A vibration mill, called a “tandem-ring mill”, which has cog-ring media in place of the ball medium of a conventional vibration mill, was developed to achieve high-impact pulverization of lignocellulosic biomass for bio-ethanol production. This study investigated pulverization...

A vibration mill using cog-ring media, called a “tandem-ring mill”, was developed to achieve high-impact pulverization of lignocellulosic biomass for producing bio-ethanol. Instead of the ball medium in a conventional vibration mill, it has a cog-ring medium. Japanese cedar powder pulverized...
