We performed numerical simulations of the impact of a bead on a rotating vane. Considering different realistic contact laws at the collision chosen from experiments, we define a typical trajectory as a bouncing regime followed by a sticking regime. We show that there exists a critical friction coefficient between the particle and the wall for which the particle rolls without any significative sliding in a second phase. We deduce that the friction of the grains with the vane may have a minor effect because the bead rolls without any sliding after a transient stage. This may have important outcomes in spreading applications.
