Effective role of grinding aids in the dry grinding performance of calcite
2023/8/1 The inefficiency of grinding, especially in dry grinding, is generally explained by the slowing effect caused by fine particles. This may originate from the particle regrowth or rebuilding from smaller particles as a result of either agglomeration, including van der Waal's forces, or direct briquetting, or ball coating in order to provide soft surfaces [1,7,16,17].
