Product Overview

A maintenance kit of CH440 spare parts — the supporting components that sit around the crushing chamber of the CH440 / H4800 cone crusher: the head nut and burn ring that clamp the mantle on the cone head, the dust and oil seal rings and O-rings that keep dust out of the eccentric and lubrication circuits, the spider bushing and spider cap that locate and protect the top of the main shaft, the main shaft sleeve, and the hydraulic filter cartridges and spin-on filter element that protect the lubrication system.

These are the parts normally ordered alongside a liner change or scheduled overhaul. They are supplied together so a shutdown can be completed in one pass without waiting on individual components, and so seal and filter items are replaced at the right interval rather than being reused past their service life.

CH440 Spare Parts List

Equipment Overview

The CH440 (also designated H4800) is a hydrocone-style secondary or tertiary cone crusher used in aggregate production, quarrying, mining and recycling. Around the crushing chamber, a number of support, sealing and filtration components keep the machine running between liner changes: the head nut and burn ring lock the mantle onto the cone head; the dust seal ring و oil seal ring separate the crushing chamber from the eccentric and lubrication spaces; the spider bushing و spider cap take the top bearing load of the main shaft; and the filter cartridges keep the lubrication oil clean. Neglecting these items is a common cause of premature bearing wear, oil contamination and unplanned downtime.

Component Notes

• صامولة رأس صامولة رأس/حلقة حرق — clamps the mantle down on the cone head; the burn ring backs the nut so it cannot loosen under crushing load.
• Dust Seal Ring / Oil Seal Ring / O-Ring / Seal Ring — the sealing set that stops rock dust reaching the eccentric and stops lubrication oil escaping. Seal items should be replaced at every liner change rather than reused.
• جلبة العنكبوت — the upper bearing surface that steadies the top of the main shaft inside the spider.
• قبعة العنكبوت — covers and retains the spider bore, keeping dust and water out of the top bearing.
• جلبة العمود الرئيسي — protects the main shaft where it passes through the sealing and bearing areas.
• Filter Cartridges and Spin-On Filter Element — protect the lubrication circuit; a clogged element raises oil temperature and accelerates wear on the eccentric and gears.
• Hydraulic Pump, Hydroset Relief Valve and Pressure Indicator — the hydroset circuit that sets and holds the closed-side setting: the pump moves the oil, the relief valve protects the circuit from over-pressure, and the pressure indicator (PIS 3097, 2.2 bar) shows the clamping pressure directly on the machine.

Scheduled maintenance and liner changes on CH440 / H4800 cone crushers in quarry, mining and recycling plants, plus the equivalent CH420 and CH430 filter elements where the same lubrication circuit is used. Keeping the correct sealing and filtration components in stock is what keeps a cone crusher available through the crushing season.

Product Overview

This is a complete wedge assembly set for the TP450 cone crusher, comprising the wedge body together with its matching bolts and nuts — the components that clamp and secure the mantle and bowl liner in the crushing chamber. Manufactured by MiningSpares from cast steel with a durable painted finish, the set is supplied as a matched kit so that the wedge, bolt and nut threads are fully compatible and fasten correctly under load.

Wedge Assembly Components

Equipment Overview

The TP450 is a heavy-duty cone crusher widely used in mining, quarrying and aggregate production for secondary and tertiary crushing of hard rock and ores. Inside the crushing chamber, the mantle is mounted on the main shaft and the bowl liner is held in the upper frame; both are locked in position by a ring of wedge assemblies. Each wedge presses the liner against its seating face, while the bolt and nut clamp the wedge in place and maintain the preload as the machine operates.

Why the Wedge Set Matters

• Correct liner clamping — a worn or loose wedge lets the mantle or bowl liner shift, causing uneven wear, poor product shape and possible damage to the frame seating faces.
• Matched kit — wedge, bolt and nut are supplied together so thread pitch, hardness and geometry are compatible and torque correctly.
• Service accessibility — the wedge design allows liner changes to be carried out with standard tooling during scheduled maintenance shutdowns.
• Corrosion protection — the painted finish limits rust during storage and shipment, keeping the assembly free-running at installation.

Typical Applications

The TP450 cone crusher and its wedge assembly set are used in hard rock mining operations, stone quarries, sand and gravel plants, cement and industrial mineral processing, and construction and demolition recycling — wherever secondary or tertiary crushing of abrasive material is required.

The assembly reference number (TRIO TRIO17001140) corresponds to chapter 1.6 HEAD AND MAIN SHAFT ASSEMBLY of the TC84X Parts Manual and contains 7 line items as listed below. Each part can be supplied individually or as a complete short-head main-shaft assembly; please quote the TRIO part number(s) when ordering.

Aftermarket replacement parts compatible with TC84X cone crusher. Not affiliated with or endorsed by the original equipment manufacturer.

1.6 Head and Main Shaft Assembly (Short Head) — TRIO17001140

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.
