The semi-autogenous (SAG) mill grinds materials with steel balls as the grinding media, and is the main grinding equipment in industrial production. Liners are equipped in the internal of the SAG mills, which have the function of protecting the barrel and adjusting the trajectory of the medium.
The Selection and Design of Mill Liners MillTraj. mills in the older plants that had many mills in parallel In fact this is generally still the case in the multistream plants where mill liner design and selection is only tackled on a cost consumables basis However the gains to be had through good liner design and selection are just as great as on the large SAG mills

To a more significant degree than in other comminution devices, SAG Mill Liner Design and Configuration can have a substantial effect mill performance. In general terms, lifter spacing and angle, grate open area and aperture size, and …
Larger, more competent material consumes mill volume and limits throughput. A number of operations have implemented a secondary crushing circuit prior to the SAG circuit for further comminution of primary crusher product. Such a circuit can counteract the effects of harder ore. coarser ore. decrease the size of SAG mill required, or rectify ...
Figure 1 shows a schematic cross section of the Chadormalu iron ore complex SAG mill which consist of two rows of liners; (1) feed-end shell liners and (2) discharge-end shell liners. The present case study has been conducted on these well-worn liners. The liners were replaced after comminution of 800 thousand tons of iron ore.

Qiming Casting manufactures AG mill liners, SAG mill liners, and ball mill liners by chrome-moly steel (It is called L2B and L2C grade in Australia standard). This material has excellent wear characteristics with some impact resistance, generally now used for discharge grates where slightly better impact resistance is required compared to the ...
SAG Mill Liner Design In summary: A broad range of AG/SAG circuit configurations are in operation. Very large line plants have been designed, constructed, and operated. The circuits have demonstrated reliability, high overall availabilities, streamlined maintenance shutdowns, and efficient operation.
Component wear, regardless of whether it involves bearings, lifters or other parts of the machine, is a constant concern for SAG mill operators. Industry suppliers have developed a wide variety of liner shapes, composite-material combinations and fastener systems to make liner replacement safer, quicker and more cost-effective in the long run.
stresses in large SAG mills helped to drive the development of greatly improved liner materials. However, this cost engineering approach ignored the mill performance and overlooked the other key function of mill liners. The second primary function of a liner is to transfer rotary motion of the mill to the grinding media and charge.
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.

SAG Mill Liners. SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. SAG mill is usually used to grind large pieces into small pieces, especially for the pre-processing of grinding circuits, thus also known as primary stage grinding machine.
GTEK® GRINDING MILL LINERS. According to the different grinding media and grinding materials, the mill can be divided into: ball mill, rod mill, AG mill, SAG mill, vertical mill and so on. When working, the motor rotates the cylinder through the transmission gear, sprocket or belt, and the centrifugal force generated will bring the grinding ...
The material of SAG mill liners use low or high Carbon Cr-Mo Alloyed steel,the carbon content depends on the working condition of the mill. To choose the right material for the right application is our mission, we are always working together with our customer to achieve this .
The mill's continuous operation is interrupted when the mill liner — which comprises riser bar plates that protect the original casing and provide required lift required for grinding action — wears out after months of processing abrasive material. Overall, SAG mills are expensive to operate due to several factors, including high power ...
In general, the SAG mill manufacturers will control the addition amount of medium such as steel ball at 2-8%, so that the capacity of semi SAG mill to process materials can be increased by 10-30%. The SAG mill liners wear will increase by 15% due to the impact of medium such as steel ball during the SAG mill operation.
The style of a SAG mill liner is driven by the material of building and construction and also the application, as well as limited by casting, molding, and taking care of constraints. For huge mills with wide inlet trunnions, in excess of 1.5 m, liner handling types of equipment are currently in common usage, and also this has actually permitted the development of large …
In a paper presented to the 9th Mill Operators' conference in 2007, Dr. David Royston of Royston Process Technology said, "chrome-moly alloy steel combines high impact resistance and good wear life and is still the dominant material of construction for SAG mill liners.
SAG Mill Liners for Discharge Grate Special Features: The material of SAG mill liner castings 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.
This work characterizes the wear behavior of pearlitic SAG Mill liner material for in-service and laboratory worn samples. The abrasion tests (Dry Sand/Rubber Wheel Abrasion Test – DSRW) were carried out on samples removed from the undeformed region of the same liner – applying different normal loads (from 22 N to 380 N).The electron microscopy …
This material also called AS2074 L2C steel.This steel is now considered the main material used for SAG mill liners. There are a number of variations with either different carbon or chrome contents. The variations tend to have a bearing on the size of the liner and its section thickness.
The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...
