Application of the proposed method in a 988m sag mill indicated that the liner wear profile along the liner length is non-uniform and the highest wear occurs between 1.
Qualitatively predicted liner evolution within a long-running ball mill using demMany efforts have been made to investigate liner wear within various comminution devices and to develop a methodology for accurately predicting liner wear in the comminution devices is one of the foci in this field.
As the ball wear rate depends directly on the surface of the media charge a small variation in power will lead to an important increase of wear rateThe risk of underloading or overloading the mill is an additional factorplan a liner change andor change mill speed if possible.
Ball mill liner is used to protect the cylinder so that the cylinder from the abrasive body and material direct impact and friction but also use different forms of the liner to adjust the movement of the grinding body state to enhance the grinding body of the material crushing effect help improve the grinding efficiency of the mill increase production reduce metal.

Dec 08 2009 re: how to estimate the wear rate for ball millMost practical way to by measuring empty height and calculating the volumetric filling of grinding mediaAlternative way to make track of mill main drive kw consumption reduction and add makeup charge according to the extent of fall in power consumption.
Four factors influencing the liner wear of a ball mill news date: 10:07:38Ball mill is one of the necessary part of grinding machineMany customer of ball mill complain that the liner plate of a ball mill is with short service life and a high production costs.
How to calculate size of ball mill in cement plantA total apparent volumetric charge filling including balls and excess slurry on top of the ball charge plus the interstitial voids in between the balls expressed as a percentage of the net internal mill volume inside liners b overflow discharge mills operating at low ball fillings slurry may accumulate on top of the ball charge causing the.
In a ball mill the rate of wear of the liner is difficult to determine and can vary greatly according to such factors as the type and amount of the charge and the percent of solids therein the size density hardness and quantity of mill balls and the rate of revolution of the ball-mill container.
In some certain working conditions rubber liners can substitute metal liners and achieves better benefit.
The sag mill liner wear is subjected to the zero order kinetics modelThe comparison of the measured and modeled data of liner thickness it was found that the proposed model could get a good fit to measured dataThe new model was proposed to make possible the sag mill liner wear prediction at any given operating time.
Jan 07 2015 large balls are directed towards the inlet end with the ball dimension decreasing regularly from the inlet towards the outlet where smaller balls are located1 surface shape of mill liner: the most frequent phenomenon of wear of mill liners is the formation of grooves.
Liner and grinding medium of ball millLiners and grinding media are important components of ball mills or indispensable for work they are easy to wear and consume a lot.
Liners protect the outer shell of the mill from wear - liners are renewableLifters prevent slipping between the medium and slurry charge in the mill and the mill shell14 d is the diameter inside the mill liners and le is the effective length of the mill including the conicalSteel balls in a ball mill or large.
