Among these equipment, coal-crushing hammer heads and roller linings are common wear-resistant components used in coal crushers. Since the hammer heads endure significant impact and abrasion during operation, they require frequent replacement—resulting in increased production costs and severely impacting overall operational efficiency.

The counterattack breaker plate hammer, a critical component of the impact crusher, comes in widely available models such as 1214 and 1315 on the market. However, despite identical model names, counterattack breaker plate hammers of the same model produced by different manufacturers often fail to be universally compatible in practical applications. This discrepancy frequently leads to confusion among end customers during purchasing, sometimes even resulting in incorrect product choices.

The large jaw crusher tooth plate is a common wear-resistant and easily damaged component in jaw crushers, typically made from high-manganese steel or ultra-high-manganese steel. Based on actual operating conditions, Duma Machinery has developed a new type of micro-alloyed high-manganese steel toggle and fixed jaw plate, which demonstrates significant improvements over traditional high-manganese steel jaw crusher tooth plates—in terms of mechanical performance, wear resistance, and service life.

High-performance Austenitic Manganese Steel Crusher Hammer Heads Optimized for Cement Crushing
As wear-resistant components for hammer crushers, the manufacturing process and performance of large hammer crusher hammers directly influence the output, quality, equipment safety, and service life of limestone crushing—and even more critically, they determine the stable operation of cement production lines. Therefore, these components have drawn significant attention from both equipment manufacturers and cement-producing enterprises.

High-manganese steel, a traditional wear-resistant material, exhibits an austenitic microstructure during use. Under intense impact and compressive loads, the surface of high-manganese steel castings undergoes work hardening, increasing the hardness from its original value of approximately 200 HBS to over 500 HBW. Meanwhile, the core region of the casting retains excellent toughness.

In industries such as mining, construction, railways, and highways, crushers are core equipment, primarily used for crushing ores and rocks of medium to medium-to-hard hardness. The wear-resistant components of crushers—especially the mantle and bowl liners in cone crushers—play a decisive role in determining the efficiency of the crushing process.
