Assessing the energy efficiency of a jaw crusher
As the rock comminution and energy efficiency can be defined as a function of area increment of particles in jaw crusher [41], the production of fines can be diminished by regulating the mf in the crushing chamber. From this point of view, feed level sensors or circuit breaker plugs may be beneficial for the regulation of mf during jaw crushing.
