研究了湿式搅拌磨有机颗粒过程中研磨介质磨损的产生与产品配方参数的关系。结果表明，在一定的产品质量下，有针对性的产品配方可以减少陶瓷研磨介质的磨损。确定了产品颗粒的固体浓度和结块粒度为关键参数。两者都影响磨削介质的有效应力强度，对磨削介质磨损的产生有重要影响。此外，研磨介质磨损的减少可归因于相对柔软的有机颗粒的阻尼特性。它们保护陶瓷研磨介质免受磨损的潜力可以通过定制配方特性来增加。因此，确定固体浓度的增加是影响磨矿效率和生产能力的最实际的配方变量。
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.
