The widest distance is known as the open side setting (OSS) and the narrowest, the closed side setting (CSS). These settings are important. The OSS is the largest distance between the concave and the mantle at the bottom of the crusher, so it determines the largest particle size of the outgoing product.

The first of the two configurations modeled is a fixed IPCC system. The fixed system's function is not very dissimilar to that of a traditional truck/shovel system, only that the crusher is fixed for the length of mine near the pit crest, which ferries crushed ore via conveyor to the mill. The other studied case is a. COST CALCULATION
