Mantle, bowl liner, feed plate, arm bushing and eccentric bushing — original wear parts for MACKORN NH/NS single-cylinder hydraulic cone crushers.
Customs data shows that in most markets the imported parts value is 2–6 times the machine value: Chile 6.3× ($294.9M vs $46.7M), Peru 4.7×, Australia $562.1M (the largest worldwide), Ghana 73×, Zambia 8×. A machine is a one-off order; a liner is recurring cash flow — once a crusher is running, liners are replaced every year for the next 5–10 years.

| Mantle | The moving cone surface — the primary wear part |
|---|---|
| Bowl Liner | The fixed cone surface, paired with the mantle |
| Feed Plate | Feed distribution, prevents segregation |
| Arm / Eccentric Bushing | Drive and support interfaces |
| Locking Nut / Clamping Ring | Fitting and change-out parts |
Manganese grade is selected against ore abrasiveness. For highly abrasive feeds such as basalt and diabase we recommend a higher manganese content or a thicker profile — trading a little chamber volume for liner life.
We assess wear uniformity across discrete sections of the crushing chamber (uniformity = 1 − σ/μ) and recommend a multi-gradient hardness design H_i = H_base × k^i. Record the measured thickness at each liner change and we can derive the actual wear curve of your machine, predicting change-out dates and avoiding unplanned downtime.
uniformity = 1 − σ/μ ·
H_i = H_base × k^i
Mantle, bowl liner and matching wear parts for the MACKORN NH series (NH200 to NH895, 9 models) and the NS high-speed series (NS200 to NS600, 4 models).
The cavity (EC/C/MC/M/F/EF and so on) follows from feed size, target product and crushing stage. Run your duty through our selection tool to get the recommended cavity, or send us your feed and product sieve analyses.
It varies widely with ore abrasiveness and operating conditions. Measure it: record the thickness difference at each section at every change-out and you get the actual wear rate of your machine (mm/1000h) — far more reliable than applying a rule of thumb.
Yes. Give us the model, cavity, annual consumption and maintenance intervals, and we will hold stock against your plan to shorten lead time.
