Ni-hard can be used as liner plates in fully autogenous operations because there's no point impact action of 4 to 5″ diameter steel balls as in semi-autogenous grinding. Lifter spacing around the shell periphery has generally been satisfactory with the number of lifters at twice the inside shell diameter in feet.
the trend in large SAG mills has been to use wide-spaced shell lifters with large lifter face angles, primarily to reduce packing and ball/liner damage, and to use larger, hence fewer, mill liner parts to reduce downtime at liner change-outs. Key words: Comminution, Grinding, SAG mill, Mill liners Paper number MMP-07-002.
Polycorp PolyKombo™ Liners are a one piece liner with steel lifters and rubber plates designed for use in SAG, AG or Ball mill applications.

Ball mill： Ball mills are the most widely used one. Rod mill： The rod mill has the highest efficiency when the feed size is <30mm and the discharge size is about 3mm with uniform particle size and light overcrushing phenomenon. SAG mill: When the weight of the SAG mill is more than 75%, the output is high and the energy consumption is low ...
SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. [6] [7] The largest SAG mill is 42′ (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor. [8] A SAG mill with a 44 ...
1. SAG mill is the primary tool for grinding. SAG mill is used before the other mills. Ball mill is a secondary, and it is used after the SAG mill. 2. SAG mill breaks the raw material into pieces for the further grinding. Ball mill is used to grind the pieces of raw material into. powder-like structures. 3.
SAG and Ball Mill Liner grind material through different actions and are usually applied in different stages of the process. SAG mills usually have a larger diameter than length and are used to reduce large feed size ore (typically ~300mm) down to ~3mm, often for further grinding in a secondary process.
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).

They noted austenitic manganese steel and chrome-moly steels have been materials of choice for SAG- and ball-mill liners, although the trend has been toward the use of higher-carbon chrome-moly steels for SAG mills. Where ball mills are concerned, the most durable alloys are now high-chrome irons and chrome-moly white irons, both of which ...
Oleg D. Neikov, in Handbook of Non-Ferrous Metal Powders, 2009 Tumbling Ball Mills. Tumbling ball mills or ball mills are most widely used in both wet and dry systems, in batch and continuous operations, and on a small and large scale.. Grinding elements in ball mills travel at different velocities. Therefore, collision force, direction and kinetic energy between two or more …
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 ...

According to the material classification, the common ball mill liners mainly include high manganese steel mill liners, alloy steel mill liners, rubber mill liners, ceramic mill liners and magnetic mill liners. The mainstream ball mill liners materials currently used in the market are alloy steel and rubber.
Uses of a Ball Mill Liner. The role of a ball mill liner is to give the mill heads protection against wear and tear thus increasing their lifetime and creating optimal grinding efficiency. The design of a ball mill liner depends on the drilling pattern of the mill heads, the rpm speed of the mill, the maximum grinding diameter of the media and the percentage of media filling.
