CIM’s “Bone‑Skin‑Muscle” Crusher Tooth Redefines Performance Under Pressure
The Challenge
Crusher tooth operates under extreme conditions—facing constant impact, abrasion, and crushing cycles. In demanding environments like oil sands and hard rock mining, traditional teeth often wear out in weeks, leading to:
● Frequent unplanned downtime
● High maintenance costs
● Reduced reliability and efficiency
CIM’s Solution: The “Bone‑Skin‑Muscle” Design
To address this challenge, CIM developed a revolutionary solution: the “Bone‑Skin‑Muscle” crusher tooth — a multi-material design concept that targets wear and impact resistance at every level.
Bone – Load-Bearing Backbone
The body of the tooth is reinforced with sintered Titanium Carbide (TiC) or Tungsten Carbide (WC). These materials are selected for their exceptional fracture toughness and impact resistance.
Skin – Maximum Wear Resistance
The outer layer of the tooth is made from Chrome White Iron (CWI) or PTA-welded Tungsten Carbide overlay, both known for their outstanding hardness and sliding wear resistance. This outer “armor” shields the carbide backbone from direct abrasion.
Muscle – Engineered Core Strength
The base or shaft of the tooth is made from a high-strength casting alloy, designed to absorb high loads and resist deformation. This “muscle” provides the strength to keep the structure integrity during crushing.
Advanced Manufacturing: Precision-Cast, Fully Bonded
Unlike traditional brazing or clamped-on tips, CIM’s crusher teeth are produced through a precision casting process.
● Sintered carbide inserts are pre-positioned within the mold
● Molten Chrome White Iron and alloy steel are then poured in sequence
● During cooling, the three zones metallurgically bond into one integrated structure
This process eliminates the risk of mechanical failure, such as cracking, loosening, or stud drop-out. The result is a rugged, unified wear part with no weak points — even in thermally or mechanically stressful environments.
Field-Proven Performance
CIM’s “Bone‑Skin‑Muscle” teeth have been deployed and tested in some of the harsh mining conditions — including oil sands operations in Canada and hard rock mines globally.
Customers have reported:
● Extended wear life by 2-3 times
● Reduced replacement frequency
● Lower overall maintenance costs
