Abstract
To reduce consumption energy during the pulverization process, pulverization pot of the vibration mill was modified. In this experiment, effect of the pot size and the number of tube in the pot on pulverization ability, such as pulverization particle size, crystallinity of cellulose, consumption energy and productivity, was evaluated. As a result, Consumption energy increase with increasing the number of the pot, but consumption energy per woody powder production in the multiple tube pot was improved significantly. Production speed of the multi-tube was almost as same as that single one, but the production amount increased the multiple number of this pots.
