Particles in a conveyor

[d4rk3lf]

Thanks,

How about the sequential fractures, I tried to explain 1 > 2 > 4 > 8 > 16 > 32. When the original particle is fractured to about 16 fragments, the fragments should be deleted by their size. It would be nice to see the particle being gradually fractured in the process before deletion of the particle.

This would be a simple way to create dissolving particles in the liquid.

Set only 2 points for Voronoi, and change timing from "on event entry" to "continuous". 
That way you will fracture particles each frame by double... like you said... 1,2,4,8,16... etc. 
You can also extend this to 2 or more frames of you want to... just set every nth frame to 2 or larger number. 

Also, continuous will do fracturing each frame... if you need specific frame, or particle age, you can also set it up in timing parameters. 

Here I quickly created you example, with small particles being deleted.
