The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and non-ferrous metals. The ball mill can grind various ores and other materials either wet or dry.
in the designer's ability to design the correct mills or accurately predict throughput in a large SAG mill. Cynicism about SAG milling and tonnage capacity is perhaps best explained by the comment from a senior mining consultant who recently said, "if a SAG mill can process design tonnage, it .
Ball Mill Discharge Trommel Screen. The Ball Mill Discharge Trommel Screen has wide application in practically every type of placer work, in gravel plants, and in ore-dressing. This type of screen is particularly adapted for screening at coarse sizes, or at finer sizes if spray water can be used freely without interfering with screening.

SAG mills are characterized by their large diameter and short length as compared to ball mills. The inside of the mill is lined with lifting plates to lift the material inside the mill, where it then falls off the plates onto the rest of the ore charge. SAG mills are primarily used at gold, copper and platinum mines with applications also in ...

Plants that have competent ore and conventional SAG circuit have reached 50% of design capacity and all of them have needed the addition of secondary crushers stages to reach design capacity. Some people is now designing SAG circuits for competent ores where they are adding 2 stage of crushing to feed the SAG mill with 45 mm.
In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rob mill & ball mills, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for subsequent treatment.
There are a number of SAG mills in operation around the world with diameters reaching up to 40 ft. These operations continually invest in new technologies to improve their energy efficiency and capacity in their SAG circuit. Commercial SAG mill performance is determined by a large number of variables, both mine-site variables and mill variables.

The ore is ground into a fine powder by large rotating mills. The two types used in the Mission South Mill are called SAG (semi-autogenous grinding) mills and ball mills. SAG mills use larger pieces of ore to break up the smaller pieces (autogenous — does it by itself). The larger pieces break down as well.
Case study 1: Model and optimize SAG-only circuit An existing large tonnage copper operation was operating with a single 38 ft, 19.4 MW SAG mill followed by two 25 ft 11.1 MW ball mills. The SAG mill was operating in a SAG-only configuration, closed by a vibrating screen. A base-case model of the existing circuit was

Ore Grinding Mills are used for the fine grinding as the last step in the reduction of an ore prior to concentration (gravity or flotation) or cyanidation.Practice varies, depending upon the type of ore and the amount of reduction required. In addition, some of the older properties continue with methods that perhaps are not considered the best in light of recent improvements but that cannot be ...

SAG mill itself and not on the test work program. Stated another way, money invested in a large SAG mill is an investment that can produce handsome returns if extra production is needed or simply to give the mine the option to mill the hardest ores at design throughput rates.
The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls. The grinding process reduces the rock to a slurry. The SAG mill is a large revolving cylinder.
