time at the crusher is taken as 420 seconds (7 min­ utes) as is with the current set up, then the unit costs in May and December are $2.07per bcm and $2.21per bcm respectively. In this case only a saving of %7 ($0.14 per bcm) can be achieved with better fragmentation. Figure 7. Speed/time graph. The cost savings come from faster truck loading

Crushing of Ores and Rocks in Mineral Processing ...

Ore fragmentation in a crusher can be achieved by different mechanisms: Compression against a rigid surface; self-crushing (attrition) during the compression phase; by impacting against a rigid surface; by impacting matter on matter (autogenic). Depending on the crusher type, it could be combining several of these mechanisms. The crushing operation is usually carried out dry, but we use water ...
