Reliable and effective grinding technology for diverse applications With more than 100 years of experience in developing this technology Outotec has designed manufactured and installed over 8 000 ball and pebble mills all over the world for a wide range of applications
Get PriceGrinding elements in ball mills travel at different velocities Therefore collision force direction and kinetic energy between two or more elements vary greatly within the ball charge Frictional wear or rubbing forces act on the particles as well as collision energy These forces are derived from the rotational motion of the balls and the movement of particles within the mill and contact
Get PriceThe mill was filled to various levels with mm 3/4 in ceramic balls as grinding media As feed material grindable limestone or mm 1/8 in nongrinding ceramic balls were fed at various steady state rates to determine the incipient overload conditions The prediction of overload has apparently been reduced to predicting the feed rate that results in 50% mill filling
