Molecules Free Full-Text Effects of Airflow Ultrafine-Grinding
Five different ultrafine milled flours (UMFs) were prepared from Tartary buckwheat via airflow ultrafine-grinding at different grinding pressures. The airflow ultrafine-grinding resulted in marked differences in particle size (from 100 to 10 μm). The UMFs were all brighter in appearance (higher L*) than Tartary buckwheat common flour

Study on micro-energy consumption model of ultrafine grinding
Ultrafine grinding Energy consumption model Fractal dimension 1. Introduction To obtain low-ash coal by physical or chemical methods, we process coal samples into ultrafine coal particles [1], [2], [3]. Ultrafine particles refer to particles with a size less than 30 μm, and some literature stipulates a particle size below 10 μm [4].
