HAITIAN Heavy Industry Supports South African Mining Customer with Wear-Resistant Solutions

Customer Background

On June 29, 2026, a South African mining customer visited HAITIAN Heavy Industry’s manufacturing facility for technical discussions on improving wear part performance under high-abrasion and high-impact mining conditions.

During mining operations, crusher wear parts often face rapid wear, uneven failure, and impact damage, resulting in shorter maintenance cycles and reduced production efficiency.

With years of experience in high-chromium wear-resistant castings, HAITIAN provides customized solutions to help global mining customers improve equipment reliability and service life.

Factory Visit Overview

Accompanied by HAITIAN’s technical and international sales teams, the customer visited the company’s key production facilities, including:

· High-chromium alloy casting line

· Heat treatment system

· CNC machining center

· Quality inspection laboratory

The main products discussed included:

· Jaw Crusher Plates

· Cone Crusher Liners

· Blow Bars

· Mill Liners

The customer focused on material performance, wear resistance, and service life stability under actual mining conditions.

Customer Challenges

1. Fast Wear Under High-Abrasion Conditions

When processing hard ores such as granite and iron ore, the customer experienced:

· Rapid wear of jaw crusher plates

· Uneven wear of cone crusher liners

· Shortened service life of wear layers

These issues increased maintenance frequency and affected production efficiency.

2. Cracking Under High Impact Loads

During impact crushing operations, blow bars showed edge chipping and crack expansion, affecting equipment stability.

3. Unstable Service Life Between Batches

Hardness variations between different batches made it difficult for customers to establish reliable spare parts management.
