Dec 10, 2019 · the cement ball mill in cement plant is usually divided into 2-4 silos, the most representative of which are the “new type of high fineness cement ball mill” and “open flow high fineness cement ball mill”. there are three cement processing circuits. 1. open circuit grinding the ball mill in the cement plant for open circuit grinding
Dec 08, 2009 · re: how to estimate the wear rate for ball mill. hey; ball wear can be measured by weighing an entire charge before and after grinding a known tonnage of materials. with new balls sample of given size can be weighed before and after grinding a given tonnage and, assuming uniform wear per unit of ball surface, the total charge wear can be estimated
Jan 07, 2015 · raw mills usually operate at 72-74% critical speed and cement mills at 74-76%. 3.2 calculation of the critical mill speed: g: weight of a grinding ball in kg. w: angular velocity of the mill tube in radial/second. w = 2*3.14*(n/60) di: inside mill diameter in meter (effective mill diameter). n: revolution per minute in rpm
Aug 02, 2013 · in grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a mineral processing engineer aka metallurgist to do. often, the ball used in ball mills is oversize “just in case”. well, this safety factor can cost you much in recovery and/or mill liner wear and tear
