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 (TBCF). Illustrated by the example of 70 °C, the UMFs were ...

Solid state joints of samples of coarse-grained (CG) and ultrafine-grained (UFG) nickel have been obtained for the first time using spot ultrasonic welding (USW). The UFG structure in disk-shaped samples was processed by means of high-pressure torsion (HPT). On the basis of lap shear tests, the optimal values of the clamping force resulting in the highest values of the joint strength are ...

The ultrafine grinding experiment was conducted using a supersonic steam-jet crusher (JSM-Q, Fig. 1) employing a separate grinding mode. The BFS, DG, and FA were directly ground into separate ultrafine powders. The SS was broken into particles < 5 mm before it was ground. Prior to the grinding, the steam in the machine was heated to 300℃.

During grinding activities, however, peak concentrations of 32 × 10 3 to 500 × 10 3 cm −3 were measured. At Grinding 5 in Plant E, a higher percentage of the particles were ultrafine (95%) and a higher concentration (64 × 10 3 cm −3) was found compared to the other grinding activities. This may be a result of continuous grinding during ...
