Optimization of mill performance by using

of the procedure: grind-out, mill stoppage, mill start-up and the transition period to steady state. Stresses, generated in the ball charge, increase, which may result in spalling of balls and blocking the grate discharge. Optimization of mill performance by using online ball and pulp measurements by B. Clermont* and B. de Haas* Synopsis Ball mills are usually the largest consumers of energy

CHARGING GRINDING MEDIA - Grinding &

Prior to mill shutdowns, the operators should occasionally grind out the mill for a short period of time. This is simply stopping mill feed and observing power draw. The power draw should increase in this time to a consistent level. Ball charging should be increased or decreased depending on the observed power and results from actual charge level measurement.

the motion of grinding charge inside the mill. He also verified his approach with various plant data (Napier-Munn et. al., 1996). In this study, power draw of 14 multi-compartment cement grinding mills were calculated based on Morrell's approach. Design and operational parameters for the mills were collected from operating plants. With this respect, ball load within the mill which is the

Rod mill charges usually occupy about 45% of the internal volume of the mill. A closely packed charge of single sized rods will have a porosity of 9.3%. With a mixed charge of small and large diameter rods, the porosity of a static load

THE GRINDING CHARGE OF ROTARY MILLS

This paper presents the achievemens of grinding charge for the tube mills with balls.The author shows charactheristic size of grinding media charge: bulk density, porosity, filling degree. Regarding this last size,the author presents a way of its estimate,control and adjustment by measuring the level of charge. In the end,the way of establishing the material amount in the mill is presented,to
