High Manganese Steel Bowl Liner for High-Abrasion Granite Crushing Service Life Increased by Over 30%

Customer Background

Industry: Mining & Aggregate Processing
Region: South America
Crusher Type: Medium to Large Cone Crushers
Compatible OEMs: Metso Nordberg, Sandvik
Annual Throughput: 2.8–3.5 million tons
Material Processed: High-abrasive granite with high SiO₂ content
Operating Mode: Continuous, high-load operation

The customer operates a large-scale aggregate crushing plant processing highly abrasive granite.
Due to the combination of high hardness and strong abrasiveness, the original OEM bowl liners experienced rapid and inconsistent wear, resulting in frequent liner replacement and unplanned downtime.

Average service life of previous bowl liners was only 3.5–4 months, leading to increased maintenance cost and reduced crusher availability.

Application Challenges

Short and unstable bowl liner service life

High liner replacement frequency

Increased downtime and maintenance labor

Rising cost per ton of crushed material

Requirement for an aftermarket bowl liner without modifying crusher structure

Manganese Steel Grades for Bowl Liners

Haitian Heavy Industry offers multiple manganese steel liner grades to suit different crushing applications.

All grades can be supplied with or without chromium alloying to further enhance abrasion resistance.

Chemical Composition of Manganese Steel Bowl Liners

Chromium content can be adjusted between 1.0% and 2.5% for severe abrasion applications.

Manganese Steel Selection Based on Rock Type

Selecting the correct bowl liner material is critical for performance and liner life:

Hard & Abrasive Rock → 18% or 22% Manganese Steel

Hard & Non-Abrasive Rock → 18% Manganese Steel

Medium Hard Rock → 13% or 18% Manganese Steel

Soft & Abrasive Rock → 18% Manganese Steel with Chromium

Soft & Non-Abrasive Rock → 13% Manganese Steel

This ensures stable wear patterns, effective work hardening, and predictable liner life.

Manufacturing Process & Quality Control

One-piece sand casting for structural integrity

Strict control of chemical composition and pouring parameters

Solution heat treatment followed by water quenching

Full inspection to ensure proper fit and consistent wear performance

All bowl liners meet or exceed industry standards for chemical composition and mechanical properties.
