Abstract The generation of grinding media wear during wet stirred media milling of organic particles was studied in dependence of product formulation parameters. It was shown that targeted product formulation leads to the reduction of ceramic grinding media wear for a certain product quality. Solids concentration and agglomerate size of product particles were identified as key parameters. Both influence the effective stress intensity of grinding media which has a significant impact on the generation of grinding media wear. Moreover, the reduction of grinding media wear can be attributed to the damping properties of comparatively soft organic particles. Their potential to protect ceramic grinding media from abrasion can be increased by tailoring formulation properties. Therefore, especially the increase of solids concentration was identified as most practical formulation variable which affects also grinding efficiency and production capacity.
