CIM’s Innovative “Bone-Skin- Muscle” Design for Crusher Tooth
Twin sizers or crushers are essential in mining operations, used to break down large ore chunks into smaller pieces for further processing. However, the crusher teeth—also known as sizer tips—are exposed to intense cyclic loads, severe impact, and aggressive sliding abrasion. This harsh environment often limits their service life to just a few weeks or months, depending on ore characteristics, operating conditions, and material composition, resulting in frequent replacements and high maintenance costs.
To address these challenges, Canadian Innovative Materials (CIM) has developed an advanced “Bone-Skin-Muscle” design concept to significantly improve the durability and performance of crusher teeth. This approach optimizes material selection across distinct zones of the component:
● The “Bone”: The body of the tooth is reinforced with sintered Titanium Carbide (TiC), chosen for its outstanding toughness and impact resistance.
● The “Skin”: The outer surface is composed of Chrome White Iron (CWI), providing exceptional wear resistance to shield the underlying TiC from abrasion and damage.
● The “Muscle”: The core or shaft of the tooth is made from a high-strength casting alloy designed to withstand high cyclic loads and crushing forces.

This innovative design is realized through a specialized casting process. Sintered TiC pillars are first positioned within the mold, followed by the pouring of molten CWI and alloy steel, resulting in a fully integrated structure where the three materials metallurgically bond effectively during solidification.
For even more aggressive applications, CIM has also developed an enhanced solution featuring Sintered Tungsten Carbide (Bone), Plasma Transferred Arc (PTA) welded Tungsten Carbide Overlay (Skin), and high-strength Alloy Steel (Muscle). This system offers superior performance in extreme wear environments.
Both “Bone-Skin-Muscle” solutions—TiC-CWI-Alloy and Tungsten Carbide-PTA-Alloy—have been successfully deployed in primary and secondary crushing operations within oil sands mining, delivering longer service life and significantly reducing replacement and maintenance costs.
