Retired，and frequent breakdown

3 times lifespan and in-situ operation
Wet parts slightly weared

Primary ball mill slurry pumps face exceptionally high failure rates due to the presence of coarse ore particles and occasional mill ball fragments, which cause rapid wear and frequent breakdowns

BOCO UltraSiC slurry pump has demonstrated exceptional performance in addressing the extreme operational challenges of primary ball mill slurry pumping, Failure Free

Conclusions

BOCO UltraSiC ceramic slurry pump has demonstrated exceptional performance in addressing the extreme operational challenges of primary ball mill slurry pumping, Failure Free

Note: Service life may vary depending on specific site conditions.

Particles on Site

Due to poor management, the filter grid became excessively worn, resulting in failure of the filtration function and allowing large ore particles or alloy ball fragments to enter the slurry.

Normally the large particles in slurry are iron ore, and would be uniform in size.

Chrome Ball Fragements in solids

Oversized particles can cause severe impact wear on pump flow components, and may even lead to direct fracture

Filter grille in poor condition

Due to poor management, the filter grid became excessively worn, resulting in failure of the filtration function and allowing large ore particles or alloy ball fragments to enter the slurry.

Normally the Large Ore Particles

Status After 3 times Lifespan

Wet parts of the Boco ceramic slurry pump showed only minor wear during preventive disassembly inspection at the 3x lifespan mark‌, fully demonstrating its excellent wear resistance and impact resistance. This indicates that the pump can maintain outstanding structural stability under long-term high-load operation, suitable for continuous operation in harsh conditions, significantly reducing maintenance frequency and operational costs.
