Based on Eq., the trajectory of a single grain during UAG is a 3D sinusoidal curve (as shown in Fig. 2). The effect of changes in abrasive grain trajectories on the grinding process is further illustrated in Fig. 3; compared to CG, interactions and overlapping of tIn theory, it is possible to control both the interactions and overlapping through defined abrasive grains distribution.

The present study explored the effect of size reduction by superfine grinding on the performance and rheological properties of bran-enriched dough. Coarse ( D 50 = 328.98 μm) and superfine-ground ( D 50 = 50.76 and 28.37 μm) wheat brans were incorporated into the wheat dough to replace 10–30% of plain flour.

K. Murugesh Babu, in Silk (Second Edition), 2019. 8.13.9 Antistatic finish. The static-charge build-up on silk is only moderate, but when silk is grafted with monomers to modify certain properties the problem of static charge increases. The static charge of styrene-grafted silk increases with an increase in styrene content; the increase being nominal up to 40% styrene build-up but rapid beyond ...
