Particles in a conveyor

[JuhaHo]

I'm starting to get some results.

There is two things, I need to fix for next simulation

1. Particles on the conveyor are penetrating each others, so I guess I need to add particle physics operator.
   
2. I modeled this thing based on 2D-drawings. There is a chute under the conveyor end. However particles are not flying long enough to hit the chute. Instead they are falling between the chute and conveyor. I'm thinking to build invisible chute to gap. However more realistic would be if the particles had inertial energy enough to land into the chute. Do I need particle physics to third event as well to do that?
