Sieve analyses were performed after every five shots. It was found that the behaviors of the …
Size Reduction, the Three Laws of Comminution, and the Bond Equation
K VR is a constant associated with the resistance of the material to comminution. The second comminution theory is due to Kick, who suggested that the energy required is proportional to the reduction in volume of the particles. Substituting n = 1 in the general equation and carrying out the integration gives one form of the Kick equation,
Heterarchical modelling of comminution for rotary mills: …
Rotary mills aim to effectively reduce the size of particles through a process called comminution. Modelling comminution in rotary mills is a challenging task due to substantial material deformation and the intricate interplay of particle kinematics of segregation, mixing, crushing, and abrasion. Existing particle-based simulations tend to provide predictions that …
