Ball milling is a top-down technique that forms micro to nano-scale materials, by inducing heavy cyclic deformation. Currently, ball milling is widely used for the preparation of nanoparticles because of its simple operation, use of relatively inexpensive equipment and its broad applicability to most types of biomass [34]. Another advantage ...

Grain Husks Explained - Brew Your Own
Acting as mini-spacer in a mash, husks allow liquids to flow through a grain bed. Without any husks, the grains and their associated beta- glucans, which can be extremely gummy, will create a thick porridge-like mass in the mash tun. Without the "structure" provided by the husks, the grain bed is more like a ball of dough then a grain bed.
