The measurement takes spot through the rotation of the bulk product Along with the shear mobile with the described pace. The looking at with the torsional resistances of the bulk content are taken in a very stationary lid employing a calibrated torsion sensor. For calculations that outline the circulation residence with the bulk substance, the size with the shear mobile lid (Fig. four), the cell rotation pace (1 mm s−one) and the normal load acting on the bulk content are taken into consideration. To evaluate the AIFE, a predefined regular stream index test was employed. The maximum usual load was decided on to become 10,000 Pa.
