Abstract:

The mechanism of comminution with high pressure roller mills, which has great significance to the design and application of high pressure roller mills, is presented in this paper. The damage process of rock material bed under rolling is analyzed, and the stress and the damage morphology of particles are discussed. Then the specific work consumption of the rolling comminution of rocks is measured, and the four subpocesses in which the high pressure roller mills work are obtained.

Key words: Rolling comminution, Mechanism of comminution, Stress, Damage morphology
