Abstract: The movement of large grid type ball mill is analyzed in Baosteel Concentrator.The different speed were established under transient model,analyzed their forces,hope to get useful conclusions.Because the actual production capacity has exceeds the original design ability,the ball mill's original parameters are no longer fit new production task demands.Through the analysis to find the favorable data improving production efficiency.

Key words: Ball mill, Finite element, Barrel, Static strength
