Made from composite material, the outer pulp lifter is also double width, but only about half of the weight of the steel liner. This success was just the beginning, opening the door for us to address other issues we had identified and further improving SAG mill performance.
E&MJ asked one of Australia's experts in SAG-mill liner technology, Dr. David Royston, about recent trends in SAG milling practice and how this has affected the design of liners. "In recent years, the trend to smaller top-size ore feed into SAG mills has been matched by a trend toward smaller but more balls in the SAG mill charge.
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 …
After using mill rubber liner, there is almost no slurry leakage in screw hole, which improves the operation rate of SAG mill and is conducive to safe and civilized production. In conclusion, based on the development of science and technology, Kosga will continuously improve the wear-resistant materials to up the performance of mill rubber liner.
Polycorp PolyKombo™ Liners are a one piece liner with steel lifters and rubber plates designed for use in SAG, AG or Ball mill applications. Rubber Mill Liners are chosen for most Primary, Secondary and Tertiary Ball Mills. In many cases rubber components are best suited for specific areas in AG and SAG mills.
Rubber and Alloy Composite Liners. Composite liners are a new type of liners, particularly engineered by TOMINE to address SAG mill leakage due to discontinuous cracks in large alloy liners or loose liner bolts with insufficient pre-tightening force, and over-grinding of material.

The Opti-Liner system can be made in full rubber or Poly-Steel to suit a variety of milling applications in Ball and SAG Mills. A selection of fixing systems are available for each mill that best suit your method of installation and liner handler capabilities. Reducing steel liner mill weight is often a challenge but with the Opti-Liner system
A comparison of SAG and ball mill charge actions is shown below. Figure 1 shows the sliding abrasion action of a ball mill while figure 2 depicts the cascading impact action of a SAG mill. The geometrical differences in the liner system lifters can also be seen. Figure 1: Sliding-abrasion action in a Ball Mill
ear for the mill and has the ability to accurately detect ball-to-liner impact occurrences. By quantifying the charge toe angle, or the media angle (β dynamic ), on each rotation, a precise control strategy based on the internal dynamics and volumetric loading of …
This product also reduces the risk of damage to the outer shell due to design. Another unique feature of the Easy Release Liner Bolt is the ability to reuse the bolt. The nut is the only consistent consumable. Technical components of the Easy Release Liner Bolt are consistent with Mill Liner bolt range.

The SAG mill was relined in April 2018 incorporating the new design enhancements. These initiatives also ... quickly apparent that the Feed End middle liner and Feed End outer liner were wearing across the middle joint line from the eye of the operating charge volume. This led to both parts being changed out together
SAG Mill Liners include: feed head & discharge end as well as grates (both outer, middle and inner), pulp lifters (dischargers) shell lifter bars and plates.
A longer lasting mill liner means less downtime for maintenance or new liner installation. A 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.
The SAG mill liners wear will increase by 15% due to the impact of medium such as steel ball during the SAG mill operation. Later, people were inspired by the semi-automatic grinding mill, adjusted the amount of medium in the semi-automatic mill, and evolved our most common ore dressing mill, ball mill and rod mill .
