Crushing Efficiency Factors - Mineral Processing Metallurgy

Jul 12, 2016  The sum of the work for compression and shearing is the energy input. At the present state of the art the efficiency can only be compared to that of the associated energy of free crushing. Thus, if a lesser energy is required, a higher efficiency can be calculated over that for simple crushing.

Assessing the energy efficiency of a jaw crusher Semantic Scholar

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. Here, a study is reported that analyses the reasons for this low efficiency ...
