A Few Tips for Selecting Wear-Resistant Manganese Steel Spare Parts for Crushers
When selecting crusher parts, whether the supplier can provide test certificates is an important consideration. Crusher liners are not produced on automated assembly lines; therefore, it’s crucial for manufacturers to adhere to consistent production standards to ensure reliability for users. Crusher wear-resistant component suppliers must have robust manufacturing processes and quality control systems in place—and they should be able to offer test certificates to verify that their products meet stringent production standards.

The technical team traveled to New Zealand to conduct precise mapping of crusher wear parts.
The Duma Mechanical Technology team conducted an in-depth survey of components for a 130-inch metal shredder at a major scrap metal recycling facility in New Zealand. Using a 3D laser scanner, they precisely mapped core wear parts such as hammer heads and grating plates with 0.1mm accuracy, enabling them to tailor-made wear-resistant solutions that cover the entire 60"-130" equipment range—helping customers reduce costs and improve efficiency.

Analysis of the Quality Control System for High-Manganese Steel Castings in Crusher Components
With the upgrading of domestic crushing equipment manufacturing technology, high-manganese steel castings have been widely used as core components in wear-resistant parts such as jaw plates and hammer heads—key accessories for crushers. The production of these specialized steel castings features distinct process characteristics: they are typically manufactured using a single-piece, small-batch production model, relying primarily on manual sand-mold casting techniques. Moreover, their quality-control system encompasses multi-dimensional critical factors.
