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.
