CASE STUDY
An oversize ore blockage in the ROM (Run of mine) bin or primary crusher can typically result in downtime of between 10 – 40 minutes, if being cleared using a rock breaker. This can take significantly longer for larger rocks or instances that require manual intervention. Downtime from oversize ore blockages accounted for 4% of lost production throughout the year for a primary crusher on an iron ore mine site. The site’s capacity was 20 mtpa and ore blockages resulted in 800 ktpa of lost production. At an iron ore price of $150 per tonne, this amounted to production losses of approximately $120 million per year. The LoadWise system was demonstrated to reduce these blockages by up to 80%, and provide an increase in revenue of up to $96 million per year.
