Product Overview

Matched wear parts for the CH440 / H4800 cone crusher: the 440 concave (442.8421) and the B-profile mantle (442.7230). Both are cast in M7 high manganese steel and machined on the seating and clamping faces so the cone head and upper frame locate correctly, keeping the closed-side setting and chamber geometry within specification.

Wear Parts List

Material and Casting

• M7 high manganese steel — the M7 grade is a work-hardening austenitic manganese casting (Mn18Cr2 type) that develops a hard wearing surface under load while the core stays tough enough to pass tramp metal. The grade is stamped on each casting for traceability.
• Water-glass sand casting with controlled heat treatment for a uniform austenitic structure.
• Machined seating and clamping faces so the concave beds down square in the frame and the mantle seats correctly on the cone head.
• B-profile cavity geometry matched to the original chamber specification.

Applications

Suited to secondary and tertiary crushing of granite, basalt, limestone, river gravel, iron ore and construction and demolition waste. Replacing mantle and concave as a matched set avoids eccentric wear and keeps the setting stable through the wear cycle.

Product Overview

High manganese steel wear parts for the MCO9 mobile cone crusher: the Mantle STD (2295672) and the matching Torch Ring (2545973). The mantle is the moving crushing member mounted on the cone head, and the torch ring sits beneath it retaining and sealing the mantle assembly on the head — the two parts are normally replaced together during a liner change.

Wear Parts List

Equipment Overview

The MCO9 is a mobile cone crusher used as a secondary or tertiary stage in aggregate production, quarrying and recycling. Material is crushed between the mantle, which gyrates on the cone head, and the stationary bowl liner in the upper frame. Because the mantle carries the moving side of the crushing action, its wear profile controls the closed-side setting and the finished product shape — a worn mantle widens the gap locally and produces oversize and flaky material.

Material and Casting

• Mn18Cr2 high manganese steel — work-hardening austenitic manganese casting, giving a hard wearing surface under load with a tough core to survive tramp metal.
• Water-glass sand casting followed by controlled heat treatment for a consistent austenitic structure.
• Machined seating faces so the mantle pulls down square on the cone head and the torch ring beds correctly without rocking.
• Profile matched to the standard (STD) cavity for correct nip angle and throughput.

Applications

Suited to secondary and tertiary crushing of granite, basalt, limestone, river gravel, iron ore and construction and demolition waste. Wear life depends on feed grading, the closed-side setting and the abrasiveness of the rock; replacing the mantle and the torch ring as a set avoids the sealing and retention problems that arise from mixing new and worn components.
