In-Pit Crushing and Conveying (IPCC) systems are categorized into three primary configurations based on the mobility of their crushing stations and conveying systems, tailored for diverse mining scenarios (TAKRAF, n.d.).
Fully Mobile Systems feature crawler-mounted crushing stations, fed directly by shovels or excavators, largely eliminating primary truck haulage. These crushers move with the mining face, connecting to the main conveyor via mobile belt wagons or link conveyors (Oberrauner & Turnbull, 2024).
They offer the greatest operational cost reduction, with throughput potential less than 10,000 t/h (MCI Austria, n.d.).
Semi-Mobile Systems locate crusher stations near the working face, using small truck fleets to shuttle material. These movable crushers are periodically relocated (e.g., every 1-10 years) to maintain proximity (Oberrauner & Turnbull, 2024).
They balance mobility and stability, with throughput potential less than 12,000 t/h (MCI Austria, n.d.).
Fixed Systems have crusher stations permanently anchored within or near the pit, often requiring trucks for material transport. This in-pit placement significantly reduces haulage distances, maximizing cost savings (Carmaky, 2024). They are ideal for large, long-life mines with consistent, high throughput, typically less than 12,000 t/h (MCI Austria, n.d.).
