Downloadable The grinding process of the ball mill is an essential operation in metallurgical concentration plants. Generally the model of the process is established as a multivariable system characterized with strong coupling and time delay. In previous research a two-input-two-output model was applied to describe the system in which some key indicators of the process were ignored.

Vertical roller mill application Control challenges Among the operational challenges of a vertical roller mill are the fast dynamics of the process. Compared to ball mills with dynamics changing in 15-20 minutes vertical roller mills have dynamics changing in 2-4 minutes. The fast dynamics necessitate even closer attention to LOI.
Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills dry basis is typically 75 vol.- ore and 25 steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
