MINE LINERS

The two main functions of a mill liner consist in protecting the mill shell against wear and in transmitting the energy of the mill motor to the grinding charge to carry out the required size reduction in the most efficient way. For a mill liner, the design as well as the liner material are to be considered. The required movement of the mill charge to carry out effi-

[PDF] Semi-autogenous grinding (SAG) mill liner design and

SAG mill liner development draws primarily on practical experience from SAG milling operations supported by computer-based modeling of charge motion in SAG mills and on established good design practice. Liner design needs to respond to the process aspects of mill liner action that are critical to good SAG mill performance, i.e., the impact of shell liners on the grinding action and of grates

Slipjoint Liner Mill Relief Fixture

May 14, 2015· May 12, 2015. #1. Slipjoint Liner Mill Relief Fixture. I thought I'd post some pic's of a fixture I finished up yesterday for mill relieving the liners on slipjoints. The ideal way to do this would be with a rotary table, but since I didn't have $200 to $300 to spend on one right now. I though I would see if I could put together a fixture out

How to Select Grinding Mill Liner Alloys for Optimum Wear

Jul 25, 2019· Jul 25, 2019· One test was made in a 12′ – 2″ diameter x 14′ long rod mill with medium height overflow discharge and Noranda type shell liners. The grinding media are 4 – 3/8 inch diameter rods of 1090 steel at about 269 – 311 Brinell hardness. Mill speed is 13.3 rpm, which is about 59% of the theoretical critical speed.

Relining efficiency and liner design for improved plant

Nov 01, 2015· Improving the liner design and material could also improve the grinding efficiency while enhancing the life of the liners. As illustrated by the dashed line in Fig. 2, the optimum throughput could correspond to less frequent relining (e.g. 2 relines per 6 months) which will introduce additional benefits..

Rod mills, how they function

The heavier rods acting upon the lifters and liners result in greater wear on the mill liners. Rod mills normally carry 35 to 65% rod charge by volume. The limits on charge level are (1) keeping the feed end trunnion open so that feed will get into the mill, and (2) keeping the rod charge low so rods will not work their way into discharge
