Igneous rocks are basically used in flooring, landscaping and construction projects. However, igneous rock uses are specific to its type, which is classified according to the formation process, mineral content, hardness, texture and other properties.

Global energy consumption due to friction and wear in the …

The following conclusions were reached: • Total energy consumption of global mining activities, including both mineral and rock mining, is estimated to be 6.2% of the total global energy consumption. About 40% of the consumed energy in mineral mining (equalling to 4.6 EJ annually on global scale) is used for overcoming friction. In addition ...

Assessing the energy efficiency of a jaw crusher

 · Abstract. It is well known and taken for granted that the efficiency of energy use by comminution (i.e. breaking, crushing, grinding) equipment is very low, typically less than 10%. Most of the process input power is dissipated as heat and noise and ineffective deformation of the material to be processed and the device itself.

Energy Consumption in Crushing and Milling Process | …

 · Posted on December 5, 2012 by wujenifer315. Standard.
