A second factor causing this is the static charge respectively adhesive powers of fine particles. Also heterogenic materials– with elements of varying hardness – tend to stick, like for example plant samples or leaves where the thin leaves are ground fast to a fine powder but the harder / tougher stems remain coarse, but the fine leave
