What is the element Velocities after the collision when attachment occurs?

Hello everybody,
I have the number of particles in a Fluid (CFD-DEM). I used HM-JKR as a contact force and I saw a lot of agglomerates in the tube. I tried to see the X, Y, and Z elements of two particles' velocities after the collision by EDEMpy. I expect that after collision those particles which attach have the same velocity but when I compare the two vectors, I can't find equal numbers in 2 vectors. (for example Vx for element A and Vx for element . Could you please guide me on this issue?
The Excel file of the velocity vector has been attached.
