Whether you require smart meter verification wireless temperature monitoring of rotating equipment precise control of reagents addition froth camera and level measurement or precise analytical measurements for process and safety we have you covered
2014-10-1Developments in SAG Mill Design and Operation Over the last few years SAG mill manufacturing technology has advanced rapidly. The bounds of mill sie have been pushed from two directions. Firstly the advent of ring motors has removed the constraint applied by the power that a single pinion gear was able to transmit
2013-4-12Ball Mill Sag Mill AG Mill Roller Press HPGR HRC Tunnelling . or driveline failure. This is often a result of torque overloads caused by material getting stuck. . Nevertheless all mechanical drive components need correct service and maintenance to ensure reliable performance
The case study is being presented at the SAG Conference 2019 held in Vancouver from 22nd September 2019 to 26th September 2019. The abstract for the paper being presented is as below. A Chilean Copper mine with 40 feet diameter SAG mill processing 4300 tph was facing very low avaliabilty due to continues unexpected shutdowns for failures on
SAG mill liners which protect the equipments shell must be replaced when they wear out impacting the operations budget and unscheduled downtime. As a result the industry is continually exploring new ways to produce more failure-resistant longer-lasting liners
The wear and failure analysis of shell liners of a grinding mill is investigated. Metallurgical and tribological studies were conducted on the worn liner of a semi-autogenous grinding mill in Chadormalu Industrial Complex. The chemical analysis wear mechanism microstructural variations and mechanical properties in different sections of the worn liner were evaluated using visual inspection
The SAG mill is often one of the largest pieces of mining equipment and is key for operations. Often used in the mining process of precious metals the SAG mills break up
2012-9-11The SAG mill draws only 50 of its installed motor power whilst treating the softer transitional ore. However attempts on Friday night to restart the mill using one motor were unsuccessful. The failure of the SAG mill motor follows a failure in March of one of two identical ball mill motors
2016-5-31Valley Forge has recently developed a liner bolt innovation to improve the reliability of mill liners and liner bolts in ore grinding mill applications. Recently concern has been raised about liner breakages triggered by stress concentrations found at the base of the liner pocket where contact is typically made with the bolt head. Liner bolt customers have also reported problems of racing

Large SAG mill linerSAG mill liner are important components of the host machine. The main function is to protect the mill shell and transfer energy to lift the grinding balls and mineral and crush and grind. With the increase of the diameter of the main machine of the mill and the complexity of the working conditions higher requirements have been placed on the liners
