Ultrafine grinding is another method used to decrease grain flour particle size, while jet milling is an important alternative to the ultrafine grinding technique that is used to significantly reduce the flour particle size. Jet milling is a fluid energy impact-milling process that produces small particles (<10 μm) with a large surface area ...
Ultrafine grinding process is accompanied by high energy consumption and severe abrasion of devices. In addition, when particles are excessively small, they will become coarser rather than finer through agglomeration if we continue to grind, resulting in "negative grinding." During the ultrafine grinding process, changes will take place in ...
