Quantifying the effect of the grinding aids in a batch stirred mill by a modelling approach

Grinding aids are commonly used in dry grinding to disperse the material in the system effectively and to improve grinding performance. Most of the time, different grinding aids with varying dosages are tested in laboratory conditions by trial and error. A simple methodology is required to compare the results of different grinding aids and dosages in batch milling. In this study, the utilization of the modelling approach in comparing the effect of grinding aid types and dosages were aimed. In order to achieve this, an experimental program has been conducted using a laboratory-scale batch stirred ball mill. The empirical model developed using the Farazdaghi-Harris model offers a new approach to determine the effect of grinding aids on grinding performance. © 2022 Union of Chambers of Engineers and Architects of Turkey.
