comminution circuits is towards the large SAG mill with or without secondary ball milling. Autogenous and Semiautogenous (AG/SAG) grinding mill circuits are among the common grinding devices in
AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill. Because of the range of mill sizes available, AG/SAG milling can often be accomplished with .

CHARGE LEVEL. Maintaining an optimum charge in a SAG mill remains one of the fundamentals for efficient mill processing. If the charge level or the ball to charge ratio is incorrect, breaking liners and/or increasing power consumption is inevitable and can only result in .
With improved SAG mill control stability, the mill load can be optimized to increase crushing performance and produc tion capacity. Along with the potential for greater produc tion, BrainWave also allows you to operate your mill at maximum efficiency.
mill as the inside mill volume for ore grinding is a function of volume of mill liners. The measurement of liners can also be used to estimate the grinding performance and the monetary output of the mill. Terminology This section briefly describes the important terms and which has been frequently used in .

Grinding Mill Charge Detection Sensors. The throughput and efficiency of a SAG mill depends on the volumetric load: An overloaded mill has reduced coarse ore breakage, as the cascading balls and rock cannot drop far enough, reducing kinetic energy for breakage.
SAG and ball mills have grown in size and there are now many operational mills in the range of 28–40 feet in diameter with installed powers ranging between 8–20 MW.
Dec 19, 2014· Advantages of SER drives for SAG mills. For large mills requiring variable speed, the wound rotor motor and SER drive are economical for a total rating of approximately 2MW to 16MW. Above 16MW, the gearless drive (cycloconverter) is typically used because gearboxes and pinion gears reach their present limit in size.
Mill liners developed by Multotec include Ball Mill Liners, SAG Mill Liners, AG Mill Liners, as well as Scrubber Liners. Focusing on good fitment of liners, in which Multotec are experts, results in reduced installation downtime which, in turn, facilitates increased production.

In the SAG mill testwork when the steel is added the SAG product classification size and ore feed size distribution is varied. If necessary, pebble crushing or mill speed can also be investigated. All tests are evaluated on the basis of feed rate, power consumption and product size analysis.
The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls.
