The comparison is conducted using a rigorous cement mill circuit simulator used for operator training. The simulations reveal that compared to normal MPC, soft MPC regulate cement mill circuits better and in a plant friendly way by using less variations in the manipulated variables (MVs).

The first objective when modernizing a grinding circuit by installing a high efficiency classifier is to increase the mill efficiency, with a consequent increase in mill through-put. Reduction of the bypass is the main means of boost-ing the mill throughput when the modernization con- sists of replacing a classifier of an older generation. The

Posts: 1. Topic starter 01/03/2020 9:09 pm. Hello, our open mill circuit has three chambers having capacity 250 mt per day. we want to know how much area of it should remain empty for suitable grinding/ output. Regards,

The three-compartment open circuit cement ball mill was modelled by the perfect mixing approach. • Mill diaphragms were modelled by the efficiency curve model. • The three-compartment ball mill was simulated as a two-compartment. • Capacity of the three-compartment ball mill was increased by 10%.
