HPGR Roller Presses

FLSmidth HPGR (High-Pressure Grinding Rolls) delivers energy-efficient comminution with up to 40% lower specific energy consumption than SAG milling. Operating at pressures up to 8 MPa, the HPGR creates interparticle crushing for consistent product size. The stud-lined roll surface forms an autogenous wear layer. Anranst supplies tungsten carbide studs and roll segments for HPGR maintenance.

Wear Parts

Roller tires, Cheek plates

Roller Stud / Peg (WC Insert)

Tungsten carbide studs embedded in roller surface; create autogenous wear layer by trapping pressed material between studs

WC-Co Cemented CarbideISO K20-K40 / YG11C-YG15C
HardnessHRA 86-90
Toughness≥ 1800 N·mm
Tensile Strength≥ 2000 MPa
Yield Strength—
GradeWCCoOther
WC-Co Cemented Carbide84-89%11-16%≤1%

Extreme hardness for HPGR roller studs and VSI rotor tips; 5-10x longer life than Cr26 in pure abrasion; requires careful installation to avoid thermal shock

Edge Plate / Cheek Plate (Side Liner)

Contains material at roller edges; prevents material bypass and edge wear; hardfacing overlay extends service life

Cr-Mo Alloy SteelASTM A217 WC6/WC9 / GB ZG15CrMo
HardnessHRC 42-52
ToughnessAKV ≥ 25J
Tensile Strength≥ 750 MPa
Yield Strength≥ 550 MPa
GradeCSiMnCrMoNi
Cr-Mo Alloy Steel0.15-0.250.30-0.600.50-0.801.00-1.500.45-0.65—

Good combination of hardness and toughness; ideal for SAG mill liners, grate bars and crusher frame liners under abrasive wear

Hardfacing Overlay (Cr-C)Cored wire overlay / WC + Cr-C composite
HardnessHRC 60-68 (overlay layer)
ToughnessAKV ≥ 30J (base metal)
Tensile Strength≥ 600 MPa (base)
Yield Strength≥ 350 MPa (base)
GradeCCrNbWFe
Hardfacing Overlay (Cr-C)3.0-5.520.0-35.04.0-8.00-10.0Balance

Weld overlay on cast steel base; can be re-welded 3-5 times for extended service life; cost-effective for VRM rollers and HPGR cheek plates

Stud / Pin Insert

Tungsten carbide studs embedded in HPGR roll surface for autogenous wear protection layer
