Web21 nov. 2024 · Comminution of bio-fibers is necessary for their effective application in development of reinforced composite and feedstock; however, comminution is an energy intensive process and minimization of specific energy required in the size reduction of bio-fibers is an optimization task in design of various particulate based materials. WebK is a constant. 2) KICK’S LAW States that the work required is proportional to the reduction in volume of the particles concerned. Where f is the diameter of the feed particles and p the diameter of the product particles, the reduction ratio R = f p according to Kick’s law, the energy required for comminution is proportional to log R/log 2. Energy E = log R log 2 … jim carrey im gay in living color
