What are Ceramic Blow Bars?

Metal Matrix Composites (MMC) Ceramic Blow Bars also known as Cearmic Blow Bars, include:

  • Chrome Iron Matrix with Ceramic Composites Blow Bars;
  • Martensitic Alloy Steel Matrix with Ceramic Composites Blow Bars;

Ceramic Blow Bar is one of the most common impact crusher wear parts. It combines the high resistance of the metal matrix with extremely hard ceramics.

Porous preforms made of ceramic particles are produced in the process. The metallic molten mass penetrates into the porous ceramic network.

    Metallurgy of the Metal Matrix Ceramic Blow Bars

    The combination of metal matrix and extremely hard ceramics makes the blow bars especially wear-resistant but at the same time very impact-resistant. With blow bars made of composites from the field of ceramics, a service life that is three to five times as long as that of martensitic steel can be achieved.

    Martensitic Alloy Steel Matrix + Ceramic Composites

    Martensitic alloy steel with ceramic is a premium composite metallic matrix steel with hard ceramic alloy inserts on the wear surface. The hard alloy ceramics combined with martensitic steel matrix provides a significant working life advantage over standard martensitic steel blow bars.

    • This material is commonly used in recycling industries and primary crushing in quarries. Certain applications are unsuitable for this material, including limestone crushing and slag recycling.
    • E.g. primary crushing of sandstone mine, construction waste recycling, concrete, natural stone.

    Chrome Iron Matrix + Ceramic Composites

    Chrome Iron with ceramic is a premium composite metallic matrix iron with hard ceramic alloy inserts on the wear surface. The hard alloy ceramics combined with either medium chrome or high chrome iron matrix provides a significant working life advantage over standard chrome iron bars.

    • Whilst this material can be very successful in secondary applications, it should not be used for primary crushing or very hard and abrasive applications.
    • E.g. secondary & tertiary crushing of sandstone mine, pre-crushed concrete, asphalt recycling (metal-free), metal ore crushing, etc.
