Potential hazards from dust explosion expand to most of powder processing industry with industrial development. The violence of dust explosion is the character of the sequence of dust explosion, the important parameter for risk evaluation, and the base for design and selection of various protection technologies. However, the discrepancies of violence exist for different instrument. The systematic comparison and analysis of the violence of dust explosion with the "20 litre sphere" and with "1.2 litre Hartmann tube" were conducted in this article.
