The foundation of Pajoa’s crusher hammer technology lies in our Ultra-High Chromium Composite Hammer — engineered for extreme abrasion environments. This hammer features a monolithic structure made from ultra-high chromium white iron, offering outstanding hardness (HRC 60–65) and exceptional wear resistance on the striking surface.
Ideal for fine crushing applications such as manufactured sand or granite, it sets the standard for durability where low impurity content and high silica input are involved.
To further improve wear life, we embed ceramic alloy particles into the impact face of the ultra-high chromium base. These fine particles create a hard-facing effect across the entire contact area, significantly reducing erosion and edge wear over extended operation.
For tougher impact environments and larger feed sizes, we offer a patented design using Mn18Cr2 high manganese steel—valued for its excellent toughness—and insert ceramic alloy rods into the high-wear zones. This hybrid construction combines fracture resistance with long wear life, even under dynamic and unpredictable loading.
For users dealing with frequent shank failures or edge deformation, this structural upgrade introduces a single-sided bevel casting design. The ultra-high chromium working edge maintains hardness, while the bevel shape helps reduce stress concentration on the shank—prolonging the hammer’s structural integrity.
When extreme solutions aren't necessary, we also provide proven wear parts in classic materials:
These are reliable, cost-efficient choices for moderate impact and abrasive conditions.
Standardteile passen nicht immer perfekt - deshalb bieten wir maßgeschneiderte Lösungen für Brecher-Verschleißteile die auf Ihre Maschine, Ihr Material und Ihre Arbeitsbedingungen abgestimmt sind.
