This paper presents the studies carried out to estimate the grinding energy of vertical roller mills via breakage test. An extensive laboratory and pilot scale test work was performed. In the first step, breakage characteristics of eight samples having different competence were determined by piston-die tests. Then, the samples were subjected to a size reduction process using a pilot scale vertical roller mill. Feed size, product size and energy data from pilot scale grinding tests were evaluated with material characterization tests. Based on energy-size reduction models proposed in the literature, equations were derived to estimate the grinding energy of the vertical roller mill by using the size and piston-die test data.

本文介绍了通过破碎试验估算立式辊磨机研磨能量的研究。进行了广泛的实验室和中试规模的测试工作。在第一步中，通过活塞模具测试确定了具有不同能力的八个样品的断裂特性。然后，使用中试规模的立式辊磨机对样品进行尺寸减小过程。来自中试规模研磨试验的进料尺寸、产品尺寸和能量数据通过材料特性测试进行评估。基于文献中提出的能量尺寸减小模型，通过使用尺寸和活塞模具测试数据推导出用于估计立式辊磨机的研磨能量的方程。
