Special Features for SAG Mill Liner Plate in AS2074 L2A: The material of SAG mill liners are low C or high C Cr-Mo Alloy steel,which depends on the specific working condition of the SAG mill. The hardness of AS2074 L2B is HB310-HB380. We can make big size SAG mill liner castings with Sodium Silicate Sand Process & Resin Sand Process.
Granted the packing is not as severe as in wet mills, as the presence of water can cause some ores to behave like a self-setting concrete mix. Liner design in terms of lifter spacing should consider the best spacing for charge lift. Quality of liner fit up and casting accuracy will determine the spacing between liners.
Application of the proposed method in a 9.75 × 4.88 m SAG mill indicated that the liner wear profile along the liner length is non-uniform and the highest wear occurs between 1.25 m and 2.75 m of the mill length. The liners of the first half of the mill from the feed end showed more wear (19.1 g/t) compared to that of the second half (17.1 g/t ...
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.
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 …

As per the U.S. Steel Industry, the U.S. steel production fell by 12.7% year over year at the ending of March 2020. This in turn, has adversly affected the demand for mill liners across the U.S., U.K., Germany, china, Italy, India and other major countries. However, the mill liner manufacturers such as, H-E Parts International, FL and ...
Mill linings, Weir Rubber Engineering, Salt Lake City, UT 84126, United States of America . ABSTRACT . Dramatic shortcomings of mill liner designs, especially of large SAG mills, - such as rapid failure and even mill shell damage arising from impacting of the charge directly on the liner, and unsuitable
Due to its strong lifting capacity and excellent grinding performance, the trapezoidal liner is widely used in the SAG mill. The structure of the trapezoidal liner is shown in Fig. 1, the main dimensions are: dip angle (tau), length of the top edge (L) and height (h).Dip angle (tau) determines the trajectory of the mediums in the SAG mill, which directly affects …
Safe and speedy replacement. Thinner mill liners result in a larger volume inside the mill. This means you can have a higher charge level. Using composite liners also cuts the weight of the liners to about 50 percent of standard steel cast liners, making it possible to work with a higher ball charge level without increasing the total weight of the mill.
Polycorp - AG/SAG Mill Liners. AG/SAG Mill Liners. We have supplied rubber pulp lifters for SAG mills up to 40 ft in diameter. We are pioneers in the design of both radial and curved pulp lifters, also design and manufacture Rubber / PolyStl™ grates and discharge systems. Mining.
For a conventional rubber lined ball mill, based on the amount of gold behind the liners: The distance is about 0.05mm (800oz in an 8x12ft mill), but much higher in steel lined mills. If you eliminate the flex space completely then the impact acts on the mill shell causing damage, the can crack the feed end panel or shell to panel joint when ...
The chord produced by spacing equal to two times mill diameter (ft.) or 470 mm (18.8 in.) is desirable. Shell liners so designed can minimize charge "packing" problems and still provide sufficient lifts for normal mill action to lift the charge and hence draw power and do work (comminution). Mill end plate bolt spacing.
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. ...

Chrome Moly White Irons SAG Mill Liner (600 to 700BHN) This cast material is considered to be the ultimate developed and used to date for abrasion resistance in Milling. It is commonly used in cement mills and some of the largest Ball Mills in the world and where performance has not been bettered to date. Category: Industry New By tomaschien 17 ...
Mill liners protect the mill shell from wear and transfer energy to the grinding charge. Careful balance is needed to optimise these differing requirements, as poor liner design has detrimental effects on milling performance – and on mill liner life. Mill liners developed by Multotec include Ball Mill Liners, SAG Mill Liners, AG Mill Liners ...

The SAG mill's steel liners were failing to meet the required service life. To remedy the problem, the supplier had added more material to the liner design. But this created its own challenges, reducing the effective grinding volume and adding weight to the mill that was pushing bearing pressures dangerously close to limitations.
This tool, according to RME, is suitable for larger mills. Each unit requires a Thunderbolt Power Pack to supply the electrical and hydraulic needs of the hammer and powered suspension options. The hammer can operate with any standard three-phase supply (380, 415, 480, 525, 575 or 600 volts at 50 or 60 Hz).

Material for AG/SAG Mill Liners. MGS Casting had success to use ASTM 2074/L2B alloy steel to manufacture AG/SAG mill liners. Under this material, our mill liners' span life can be obviously improved. Our Australian customers had ordered more than 3000 tons per year of this material mill liners. Grade.
A Megaliner™ element integrates multiple lifter and plate rows and has a minimum number of attachment points. In some cases, the lining consists of up to 80% fewer parts! It covers a large area of up to 8 m² and is light-weight in relation to size. Being several times larger than a traditional lining enables much faster installations.
Single stage SAG Mills are very beneficial in reducing CAPEX for plants with a staged throughput approach. When future tonnage is to be increased, the SAG Mill can feed downstream ball milling to boost capacity. Fuller-Traylor SAG/AG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW.
