The existing grinding balls had low hardness, high specific consumption, and high replenishment requirements, highlighting the need for a cost-effective, wear-resistant solution for hard-ore conditions.
Baseline Specific Consumption: 0.445 kg/t for 100 mm balls and 0.335 kg/t for 60 mm balls, resulting in high consumables costs.
①High Grinding Ball Consumption: Baseline specific consumption was 0.445 kg/t for 100 mm balls and 0.335 kg/t for 60 mm balls, driving up consumables costs.
②Low Hardness and High Wear: The existing balls had relatively low hardness, resulting in high wear and substantial monthly replenishment.
③High Operating Costs: Grinding ball procurement costs remained high at the same throughput, increasing overall grinding costs.
④Lack of a Cost-Effective Alternative: No suitable, cost-effective wear-resistant media solution was available for high-hardness ore conditions.
We achieve optimization through these methods
① Goldpro supplied high-hardness forged grinding balls with surface hardness ≥60 HRC and volumetric hardness 59 HRC, tailored for hard grinding conditions;
② Complete data comparison against Russian-made grinding balls under identical mill, ore, and parameter conditions to establish the optimal make-up ball charging regime;
③ On-site technical tracking recorded net running hours, hourly throughput, power consumption, and grinding ball wear to generate standardized test reports.
Full-Cycle Parallel Comparison with Local Supplier Products, Validated Through Comprehensive Industrial Trials.
Benchmarking under Identical Mill, Ore, and Operating Conditions, with Official Report Verification.
- Establishing the Ball Size Distribution, Charging Plan, and Monitoring BaselineInitial charge with 60, 80, and 100 mm balls; replenish with 100 mm balls in the first stage and 60 mm balls in the second. Monitor throughput, power consumption, total grinding ball consumption, and specific consumption per tonne of ore throughout the trial.
- Comparative Trial of High-Hardness Forged Grinding BallsGoldpro high-hardness forged grinding balls were evaluated against Russian-made balls under identical mill and operating conditions, with comprehensive data comparison throughout the trial.
- On-Site Monitoring and Trial ReportingRecorded net operating hours, throughput, power consumption, and grinding ball consumption throughout the trial, producing standardized trial data sheets and an official industrial trial report.
