Özet
Grinding aids are organic compounds that chemically attach to a sufficient amount of particle surfaces and prevent the formation of gravitational forces between particles. With the use of grinding aids in grinding, it is possible to increase the amount of production with the wanted product fineness and obtain a finer product with the identical amount of production. The usage of grinding aids prevents particle pelleting and leads to reduced energy consumption. The work aims to research the impacts of three pure grinding aids from different chemical classes on the dry grinding of calcite by the change in grinding time in a vertical stirred media mill. Concerning the results, this study has different aspects than many other studies. In the current study, the results were assessed with different findings: product particle size (d50), media coating, and energy consumption. Addition-ally, powder flowability and surface area were evaluated by different methods. The findings obtained from the experiments demonstrate that all grinding aids in small quantities remarkably had a positive effect on grinding performance of the ground products in comparison to grinding without additives. Moreover, a strong impact of certain grinding aids on the each findings were combined around summary a target diagram.
