Using SHELL Elements in ANSYS Mechanical Thin-walled structures are extensively used throughout many industries, because they can exhibit a high load-carrying per weight capacity. Aircraft, automobiles, storage vessels, and industrial buildings are just a few examples of the type of structures that extensively employ thin-walled construction.
stirred media mills and high-pressure grinding rolls, ball mills still retain a significant part of their importance in grinding, being widely used from minerals and cement, to chemicals and ceramics.
LEAP will be in Melbourne at the 2nd Int'l Symposium on Computational Particle Technology to showcase exciting new modelling work that has been completed recently using Rocky DEM and ANSYS CFD to predict liner wear in a semi-autonomous grinding (SAG) mill, using ANSYS CFD to model the effects of slurry flow within the mill on liner wear and ...
