Does this mean there is hope? Will any
of us be around to find out?
Good sleuthing! (But how do you know
"wheel mill" means KDS?)
excerpt:
"Japanese cider pin-chip was used as the pulverization feedstock, which was pulverized using a cutter mill and wheel mill in series (Steal Plantech Co. Ltd.)."
Conclusions
Laboratory-scale MTVM experiments were performed and the results were used to predict the fine powder production and energy consumption per unit yield for an up-scaled MTVM system. Since the fracture rate of woody biomass in a small pot is much faster than in bigger pots, MTVM limited the pot size and used numerous small pulverization tubes. Such a system showed high pulverization performance for fine powder production and reduced energy consumption per unit yield. The overall production of wood powder significantly increased in the scaled-up MTVM, and approximately 1.2 t/h of fine powder can be produced with a 1.1 m size pot. Since production rate increased with a scaled-up MTVM, the relative energy consumption for fine powder production could be reduced to 1 GJ/tproduct. In a stage grinding system for fine wood powder production, the total energy consumption was 1.48 GJ/t where 70% of this value was consumed for fine grinding using MTVM. This energy consumption was much lower than the conventional single tube pulverizer.
