Toothed Roll Crusher Wear Parts Manufacturer – HighCr
Roll Crusher Tooth Segments
Roll Crushers are the workhorses of fine and controlled crushing applications. At Highcr, we understand that the Tooth Segment is the most critical component, directly impacting product size, energy consumption, and maintenance costs. We specialize in providing high-performance replacement Segment Liners and Toothed Rings that are engineered to minimize wear and maximize your machine’s potential.
Segments by Crushing Stage
Highcr segments are designed and manufactured in three distinct categories, aligning perfectly with the crushing requirements shown in your images:
| Segment Category | Application Focus (SEO Target) | Design Goal & Key Feature | Recommended Material Direction |
| 1. Primary Segments | Run of Mine (ROM) / Coarse Feed. Handling large, rugged, and high-impact material. | Deep, Aggressive Profile: Wide spacing and sharp penetration for high bite and effective handling of wet/sticky feed. Focus: Maximum material bite and Anti-Clogging. | High Manganese Steel (Mn18Cr2/Mn22Cr2): Superior impact toughness and resistance to fracture. |
| 2. Secondary Segments | Intermediate Crushing / Sizing. Reducing pre-crushed material to a controlled size for the final stage. | Medium Density Profile: Optimized tooth tips and spacing to promote shearing and compression, achieving high reduction ratios and uniform output (e.g., $-75$mm to $-50$mm). | High Chrome White Iron or Martensitic Steel: Increased hardness to resist higher abrasion levels. |
| 3. Tertiary Segments | Final Product / Fines. Producing fine, accurately calibrated final product (e.g., $-50$mm to $-30$mm). | High Density, Closely Spaced Profile: Maximizes the number of crushing points for high compression and grinding action. Focus: Ultimate abrasion resistance. | TiC Composite: Extreme hardness to combat intense grinding wear for the longest possible life. |
The Highcr Roll Crusher Difference:
-
Optimized Tooth Profiles: Custom-designed tooth geometry for each crushing stage to ensure maximum particle penetration and minimum fines production.
-
Metallurgical Excellence: Access to six specialized alloys (including our premium TiC Composites) to precisely match your material’s specific blend of impact and abrasion.
-
Lowest CPT: Our segments are guaranteed to provide superior lifespan, dramatically lowering your operational Cost-Per-Ton (CPT) ratio.
Custom Tooth Profile Design
The geometry of the tooth is the engine of efficiency. Highcr doesn’t use one-size-fits-all designs. We custom-engineer your segments based on three critical factors:
-
1. Material Analysis: We assess your feedstock’s Unconfined Compressive Strength (UCS), silica content, and moisture level to determine the optimal tooth penetration angle and profile shape.
-
2. Target Product Sizing: We adjust tooth spacing and depth to meet your required P80 or P50 finished product specifications, minimizing unwanted fines.
-
3. Dynamic Simulation: Our engineers use advanced CAD and simulation software to model wear patterns and stress distribution, ensuring the longevity of the segment under dynamic operating loads.
Materials Excellence & Durability
Highcr offers the most comprehensive material selection in the industry, guaranteeing the right balance of Abrasion Resistance and Impact Toughness for your specific segment:
| Alloy Family | Application Suitability | Highcr Advantage |
| Manganese Steel (Mn18Cr2+) | Best for Primary stage where high kinetic energy and large impact loads are present. | Ensures deep work-hardening without sacrificing core toughness or resistance to fracture. |
| High Chrome Alloys (Cr26) | Ideal for Secondary/Tertiary crushing where abrasion is dominant and impact is lower. | Provides exceptional sliding wear resistance due to high content of M7C3 primary carbides. |
| Martensitic/Low Chrome Steel | A versatile balance, offering higher bulk hardness than Mn steel while maintaining good ductility. | Excellent solution for medium-impact/medium-abrasion mixed conditions. |
| TiC Composites | Premium Solution for Tertiary/Fines. Embeds ultra-hard inserts into a tough matrix. | Achieves the longest possible lifespan by localized resistance to extreme grinding wear. |
Quality Assurance and Compatibility
-
