A device for the removal of a liner bolt from a SAG mill including a support member for affixing to an exterior surface of the SAG mill and a ram affixed to the support member and having an end movable relative to the support member. The end serves for compressive abutment with a surface of a liner bolt. The support member includes a first arm, a second arm, and a strut connected …
Mill liners do not affect the stiffness of the shell, even for liners as large as the Cadia SAG mill liners. This is because the liners are discontinuous both axially and circumferentially. The mill liners can be modelled as distributed masses with no loss of accuracy in the resultant stresses.
SAG Mill Components Once the basic operating conditions have been defined for the mill designer then, and only then, can he begin taking into account shell and head stresses and trunnion bearing sizes required to carry the load and to give the required openings for feeding and discharging the mills.
Liners for the Grinders. Liners do much more than just protect a mill's shell, with current research aimed at optimizing liner design and cutting milling costs. By Simon Walker, European Editor. The introduction of rotating ball, tube and rod mills into mineral processing in the late 1800s was quickly followed by the realization that ...

The mill critical speed will be calculated based on the diameter (above) less twice this shell liner width. Mill Actual RPM: Enter the measured mill rotation in revolutions per minute. Result #1: This mill would need to spin at RPM to be at critical speed.
Don't you use a layer of rubber behind the liners to protect the shell? Here for steel liners in a SAG mill, 10 to 15 mm (1/2 inch). Here on primary mills the liners aren't in there long enough to need filling in the gaps and I can't imagine any filler material that …
An AG/SAG mill was commissioned at the Brunswick mine concentrator in October 1998. This paper discusses the original shell top hat liner design for the bi-directional AG/SAG mill, observed liner wear, subsequent liner design modifications, and benefits. The original liners were steel chrome-moly steel Norsteel with rubber grates and rubber ...
Stopping mill equipment is not a desirable alternative, so the best way to resolve SAG mill challenges is to use simulation technologyfor equipment design alterations. Replacing the SAG's worn-out liner can occur every six to nine months and cost between $30,000 U.S. and $200,000 U.S. per hour, and each repair takes between 40 hours and 120 hours.
SAG/AG mills: • Integrated and/or plate and lifter designs for head and shell liners • Grates • Pulp lifters • Filler rings Ball mills: • Single wave liners • Modified single wave liners • Double wave liners • Shell liners • Feed head liners • Discharge end liners Rod mills: • Shell liners • Head liners • "Wedge ...
of the mill. A new liner design was then designed by increasing the width of the lifter top from 12.5 to 15 cm and increasing the lifter height from 16 to 26 cm to enhance the liner life. Keywords: AG/SAG Mill, Shell Liner, Gol-E-Gohar Iron Ore, Wear Profile, Non-Uniform Design. 1. Introduction Mill liner design influences the grinding
Either SAG mill or ball mill,grinding liner could protect the cylindrical shell and affect the movement of grinding media.The shape and material of the lining are also different to meet the requirements of various working conditions (grinding or fine grinding).
