upcoming sag mill liners

Mill relining is the most specialised maintenance task in a mineral concentrator. Almost invariably the AG, SAG and Ball mill liner lives dictate the shut-down dates of the concentrator. The replacement of the mill liners determines the length of each concentrator shut-down.

Mines (WA) 36ft SAG mill the number of Outer Head Liners was reduced from 36 to 18 pieces and in doing so reduced the time to replace them by 9 hours at a cost downtime saving of about U$25,000 per hour. In this case the liners sections are 3.5 t each.

FL has launched PulpMax composite mill liners, which are high-performance semi-autogenous grinding (SAG) and ball mill liners for all mineral processing applications. The composite design incorporated in the PulpMax mill liners ensures improved worker safety. Processing > Operational-excellence. 23 May 2019. share.

R&D culminated in pilot-scale operational trials at the Akbakai gold mine (Kazakhstan), owned by JSC AK Altynalmas, in 2020, where SAG mill rejects of hard underground quartz/gold ore were processed. The mutual intent and purpose of the tests was to observe and define wear characteristics of the eHPCC grinding chamber liners (roll surfaces).

In New Gold's first-quarter 2018 results, the company cited several "operation and mechanical challenges that impacted availability," such as plugged apron feeders, premature motor failure on the cyclone feed pump and additional time needed to replace SAG mill liners.

Based on experience, mill-liner designs have moved toward more open-shell lifter spacing, increased pulp lifter volumetric capacity, and a grate design to facilitate maximizing both pebble-crushing circuit utilization and SAG mill capacity. As a guideline, mill throughput is maximized with shell lifters between ratios of 2.5:1 and 5.0:1.

Mill liners provide the replaceable wear-resistant surface within grinding mills; they also impart the grind-ing action to the mill charge, and at the discharge end, remove the ground contents of the mill. In recent years, as SAG mills have grown in size, the process aspects of liner design and their impact on mill performance have

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 ...

Then, in the late 1980s when the price of copper rose quickly from a low of $0.62/lb to a high of $1.62/lb, this substantial increase in price further fuelled the industry demand for larger diameter SAG mills, with mill power quickly doubling from 15,000hp to 30,000hp (11,000-22,000kW). Unique Solution Boosts Efficiency.

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 …

SAG Mill Liner Design Special Features: The material of SAG Mill Liner Design 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 …

SAG circuits may employ low to relatively high ball charges (ranging from 2% to 22%, expressed as volumetric mill filling) to augment autogenous media. Higher ball charges shift the breakage mode away from attrition and abrasion breakage toward impact breakage; as a result, AG milling produces a finer grind than SAG milling for a given ore and ...
