SAG Mill Liners

AG /SAG Mill liners is divided into medium Cr-Mo liner plate (A kind of casting steel with the chromium content at 4-6%, the carbon content at 0.4-0.8%)and low Cr-Mo Liner plate(A kind of casting steel with the chromium content at 1.2-2.5%, the carbon content at 0.3-0.6%). Its distinctive feature is to adopt multivariate alloy design. It increases carbide content in the medium carbon alloyed steel, through increasing the Cr-Mo content, the strong carbide forming elements, so as to improve its heat-resisting, wear-resisting performance. As a result, its high strength, strong toughness and good wear resistance properties represent the relatively high level of metal wear resistant materials.

Lifter Bar

The lifter bar or lifters  Usually made of cast steel  have been used as cylinder lifter ,SAG There are other solutions, use combined the rubber and steel to form a lifter, which the mill are elements of permanent change in AG/ SAG mills, because the product of the movement of the load wears out continuously until they reach a point where they must be removed and exchanged for new elements.

AG/SAG Mill Parts Description:

Autogenous (AG) and semiautogenous mills (SAG) are used for the coarse grinding of various ores, (such as gold, copper and iron ore). The wet grinding plant for gold ore consists of an SAG mill and a ball mill. AG/SAG Mill can accomplish the same size reduction work as two or three stages of crushing and screening. So often used in grinding at modern mineral processing plants, and reduce the material directly to the desired final size or prepare it for the following grinding stages. 

AG /SAG Mills operate by lifting ore/grinding media and dropping it on the operating bed of the mill charge. High impacts from lifting ore and media promote impact breakage which is the primary mechanism for size reduction in the mill. Via the use of sophisticated instruments and software, we closely monitor the mill impact location to boost the grinding efficiency of your operation.

The AG/SAG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW. Customized, fit-for-purpose mill parts and components that aim to improve the reliability of your machine. From a parts supplier to a full-service partner, Casteel is here to support you, no matter the brand of your grinding mill.
