OSORIO, Adriana M; MARIN, Juan M  e  RESTREPO, Gloria. Design and Energy Evaluation of two Grinding and Classifier Circuits of a Pilot Scale Cement Clinker. Inf. tecnol. [online]. 2013, vol.24, n.2, pp.99-108. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642013000200011.

The design and experimental evaluation of two grinding systems in closed circuit which use two types of classifiers, a pneumatic cyclone and a sieve vibratory, were carried out. The energetic efficiencies under similar conditions in material particle sizes at the mill entrance and keeping the same classifier were compared. The material was characterized by: X-ray fluorescence (XRF), surface area by the method Brunauer-Emmet-Teller and granulometry analysis by sieving. Results show that the mill speed does not have statistical significance over the grinding mechanical efficiency and using a response surface analysis was determined that the cyclone favors the milling (optimum value 30%) against the sieve vibratory type (optimum 18%). Models found for mechanical efficiency determination of the systems mill-cyclone and mill-sieve vibratory, show correlations of 85 % and 83%, respectively.
