Particles pile up

[bdg]

Hello, i made an animation, there is a bin with 800.000 particles and a blending arm. This arm is rotating inside this bin. 

Now i there is a problem, the particles are pile up at the side wall and stuck at the blending arm. At the wall it looks in a uniform pattern and its not looking real.

I set the friction to 0%, and tried other values.

I have the same issue. It's like there's no physics at all.

I was told earlier not to use PhysX, but Particle Physic instead.
