The physicochemical properties of pea dietary fiber were improved by ultrafine grinding technology. Because of this, the application of pea dietary fiber in the field of hypoglycemic had a better effect, laying a foundation for the next research on hypoglycemic mechanism.
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 ...
With a reduced particle size, the solubility of ultrafine powders increased significantly (P < 0.05), whereas the water holding and swelling capacities decreased with a reduced particle size and then increased. Fourier transform infrared spectroscopy analysis showed that ultrafine grinding did not damage the main cellular structure of GS powder.
This modern ultrafine grinder has large output, low noise, convenient cleaning, sturdiness and durability. It is in line with the current trend of ultrafine grinding of materials and has become the new darling of current fashion. The ultra-fine grinder is especially suitable for ultra-fine grnding of dry materials and hard materials.

Notes on the Use of Ultrafine Grinder. For the use of ultrafine grinder, it is very common now, not only mining industry, industry, many scientific research, high-precision industries also use this mill. Although this model is widely used, many industries have not fully played its advantages and functions in the use.
Effects of UV-C light exposure and Ultrafine-grinding on the biotransformation from ergosterol to vitamin D2, physiochemical properties, and antioxidant profiles of mushroom shiitake and Jew's ear. Food Chemistry, 2019, 309, 125738. (IF: 5.399)
The mills traditionally used for wet ultra-fine grinding are high-speed stirred ball mills. The aim of the research was to investigate the influence of the solid (limestone) concentration and of the concentration of sodium polyacrylate on the apparent viscosity and the grinding efficiency. With increasing solid concentration the energy ...
High-speed stirred mills are utilized to grind particles below 10mm. Grinding sulphide minerals to as low as 10mm achieve adequate mineral liberation for successful downstream mineral processing operations, such as flotation and leaching. Particle breakage mechanism such as fracture or abrasion, determines the morphological surface features of the product particles.
The main objective of this research was to study the effects of ultrafine grinding and pulsed magnetic field (PMF) treatment on free gossypol (FG) content in cottonseed meal (CSM). The results revealed that FG content decreased from 831 to 584 mg kg−1 after CSM was ultrafine ground with an airflow crusher. A further decrease of FG content was achieved by processing with PMF. Response …

These results are inconsistent with some research conclusions that powder from ultrafine grinding often has a narrow particle size distribution (Zhao et al. 2009; Zhang et al. 2005). This occurs because the surface area of the powder increases with decrease in particle size (Zhao et al. 2013 ) and causes the powders to become active.
