The slurry-particle flow affects the dynamics and grinding efficiency in SAG mills, and ultimately impacts their performance, life span, and power draw. Numerical modeling can be used to gain insight and optimize the equipment design. However, including the geometrical details and the complex fluid-solid interactions in SAG mills is a challenging task.
This webinar presents an approach using the recently released fully coupled embedded SPH (Smoothed Particle Hydrodynamic) and Discrete Element Method (DEM) in Rocky 22R2 that can be efficiently applied to accurately capture both particle and fluid dynamics in particle-laden flows including SAG mills.
SPH provides a particle-based method to model complex free-surface flows with good accuracy, and its explicit formulation makes it suitable for massive parallelization on GPU-accelerated solvers.
Join us to understand more about this coupled approach and its application in modeling SAG mills. The simulation can be used to assess the influence of the operating conditions as well as the equipment design parameters on the charge dynamics, flow characteristics, and discharge behavior. The simulation approach provides valuable insight into how to improve the mill throughput, life span, and energy usage.
The webinar is designed to answer the following questions:
- What are SAG mills and how do they operate?
- What are the challenges when simulating slurry flows?
- How does Rocky SPH-DEM capture the slurry-particle flow inside grinding and SAG mills?
- Can Rocky SPH-DEM solve a 1:1 scale grate discharge problem? What does it take?
