Mineral-to-Wear-Life Reference Chart

Beibangpu Field Data

Typical wear-part service life by mineral type, wet-end material and solids concentration. Data drawn from Beibangpu installed-base field records and industry engineering practice. Use this chart as a planning baseline for maintenance intervals and spare-parts budgeting.

Mineral / Duty	Typical Solids %	Recommended Material	Impeller Wear Life (hours)
Copper concentrate (rubber-compatible)	35 – 55%	Natural rubber	8,000 – 12,000
Copper tailings (coarser particles)	30 – 45%	A05 high-chrome	6,000 – 9,000
Iron ore tailings (hematite)	25 – 40%	A05 high-chrome	7,000 – 10,000
Iron ore mill discharge (magnetite)	40 – 65%	A49 high-chrome	5,000 – 8,000
Gold flotation feed (pH 8-10)	30 – 50%	Natural rubber	10,000 – 15,000
Gold tailings (coarser)	35 – 55%	A49 high-chrome	6,500 – 9,500
Coal washery fine discharge	20 – 35%	A05 high-chrome	5,500 – 8,000
Coal + abrasive sediment (coarser)	25 – 40%	A49 high-chrome	4,500 – 7,000
Phosphate slurry transfer	30 – 45%	A05 / natural rubber	6,000 – 9,000
Fly ash / bottom ash slurry	15 – 30%	A05 high-chrome	4,000 – 7,000
Incorrectly-sized ash pump (reference: coal plant, tip velocity >135 ft/sec)	25 – 30%	Any	300 – 500 ⚠ non-compliant

Engineering note: The difference between a 500-hour impeller life and a 10,000-hour impeller life is rarely a difference in pump brand — it is a difference in hydraulic sizing discipline (tip velocity compliance: 100 ft/sec max for ≥40% solids), wet-end material match (rubber for fine or corrosive; A05/A49 for coarse), and operating practice (avoiding prolonged cavitation and dry running). Wear life figures above assume compliant selection and operation.

Wear life ranges are field-derived estimates for typical mining duty on Beibangpu AH, AHR and MD series pumps with correctly matched wet-end material and compliant tip velocity. Actual service life varies with particle hardness, shape, operating cycle and maintenance practice.
