a decided advantage over a ball mill system. However, despite these benefits, applications of the vertical roller mill for cement grinding are less prevalent. The twocompartment ball mill operating in a closed circuit with a high efficiency separator is thus still the most preferred arrangement for new cement grinding

Then, various simulations examined the impacts of closedcircuit vs. opencircuit operation, number of compartments, and various ball size distributions. Our results suggest that integrating an air classifier into an opencircuit ball mill can increase the production rate by 15% or increase the cementspecific surface area by 13%.

Fullscale closedcircuit cement ball milling was modeled using a true unsteadystate simulator (TUSSIM), based on a transient cellbased population balance model (PBM) with a set of differential algebraic equations (DAEs). As a major novelty, the PBM for the mill was coupled with a dust loaddependent, variable Tromp curve for the air classifier.

Abstract. The characteristic differences between open and closedcircuit grinding systems were examined via the use of a continuous vibration ball mill and a blade type classifier. For the same median diameter of the product, the rate of powder production in the closedcircuit is about 5% higher than that of the opencircuit.
