Duma Machinery—Specializing in providing high-quality spare parts for crushing equipment and wear-resistant solutions for mining machinery.
Duma Machinery offers products under its own brand. Crushing equipment spare parts Wear-resistant parts for mining equipment and various wear-resistant spare parts for mining applications are widely used in gold mining, iron ore mining, rare-earth mining, as well as in fields such as aggregate production, cement manufacturing, and fertilizer raw material processing. Our customers handle thousands of tons of rock every day, and crushing costs account for more than 60% of the entire production cycle—among which replacing worn-out parts represents a significant expense. Duma Machinery’s high-performance crusher spare parts can substantially reduce production costs, extend maintenance intervals, and minimize downtime.
Core products: Moving cone crushing wall & stationary cone mantle wall
We offer a complete range of cone crusher parts for stone, including:
- ● Movable Cone Lining (Crushing Wall)
- ● Fixed Cone Lining (Crushing Wall)
- ● Cutting torch ring
- ● Distributor cover
- ● Crusher back lining
All products are made from high-quality, ultra-high-manganese steel castings, ensuring exceptional wear resistance and impact resistance.
Wear-Resistant Materials Science: Optimizing the Performance of Spare Parts for Crushing Equipment
Duma Machinery has developed a variety of alloy formulations to meet the requirements of different operating conditions.
- Crushing Wall & Crushing Wall Lining板 Castings made of ultra-high-manganese steel grades A, C, D, D1, and D2 are used, with additional strengthening elements such as molybdenum, nickel, and titanium added under heavy-duty operating conditions.
- Other wear-resistant spare parts for mining applications Select high Brinell hardness wear-resistant steel or high-chromium white cast iron to ensure service life under extreme conditions.
We optimize material selection based on the stress conditions in different regions of the crushing chamber:
- Lower row (high-wear area) It uses a special steel with enhanced wear resistance.
- Top row (high-impact area) Select materials with excellent work-hardening capabilities.
Comparison of Grades for Austenitic Ultra-High Manganese Steel Castings
Level Ingredients Applicable scenarios Advantage Grade A Mn 13% General-purpose High structural strength, with a significant increase in hardness after work hardening. Class C Mn 13% + Cr 2% Moderately abrasive rock Higher tensile strength and superior wear resistance compared to Grade A. Class D Mn 18% + Cr 2% High-impact operating conditions After heat treatment, the hardness reaches 270 HB, and wear resistance is improved by 20%. Level D1 Mn 22% + Cr 1% Ultra-hard rock (initial crushing stage) Ultra-high impact strength Level D2 Mn 22% + Cr 2% Highly abrasive rock (secondary/tertiary crushing) Duma high-wear-resistant ultra-high-manganese steel castings Product Parameters
