The measurement requires position throughout the rotation on the bulk product Together with the shear cell at the described speed. The reading with the torsional resistances in the bulk material are taken in a very stationary lid using a calibrated torsion sensor. For calculations that define the stream home with the bulk content, the size of your shear mobile lid (Fig. 4), the cell rotation pace (1 mm s−one) and the traditional load performing to the bulk materials are taken into account. To evaluate the AIFE, a predefined common circulation index take a look at was used. The utmost typical load was decided on for being ten,000 Pa.
