Dynamic classifiers: These incorporate a rotating rotor and, consequently, have a wider operational range. High efficiency classifiers: These combine useful elements both of the above technologies by using a static set of vanes to guide the airflow into a rotating rotor, alongside other optional features.

The classifier was modelled in four blade lengths of 110.74 mm (original length used in industry), 212.34 mm, 313.94 mm and 415.54 mm. Moreover, at each modelled blade length, four opening angles of 40°, 50°, 75°, and 90° were set. Hence, 16 classifiers models for the developed classifier geometry were numerically performed for this research.
