Jan Stránský proposed the following answer:
Hello,
take care of error and warnings. I got

WARN  /build/yade-KKgSmd/yade-1.20.0/pkg/dem/SpherePack.cpp:211 makeCloud: Exceeded 1000 tries to insert non-overlapping sphere to packing. Only 231 spheres were added, although you requested 400.
WARN  /build/yade-KKgSmd/yade-1.20.0/pkg/dem/SpherePack.cpp:211 makeCloud: Exceeded 1000 tries to insert non-overlapping sphere to packing. Only 0 spheres were added, although you requested 600.

i.e. if you want to use this number of particles of this size, you need bigger area to cover (defined by minc,maxc a therefore dim value). In your case, all volume is filled by the first makeCloud and there is no space left for the other makeCloud
I used dim=9e-1 with nice results.

cheers
Jan
