Thank you sincerely for your assistance.

I've come across recommendations on CFD forums suggesting that particle diameters should be less than 1/10th the size of the smallest mesh element. Could this guideline be a factor in my simulation, given that my particle diameter (3mm) exceeds my minimum mesh size (1mm)? Additionally, could the specific physical models I've chosen be contributing to the unexpectedly high particle velocities? Would switching from a stochastic collision model to a DEM  collision model potentially address the unexpectedly high particle velocities I'm observing?
