Jaw Crusher an overview | ScienceDirect Topics
Rose and English [9] determined the capacity of a jaw crusher by considering the time taken and the distance travelled by the particles between the two plates after being subjected to repeat crushing forces between the jaws Therefore, dry particles wedged between level A and level B (Figure 44) would leave the crusher at the next reverse2014年9月1日· The main reason for this inefficiency is in the random distribution of forces on the particles inside the crusher With certain simplifications, the theoretical energy efficiency of comminution can be estimated to fall between 5 and 10 % (Legendre & Zevenhoven, 2014) while the measured energy efficiency in actual comminution testingAssessing the energy efficiency of a jaw crusher ScienceDirect
