BLOWBARS
 
  Crushing activities in mining, quarrying or recycling industries are carried
  out by the several types of impactors, i.e. Vertical Shaft Impactors (VSI) or
  Horizontal Shaft Impactors (HSI). In the particular case of a horizontal shaft
  impactor, the rotor is the central part in the machine. That can be fitted either
  with four laterals of x hammers or with four blowbars positioned in a star    shape.
 
  When turning, the rotors will rotate the hammers or blowbars at a certain speed
  in order to break the raw material fed in through the top of the machine.
  According to the machine type, we develop different designs and
  manufactures different alloys of blow-bars.
 
 
The target is to find the design that will break the raw material at the highest efficiency according to the predefined criteria of shape, size,…) and the alloy that will resist against wear and shocks in order to keep the blowbar’s original profile constant, and hence enable the best performance in terms of quantity (tons crushed per day) and quality (requested cubicity, granulometry, …).
 
Key Benefits:
High lifetime, + 80-120 % against monometallic martensitic steel.
Low risk of breakage.
Reduced cost per ton.
Reduced maintenance.
Improved crusher productivity.
 
Options for Blowbar Metallurgy
MANGANESE
Manganese blow bars are predominantly employed in primary crushing scenarios, offering superior impact resistance compared to other blow bars. This alloy is particularly effective in environments where the presence of tramp iron is anticipated. However, it should be noted that this bar may not withstand abrasive wear as effectively as certain alternative alloys in our range.
 
MARTENSITIC
Martensitic blow bars are frequently employed in applications demanding high impact resistance and comparable abrasive wear resistance to chrome irons. Suitable for both primary crushing and recycling operations, these bars can handle larger feed sizes compared to chrome iron and can also withstand moderate levels of tramp iron. However, it is advised against their use in highly abrasive materials.
 
MARTENSITIC CERAMIC 
A combination of martensitic steel and ceramic matrix uniformly distributed across the bar. This configuration provides the advantages of our standard martensitic alloy along with enhanced wear resistance due to the ceramic inlay. Primarily utilized in primary crushing and recycling operations involving moderately abrasive materials. However, this alloy may not accommodate very large feed sizes as effectively as standard martensitic or manganese alternatives.
 
CHORIMIUM IRON
Widely utilized in horizontal impact crushers, chromium iron offers remarkable resilience against abrasive wear under suitable conditions. It's crucial to regulate feed size and metal content, as this alloy tends to be more brittle compared to other alloys, potentially leading to breakage. Generally, this alloy finds its application in secondary, tertiary, or recycling operations dealing with abrasive materials.
 
CHROME CERAMIC
A chrome alloy infused with a ceramic matrix spanning the entire bar offers superior wear resistance in extremely abrasive materials compared to any other alloy. Typically employed in secondary, tertiary, and asphalt applications where the presence of tramp iron is unlikely, the chrome ceramic bar stands out. Combining ceramics with either medium or high chrome content significantly enhances wear life, surpassing that of regular chrome bars when utilized in appropriate applications.
