CJ Jaw Crushers

Sandvik CJ series jaw crushers are engineered for maximum productivity in primary crushing. The deep symmetrical crushing chamber, combined with optimized kinematics, delivers up to 30% more capacity than conventional jaw crushers. CJ series models from CJ211 to CJ412 handle throughput up to 700 tph. Anranst provides jaw plates in Mn13Cr2 and Mn18Cr2 with optimized tooth profiles for different feed conditions.

Jaw Plate (Fixed & Swing)

Primary crushing surfaces for CJ-series jaw crushers; wedge-shaped crushing chamber with optimized nip angle for high throughput

Mn13Cr2ASTM A128 Grade B-2 / GB ZGMn13-2
HardnessHB 210-260 (work-hardens to HRC 45-55)
ToughnessAKV ≥ 80J
Tensile Strength≥ 750 MPa
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

Mn18Cr2ASTM A128 Grade B-4 / GB ZGMn18Cr2

Yield Strength≥ 420 MPa
GradeCSiMnCrMoNi
Mn18Cr21.05-1.35≤1.016.0-19.01.5-2.5

Higher Mn content provides superior work-hardening depth; 20-30% longer service life than Mn13 in high-compression applications

Mn22Cr2MoPremium Hadfield / GB ZGMn22Cr2Mo
HardnessHB 250-320 (work-hardens to HRC 50-60)
ToughnessAKV ≥ 50J
Tensile Strength≥ 850 MPa
Yield Strength≥ 450 MPa
GradeCSiMnCrMoNi
Mn22Cr2Mo1.10-1.40≤1.020.0-24.01.5-2.50.30-0.60

Ultra-high Mn + Cr-Mo alloying; maximum work-hardening depth for extreme impact conditions; 30-50% longer life than Mn18

Cheek Plate (Side Liner)

Protects CJ jaw crusher side walls from material abrasion and scalping

Mn13Cr2ASTM A128 Grade B-2 / GB ZGMn13Cr2
HardnessHB 210-260 (work-hardens to HRC 45-55)
ToughnessAKV ≥ 80J
Tensile Strength≥ 750 MPa
Yield Strength≥ 380 MPa
GradeCSiMnCr
Mn13Cr21.05-1.35≤1.011.0-14.01.5-2.5

Standard work-hardening steel; cost-effective for moderate impact applications

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

Toggle Plate

Safety toggle for CJ series; sets CSS and protects frame from overload damage

ASTM A27ASTM A27/27M Grade N-2
HardnessHB 170-210
ToughnessAKV ≥ 30J
Tensile Strength≥ 485 MPa
Yield Strength≥ 250 MPa
GradeCSiMn
ASTM A270.25-0.35≤0.60≤0.70

General-purpose carbon steel casting for thrust plates and non-wear structural parts
