About This Product
Comprehensive Overview — Material Science, Manufacturing & Application Engineering
What Is a Crusher Hammer Head?
A crusher hammer head is the core wear part of hammer crushers and impact crushers, responsible for striking and crushing raw materials (ore, rock, construction waste) into smaller particles through repeated high-impact collisions. As the component that endures the most severe mechanical stress in the entire crushing system, the quality of the hammer head directly determines crushing efficiency, product granularity, and equipment downtime costs.
ZHILI manufactures hammer heads using three primary material systems — High Manganese Steel (Mn13Cr2 / Mn18Cr2), High Chromium Cast Iron (Cr26 / Cr27), and Bi-Metallic Composite — each engineered for specific feed material hardness, impact load conditions, and service life requirements.
