Abstract
Recently, on-site recycling method used mobile crusher has been receiving considerable attention. As the function of the mobile crusher is to crush the concrete blocks and to use the fragments as the aggregates at the construction sites, the machine needs to have an ability to crush the concrete blocks to the target particle sizes. However, many parameters of the machine such as the discharge width and rotation number affect the crushing performance. So the effect of these parameters on the crushing performance is not cleared. In this paper, the simulation model by using Distinct Element Method (DEM) to predict the crushing performance of the mobile crusher was developed, and then the effect of several parameters on the crushing performance was analyzed by using Principal Component Analysis (PCA), which is one of multivariate analysis technique.
