Agreed. As the particles come closer together at the bottom, they experience an increase mutual repulsion, that keeps them apart. This mutual repulsion can be seen as a kind of pressure, and as such will prevent more from moving toward the bottom, without some moving back toward the top. It is not unlike the atmosphere, where the air is more dense near the earth than higher up. But if it were not for the mutual repulsion of the particles, there would be no increase in "pressure" between the particles near the bottom, and the particles would continue settling until they are all on the bottom.
