In this contribution the model and the real bulk rod- and needle-like materials, wherein one dimension is significantly higher than the other two, are rheologically tested. Standardization was
carried on a vibratory shaker. The breakable stirrer was assessed for measuring the stability, which represents the points of energy required to pass the stirrer through the bulk material. The compression curves are accompanied by granulometric curves, from which can be deduced, when the loose materials begin to break.
