In open-pit mines, the traditional truck-based haulage system has consumed large amounts of energy in the haulage sector for many years. The use of continuous in-pit crushing and conveying (IPCC) systems is a viable option to significantly reduce energy consumption in this sector.

A jaw crusher usually wears more manganese steel per crushed tonne than a gyratory crusher. Feeding fines into the crusher may increase peak stress loads because of packing ? ie material being compacted as far as it compacts. This is enhanced by moisture, which again is highest in the fines and quite common in underground mines.

Mining of raw materials is a process that consists of several stages. In open-pit mining, material with high compressive strength is extracted by drilling and blasting and material with low compressive strength is extracted by e. g. a bucket wheel excavator. Most important influencing factors for crusher decision are compressive …

In-pit crushing and conveying (IPCC) is getting popular in deeper open pit mines as a suitable alternative to truck haulage because it offers a lower operating cost due to shorter haulage distance and less truck requirement. Semi-mobile in-pit crusher, currently the most popular IPCC system, is relocated every two to five years, and the …

The remaining deposits are located at depth, with no easy access, which requires high initial capital costs (Osanloo, 2012). Mining at great depths and high tonnages is possible only through open pit mining. Today, more than 80% of open pit mines in the world use a shovel-truck system for loading-hauling operations (Osanloo, …

Open-pit mining at the Palabora mine. Throughout its 35-year life, Palabora was often at the forefront of surface mining technology developments. A key feature was its use of a trolley-assist system for haul trucks coming out of the pit, to save diesel, and it was one of the early users of both in-pit crushing and computerised truck …
