Wear-Resistant Material Science: Optimizing Stone Crusher Machine Spare Parts Performance

Duma Machinery has developed a variety of alloy formulas to meet different operational conditions:
● Concave wall & rock crusher mantle liners: Made from A, C, D, D1, D2 grade manganese steel castings, with additional strengthening elements such as molybdenum, nickel, and titanium for heavy-duty conditions.
● Other mining spare parts: Made from high Brinell hardness wear-resistant steel or high-chromium white cast iron, ensuring long service life in extreme conditions.
We optimize material selection based on the stress conditions of different areas of the crushing chamber:
● Lower discharge (high wear area): Special steel with superior wear resistance.
● Upper discharge (high impact area): Materials with excellent work-hardening ability.
