Concave / Bowl Liner for GP100 Series Cone Crusher

The casting geometry (profile, flange OD, height) is IDENTICAL. The difference lies in the Locking Hardware Kit supplied with the liner. GP100 (Legacy): Uses Locking Wedges + Bolts (mechanical). GP100S (Current): Uses Hydraulic Clamp Ring segments/bolts. Ordering Tip: Always specify "GP100 Mechanical Lock Kit" or "GP100S Hydraulic Clamp Kit" when purchasing. The liner casting itself is universal.

C (Coarse): ~900–950 kg | M (Medium): ~800–850 kg | F (Fine): ~700–750 kg | EF (Extra Fine): ~650–700 kg. Fits standard 5t–10t overhead cranes common on NW portable plants.

The GP100 annular gap is moderate. You need 35 – 55 liters (9 – 15 gallons) of two-component epoxy backing (Metso KrushMore, ESCOBACK, Copps). Order a "GP100 Bowl Liner Backing Kit" (typically 2–3 x 25L pails). Ensure the adjustment ring seat is clean and dry before pouring.

Do not wait for wear-through. Parallel Zone Thickness < 20–25 mm (measured at thinnest point). CSS Drift > 3–4 mm wider than setting (loss of reduction control). Product Shape Degradation: Increased flakiness/elongation (loss of parallel zone). Throughput Drop > 10% (cavity profile worn to "hourglass"). Visual: Cracking at feed lip or severe pitting/gouging in upper chamber. GP Series liners often wear faster in the parallel zone than HP due to the steeper angle—inspect frequently.

Absolutely not. Zero interchangeability. HP Series: Parallel crushing zone, hydraulic lock bowl, different thread/flange pattern. GP Series: Steep cavity, constant stroke, mechanical/hydraulic clamp lock, different bolt circle & flange profile. Forcing fitment destroys the adjustment ring and frame instantly.

1) Oversized Feed / Slabby Rock: Exceeding max feed size (typically ~150-180mm for GP100 M/F) causes impact fatigue. Fix: Scalp screen / primary crusher CSS adjustment. 2) Insufficient Backing / Voids: Air pockets under the liner lip transfer shock to the casting. Fix: Vibrate backing during pour; verify 100% fill. 3) Loose Locking Hardware: Liner shifting under load. Fix: Re-torque wedges/clamps per schedule (2hrs/24hrs). 4) Wrong Metallurgy: Standard Mn18Cr2 on high-impact quartzite. Fix: Upgrade to Mn22Cr2 or TiC Composite.

Yes, Critical for GP100 (Mechanical Lock): Seat liner fully (verify 360° flange contact). Install all wedges/bolts hand tight. Torque in 3 passes (Star Pattern): 30% → 60% → 100% Spec (Typically M30/M36 10.9/12.9 bolts ~ 1,200–1,800 Nm). Re-torque after 2 hours operation (MANDATORY). Re-torque after 24 hours. For GP100S (Hydraulic Clamp): Follow Metso hydraulic pressure setting procedure (typically 150–200 bar) + mechanical lock bolt torque.
