 i want to use PSD

i want to create new spheres for it

>  it is really not clear what you want to do.
what i want to do is that:
first,create a clump such as :
     clump1=O.bodies.appendClumped([\
     sphere([0,0,1], material=Mat, radius=0.5),\
     sphere([0.2,0,1], material=Mat, radius=0.5)\
    ])
second,create a  binary sphere particles system contained both big and small particles,like that:
      sp=pack.SpherePack()
     sp.makeCloud((0.2,0.2,2),(2.4,2.4,18),psdSizes=[0.1,0.1,0.4,0.4],psdCumm=(0.0,0.8,0.8,1),seed=1,porosity=1)  
third, replace the big sphere particles by cerated clump,like that:
     for r,c in sp:
        if r>0.1:
              ....#replace the sphere by clump
