oct 19, 2007 the motivation for this research was derived from the situation in ball mills at matimba power station in south africa, where the mill capacities drop substantially as liners wear down during mill operation. this finally leads to re-lining of the mills to restore their capacity, while the worn liners have only lost 1020% of their mass successful mill shutdown can be measured by timely completion and zero harm. removal and change out of worn liners and lifters as well as essential maintenance on existing mill lining is a job for a skilled professional team. It is well known that using a mill relining provider can save up to 40% of downtime for scheduled mill reline works.

ball mill liners for mineral beneficiation polycorp. polycorp ball mill liners provide long, low maintenance, service life. In addition to protecting and sealing the ball mills steel shell, the liner imparts motion into the ball charge. careful, intelligent, liner design can help to improve the operation and performance of grinding due to the nonuniform liner wear profile along sag mill the mill length the lifter angle face for any given operation hours varied significantly. for example, the largest change in the lifter typical 3-d model of a worn liner after 5384 of operation is angle face for the operation hours of
ball mill liner thickness measurement tools average wear rates in ball mill liners apartmanlipno to provide the key between the mill charge and the mill shell for charge motion to maximize the rate of delivery of thrown grinding media at the toe of the charge to gain the best milling action to avoid liner and. online chatlonger lasting mill liner means less downtime for maintenance or new liner installation. mill liner that occupies less space allows increased volume within the mill and leads to greater grinding capacity and throughput potential. safer maintenance. 50% lighter and have 50% fewer parts on average when compared to traditional cast steel liners.
uses of a ball mill liner the role of a ball mill liner is to give the mill heads protection against wear and tear thus increasing their lifetime and creating optimal grinding efficiency. the design of a ball mill liner depends on the drilling pattern of the mill heads, the rpm speed of the mill, the maximum grinding diameter of the media and the percentage of media filling.the application stores wear profiles and mill operating parameters, and analyses the wear and performance of the liners, he said. striking the right balanc As with most things in life, selecting the most appropriate liner for a specific milling operation can be a balancing act between longevity, cost and several other factors.
