Abstract: The proposed research paper analyses power consumption in grinding rolls of a flour mill. The observed mill has 15 grinding passages. The hourly efficiency of grinding roll on the first passage is 3,006.72 kg/h. The specific power consumption of individual grinding rolls ranges from 4.955 to 24.26 kWh/t. The thesis also contains results of research of grinding effects on grist. The greatest effect on grist was observed on the first grinding passage, where particle size after grinding was only 12% of the original grain size, as determined by sieve analysis. On the second through fifth passage, it was 85 to 96% (or 78 to 85% with shelling) of the original size. It was discovered during scouring that, in some cases, the sieve size of particles after grinding increased from 101 to 104% of the original size. This is due to shear force causing trituration of grist.
