Overlapping Parcels in DDPM-KTGF model in FLUENT

I am working with mixing of printing polymer and solid syntactic foam balloon particles in order to yield a uniform mixing of balloons within the polymer. I'm using fluent DDPM-KTGF model. But, on injecting particles the solid particle concentration near the inlet is very very high. Upon careful observation I noticed that multiple parcels were actually overlapping each other near the inlet that is why the volume fraction and the concentration was very high. 

Therefore, I am searching for a solution to counter the over lapping of particles that causes divergence, reverse flows etc. Any help would be appreciated.

Please check in the help "Staggering of Particles in Space and Time". That might be useful for you.
