The shell liner type, rotation speed, and ball filling percent are the key factors influencing the charge behavior inside the SAG mills, and consequently, their performance. In this work, the milling operation of industrial SAG mills is investigated using the Discrete Element Method (DEM). First, an industrial SAG mill with dimensions of 9.50 m × 4.42 m that has a Smooth-type liner is simulated.

Liners furnished with heavy lifter bars are also sometimes used and in such a case the locking of the ball charge to the shell must be very effective. Nevertheless, although a few vague general statements to the effect that a lifter mill gives a product with different size characteristics to that of a smooth mill have appeared, the point does ...


Most of all type of Ball Mill Liner are always used to protect the inner shell of the cylinder from being impacted and worn directly by material and grind-balls. Sakar's Ball Mill Rubber Liner also protects the inner shell of the grinding mill by material and grind-balls with long life and better performance.Our Ball Mill Rubber Liners are designed to avoid unnecessary downtime and service ...


The lifter wear occurs most strongly on the protruding lifter bars, reducing the lifter heights and shape over time. In order to evaluate the effect of the lifter life cycle on mill performance, a series of DEM simulations were run for lifter shapes and …


The Masbate gold deposits are situated on the island of Masbate, 350 km south of Manila. A new plant was commissioned in April 2009. The grinding circuit consists of one semi-autogenous (SAG) mill 9.75 m 4.27 m, two ball mills 5.6 m 7.1 m and a pebble crushing circuit, which is usually called a SAG-ball mill-crusher configuration. The SAG mill was originally equipped with radial pulp lifters.

Important advances have been made in the last 60 years or so in the modeling of ball mills using mathematical formulas and models. One approach that has gained popularity is the population balance model, in particular, when coupled to the specific breakage rate function. The paper demonstrates the application of this methodology to optimize solids concentration in ball milling of an iron ore ...
