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 strength, moisture content, capacity of …

In the Truck–Shovel system employed in open-pit mines, materials are moved from within the pit to external destinations, typically involving a crusher station for ore and a waste dump for discarded material.
Many of the general features indicated above are typical of large open-pit mining operations in North America. Mines commonly handle over 100000 t of ore and waste per day, moving the material through great horizontal and vertical distances. Transportation costs constitute a very high percentage of total mining costs.
