What is a High Chrome Blow Bar?
A High Chrome Blow Bar (also known as an impact crusher hammer) is the primary wear part in an impact crusher. It is the component that directly strikes and shatters the incoming feed material, such as limestone, concrete, asphalt, and demolition waste.
These blow bars are specifically manufactured from a high-chromium iron alloy. The “High Chrome” designation refers to the significant chromium content (typically ranging from 18% to 30%) in the steel, which gives the blow bar its exceptional properties. They are considered the industry standard for crushing highly abrasive materials.
The Critical Role of Blow Bars in Your Impact Crusher
The blow bar is the heart of the crushing action. Its primary function is to impart kinetic energy onto the feed material, causing it to break upon impact against the breaker plates and other blow bars. The efficiency of this process directly determines:
Productivity: Worn blow bars reduce crushing capacity and efficiency.
Product Shape: The condition of the blow bars directly influences the final aggregate’s cubical shape.
Operational Cost: Frequent blow bar replacement leads to significant downtime and part costs.
Key Features & Advantages of High Chrome Blow Bars
Why is High Chrome the preferred material for so many crushing applications? Here are its standout features:
Superior Abrasion Resistance: The high chromium content forms hard chromium carbides within the metal matrix. This makes the blow bar extremely resistant to wear caused by grinding abrasive materials, significantly outperforming manganese or low-alloy steel bars.
Excellent Hardness: High Chrome blow bars maintain a high level of hardness (often over 60 HRC), which is crucial for penetrating and breaking hard rocks.
Good Heat Resistance: The alloy offers better stability under the high heat generated during continuous crushing operations.
Cost-Effectiveness: While the initial cost may be higher, the dramatically extended service life of High Chrome blow bars results in a lower cost per ton crushed, making them more economical in the long run.
Optimal for Abrasive Materials: They are the ideal choice for processing highly abrasive materials like granite, basalt, quartzite, and recycled concrete with metal contaminants.
Custom-Made Solutions: We Match the Blow Bar to Your Material
There is no “one-size-fits-all” solution in crushing. Using the wrong type of blow bar for your specific material can lead to premature failure and unnecessary expenses. This is where our expertise comes in.
We offer fully custom-made High Chrome Blow Bars. Our engineering team will work with you to determine the optimal alloy composition, hardness, and design based on:
The Material You Crush: Is it limestone, granite, recycled concrete, or asphalt?
The Abrasiveness and Silica Content: Highly abrasive materials require a different carbide structure.
Your Impact Crusher Model and Brand: (e.g., Sandvik, Metso, Kleemann, Terex, etc.)
Your Desired Balance Between Wear Life and Impact Toughness.
By tailoring the blow bar to your exact operating conditions, we ensure you achieve maximum performance and the lowest possible operating cost.
