Triple/Double Roll Crushers

McLanahan roll crushers are designed for primary and secondary crushing of medium-hard to soft materials. The twin-roll design with direct drive provides efficient size reduction at low operational costs. Available in single-roll, double-roll and quad-roll configurations for different applications. Anranst supplies roll shells, segments and scraper blades in Mn18Cr2 and ZG30CrMnMo alloy steel.

Yield Strength≥ 380 MPa
GradeCSiMnCrMoNi
Mn13Cr21.05-1.20≤1.011.5-14.01.5-2.5

Excellent work-hardening capability; surface hardness increases under impact, ideal for moderate to high impact crushing conditions

Roll Shell / Tire

McLanahan roll crusher replaceable shell; smooth or toothed profile options for different applications

Mn18Cr2ASTM A128 Grade B-4 / GB ZGMn18Cr2
HardnessHB 230-300 (work-hardens to HRC 48-58)
ToughnessAKV ≥ 60J
Tensile Strength≥ 800 MPa
Yield Strength≥ 420 MPa
GradeCSiMnCr
Mn18Cr21.05-1.35≤1.016.0-19.01.5-2.5

Superior work-hardening depth; 20-30% longer life than Mn13 in high-compression applications

ZG30CrMnMoGB ZG30CrMnMo / Low-alloy cast steel
HardnessHRC 45-55
ToughnessAKV ≥ 35J
Tensile Strength≥ 900 MPa
Yield Strength≥ 650 MPa
GradeCSiMnCrMo
ZG30CrMnMo0.25-0.350.3-0.60.8-1.20.8-1.20.15-0.30

High strength and wear resistance for sizer tooth applications; verified composition with full QC documentation

Scraper Blade / Cleaner

Scraper blades keeping roll surface clean from sticky material buildup in wet crushing applications

AISI 4140AISI 4140 / GB 42CrMo
HardnessHRC 28-55 (quenched & tempered)
ToughnessAKV ≥ 45J
Tensile Strength≥ 1080 MPa
Yield Strength≥ 930 MPa
GradeCSiMnCrMo
AISI 41400.38-0.430.15-0.350.75-1.00.8-1.10.15-0.25

Forged high-strength steel for shafts, bolts and high-stress components
