Rice mill, which generally consists of a stationary hopper and drum, a rotating spiral conveyor and shaft running along the axis of the drum, is one of the typical stirred mills and has been extensively used for rice milling in food processing [1,2].Rice milling is to remove the external bran, meanwhile it can cause unexpected breakage, under-milled rice …
Read OnThe biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...

Read OnAncient Roman mills used in mining Roman mines used stamp mills which crushed the extracted ore before further processing. Stamp mills consisted of trip-hammers, powered by waterwheels through a system of cams. Stamp mills crushed metal ores down to small sizes in order to be smelted noting that they were also used in agriculture to pound grain.
