Dec , during the last decade, semifinishgrinding plants have been used more and more for the energy efficient grinding of highquality cement in , it was found that by decreasing the ball charge filling ratio it was possible to lower the specific energy demand for grinding significantlyOptimization of continuous ball mills used for finish,,The L/D ratio of the ball mill was varied in four steps of 1.75, 2.1, 2.79 and 3.49, and the ball charge filling ratio was varied in three steps of 15%, 20% and 25%. The experiments clearly indicated that the optimal L/D ratio and the optimal ball charge filling ratio are different for each feed fineness.Optimization of continuous ball mills used for finish,,10/12/2004· The optimal L/D ratio range is quite broad again with the minimum in the range of 3.2. For one compartment mills, this optimum should be less due to the lack of the first compartment used for coarse grinding. The optimal ball charge filling ratio for Combi-ball mills is supposed to be less too.Cement Ball Mill Optimization - krosline,Ball mills optimization ball mills account for the majority of all mills in cement plants and therefore the optimization of established ball mills implies high savings potentials parameters that hold potential energy savings are load level, revolution speed, combination of the ball charge, lining design and the adjustments of the separator standard optimization.Cement grinding optimisation | Request PDF,The energy efficiency of ball mills for use in finish grinding is relatively low, consuming up to 30-42 kWh/ton clinker depending on the fineness of the cement (Cembureau, 1997;Marchal, 1997).Ball charges calculators - thecementgrindingoffice,- Ball top size (bond formula): calculation of the top size grinding media (balls or cylpebs):-Modification of the Ball Charge: This calculator analyses the granulometry of the material inside the mill and proposes a modification of the ball charge in order to improve the mill efficiency:
