Key benefits of innovations

  • Advanced Metallurgy and Precision Casting

    With an on-site foundry in place, Excel™ uses high-tin bronze alloys and centrifugal casting to deliver tougher, more wear-resistant parts with uniform grain structures. Pinch machining further improves concentricity, reducing hot spots and ensuring long-lasting, reliable crusher performance.

  • UltraNut™

    The Excel™ UltraNut™ jack-bolt locking tensioning system ensures precise preload and makes liner changes faster, easier, and safer. With protective sleeves, dust seals, and rebuildable components, it safeguards threads from wear and extends the life of critical crusher connections.

  • UltraBolt™

    The Excel™ UltraBolt™ jack bolt tensioning system delivers faster, safer, and more cost-effective mantle changes with uniform preload and easier assembly. Featuring protective sleeves, dust seals, and rebuildable components, it eliminates the need for slug wrenches or torch cutting while extending equipment life.

Innovation that drives performance

From metallurgy breakthroughs that enhance wear resistance to smarter fastening systems that simplify installation and improve safety, Excel™ innovations are purpose-built to tackle real maintenance challenges. Each advancement is engineered with the goal of extending crusher reliability, reducing unplanned downtime, and lowering total operating costs—helping your operation run more efficiently, safely, and sustainably.

Frequently asked questions

FAQs for Excel™ innovation

The UltraNut™ replaces traditional torch ring cutting with a jack-bolt locking system that applies precise preload across the head nut. This design makes liner changes faster and significantly safer by reducing the need for high-risk cutting tools, while also protecting threads with AR400 sleeves and dust seals. 

UltraBolt™ incorporates jack-bolt tensioning to achieve uniform preload without using slug wrenches or heavy torqueing methods. The system reduces installation time, simplifies disassembly, and allows for quicker mantle changes, while protective sleeves and seals extend the service life of the locking assembly. 

Using high-tin bronze alloys at the upper CDA specification improves toughness and wear resistance under heavy load conditions. Combined with centrifugal casting for dense, porosity-free grain structures and pinch machining for concentricity, these processes ensure longer wear life, reduced hot spots, and more reliable crusher performance.
