As a high-quality supplier of crusher spare parts in China, Duma Machinery specializes in manufacturing premium-quality accessories for cone crushers used in iron ore beneficiation plants, crusher spare parts, and wear-resistant components for various types of mining equipment. Cone crushers are commonly used for secondary or tertiary crushing in industries such as mining, metallurgy, and construction. Cone crusher parts refer to the collective term for numerous wear parts used in hydraulic, compound, and other types of cone crushers. Fixed cones, moving cones, and liners are just a few examples of the cone crusher wear parts we offer from our foundry. In addition, we provide custom-made services, producing parts based on drawings submitted by our customers. We not only offer standard models but also manufacture wear-resistant components tailored to specific customer requirements, ensuring perfect compatibility with equipment from leading brands.
Engineers at Duma Machinery have been deeply involved—from start to finish—in the design of high-quality wear parts for cone crushers. Our stationary and moving cone liner plates for cone crushers have proven to deliver superior performance in real-world applications, even outperforming the original equipment manufacturer’s products. We conduct rigorous engineering evaluations and wear analyses on crusher cone liners, aiming to extend their service life and boost production output through customized designs. By collaborating with numerous crusher manufacturers, we’ve minimized risks to the greatest extent possible and ensured that our crusher wall liners—meeting our stringent quality standards—are offered at the most competitive prices. Duma Machinery’s moving cone wall liners have already extended service life by up to 50% or increased production output by 10%. In nearly 100% of the tests conducted on crusher cone liners, their performance has either matched or exceeded that of existing products.
High-Chromium Ceramic Inserted Plate Hammer – Impact Crusher Plate Hammer DM-12
The specialized high-chromium ceramic hammer for impact crushers utilizes a gradient cladding process to metallurgically bond a high-chromium alloy matrix with a ceramic-reinforced layer. These impact crusher hammers are suitable for high-abrasive applications such as secondary and tertiary crushing of sandstone ores, pre-crushing concrete, asphalt recycling (non-metallic), and crushing metallic ores.
In the fields of mining and construction engineering, the jaw crusher serves as the core equipment for raw material crushing, and the performance of its key component—the jaw plate—directly affects the overall efficiency of the machine. As a professional jaw plate manufacturer, Duma Machinery will systematically introduce you to the classification of jaw plates, their material characteristics, and solutions for optimizing service life.
