIO CT4254 drawings for 100% interchangeability with the genuine parts.
- Material Traceability – heat / batch numbers recorded; material test reports available on request.
- Strict Quality Control – dimensional, hardness, and surface inspection on every batch before release.
- Field-Proven Reliability – supplied to mining and aggregate operations across multiple continents.
Inquiry, Lead Time & Warranty
- Pricing – quote provided on inquiry; volume and repeat-order discounts available.
- Lead Time – typical 2–4 weeks depending on quantity and current foundry schedule.
- Shipping – seaworthy export packaging; worldwide delivery by sea or air.
- Warranty – 12 months against manufacturing defects.
- Customization – non-standard sizes, materials, or drawings can be produced on request.
