Particles in a conveyor

[JuhaHo]

Thanks,

I use particle Physics for Particle-Particle collisions. If I didn't have that Two things happens:
1. The particles are not piling up so the particles form a flat carpet
2. The will be tight particle concentrations, because the particles want to be in same place and don't know that's already crowded.

After the chute, there's liquid, where the particles eventually dissolve. I have multifracture operator to split particles gradually and size test operator to vanish small particles until there's only liquid there. I have liquid force to move particles along with liquid. The liquid is moving constantly.
