Crusher Hammers Reinvented: Advanced Inserts. Extreme Durability.

Start with the Core: Ultra-High Chromium Composite Hammer

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.

 

  • Material Type: River pebbles, granite, manufactured sand

  • Abrasiveness & Feed Size: Very high abrasiveness; small to medium-sized feed

  • Impurity Tolerance: Low; best used in clean working conditions

Enhanced Solution 1: Ultra-High Chromium Composite Hammer with Ceramic Alloy Particle Insert

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.

  • Application Upgrade: Especially suited for high-speed sand-making lines

  • Key Benefit: Full-face ceramic reinforcement extends the striking zone’s lifespan

  • Impurity Tolerance: Still optimal for clean, silica-rich input

Enhanced Solution 2: High Manganese Steel Hammer with Ceramic Alloy Rod Insert

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.

  • Material Type: Slag, demolition debris, construction waste, high-silica rock

  • Abrasiveness & Feed Size: High; medium to large feed

  • Impurity Tolerance: Medium; tolerates occasional metal or concrete scrap

  • Key Benefit:Dual toughness and surface hardening in one

Enhanced Solution 3: Bevel Edge Ultra-High Chromium Hammer

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.

  • Material Type: Limestone, cement clinker

  • Abrasiveness & Feed Size: Medium; small to medium feed

  • Impurity Tolerance: Low to moderate

  • Key Benefit:S hank-protecting structure + hard edge performance
