Industrial Vertical Stirred Mills Screw Liner Wear Profile
apr 10, 2021 several approaches for vertical stirred mills modeling can be found in literature, among which stand out the mechanistic approach, discrete element method empirical models, and nally, the population balance model however, the un-derstanding of the screw liner wear is not well developed yet.may 15, 2018 the motion of beads in a wet mill using discrete element method has been reported 10. they simulated the bead motion for a short period of simulation and assumed a set of beads as one particle. yamada and sakai coupled the dem for the solid phase and the moving particle semi-implicit method for the fluid phase even though emphasis in recent years has been on the use of computationally intensive modeling and simulation methods such as the discrete element method and computational fluid dynamics however, due to the computational requirements of these two methods, initiating a study that spans the stirred mill design space would take a lot of jul 25, 2016 discrete element method simulations of a 5-scale laboratory ball mill are presented in this paper to study the influence of the contact parameters on the charge motion and the power draw. the position density limit is introduced as an efficient mathematical tool to describe and to compare the macroscopic charge motion in different scenarios, i.a. with different values of the contact parameters.
