Rock Breaker Hammer Heads As the core wear part of a hammer crusher, it is directly installed on the rotor of the equipment and plays an important role in impacting and crushing materials during operation. Due to the different properties of the materials being crushed, the classification of crusher hammer heads shows diverse characteristics, mainly including forged crusher hammer heads, high manganese steel crusher hammer heads, high chromium composite plate hammers, and dual-hardness alloy steel hammers.

I. Rock Breaker Hammer Heads Performance Characteristics Analysis

1. Enhanced Impact Performance: By optimizing the hammer head's center of gravity design, the linear velocity of the hammer head's center is increased, significantly increasing the impact energy on the material, thus achieving better crushing results.

2. Improved Wear Resistance: Crusher hammer heads processed with special techniques have a significantly increased effective wear amount, resulting in a significantly extended service life.

3. Optimized Output Quality: The new hammer head design effectively reduces the finished particle size while improving the equipment's processing capacity.

4. Enhanced Crushing Effect: The improved hammer head structure significantly improves the material's grinding efficiency.

II. Classification and Application of Rock Breaker Hammer Heads

Forged Hammer Heads

Forged crusher hammer heads are mainly suitable for crushing materials such as pebbles, coal gangue, and limestone. They use high-quality train wheel hub steel (65Mn material) as raw material and are formed through a precision forging process. The forging process not only eliminates internal metal defects but also optimizes the material's microstructure, maintaining complete metal flow lines. After special quenching treatment, the working area of the forged hammer head has excellent hardness (HRC56-58) and wear resistance, and its comprehensive mechanical properties are significantly superior to ordinary cast products.

High Manganese Steel Hammer Heads

High manganese steel crusher hammer heads, with their excellent wear resistance (more than three times that of traditional materials), have become the choice for large limestone crushers. This type of hammer head has the characteristics of good toughness, good processability, and high cost-effectiveness. Its unique feature is that the working surface can quickly produce work hardening under impact loads (the hardening index is 5-7 times higher than that of ordinary materials), thus forming a strong wear-resistant surface layer.

High Chromium Composite Hammer Heads

High chromium composite plate hammers use an innovative design: the hammer handle uses high manganese steel to ensure toughness, and the working area uses high chromium alloy to ensure hardness. This combination fully utilizes the advantages of the two materials and is particularly suitable for crushing high-hardness materials such as quartz and basalt. It should be noted that although pure high chromium alloy has good hardness, its toughness is poor and needs to be used with a supporting structure.

Dual-Metal Composite Hammer Heads

Dual-hardness alloy steel hammer heads are made by combining alloy materials with different properties through a special process, achieving higher hardness in key areas. The dual-hardness hammer heads developed by Duma Machinery have the following advantages:

● Maintain an excellent geometric shape for a longer time, improving material capture efficiency

● Yield strength is higher than manganese alloy, allowing for a thicker design

● Provide stronger impact force, improving crushing efficiency

● Significantly extend service life, reducing overall operating costs

In addition, cemented carbide hammer heads, with their ultra-high hardness and bending strength, effectively solve problems such as cracking and debonding that are easily encountered in traditional materials, and perform exceptionally well under special working conditions.

Various Rock Breaker Hammer Heads Each has its own characteristics. Users should select the appropriate hammer head type based on the specific material properties, operating conditions, and economic requirements to obtain excellent use effects and economic benefits.
