We conducted three experiments to determine effect of particle size, mill type, and added fat on flow characteristics of ground corn In Experiment 1, corn was ground with either a hammer mill or a roller mill to produce six samples with different particle siz.
ادامه مطلبHow the mill achieves uniform particle size To achieve a uniform final particle size with minimal fines, the roller mill must have the right roll surface, roll speed ratio, and roll gap for your application. Roll surface. Typically, the roll surface is corrugated rather than smooth to achieve efficient size reduction, as shown in Figure 3.
ادامه مطلبThe size of the beads required for milling particles is 10 to 30 times the maximum particle size of the raw material and 1,000 to 3,000 times the mean particle size after milling. For example, when grinding calcium carbonate of 10 μm as the largest size of raw material to final-size particles of 100 nm, it is recommended to use 0.1 mm beads.
