What is the difference between a SAG mill and a ball mill? A SAG mill uses larger rocks or ore fragments as grinding media, while a ball mill uses smaller grinding media such as steel balls. Additionally, a SAG mill uses a minimal ball charge of 6 to 15%, while a ball mill requires a higher ball charge of 20 to 40%.
(EGL) SAG mill driven by a 24,000 kW gearless drive. The SAG mill feeds two FL ball mills each 26 ft. in diameter × 40 ft. long (EGL), each driven by a 16,400 kW drive. The SAG mill is one of the largest volumetric capacity SAG mills in the world and represented the first 40 ft. SAG mill in Peru (Garcia & Villanueva, 2013 [1]).

This article will take you to explore so as to help you choose the appropriate …
In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rod mill or ball mill, the ore in order to …
SAG mills grind ore by lifting it and a small amount of grinding media and dropping it inside a horizontal mill. Ball mills are smaller and use a higher concentration of iron balls to pummel the ore. The mills can operate in an open grinding circuit, feeding secondary grinding systems, or in a closed circuit generating a fine product.
Ball Mill Shell. mining ore difference between a sag and a ball mill offers 159 ball mill shell products. ball mill for hematite, iron ore, copper ore, dolomite, bentonite, limestone. ... reasonable solutions for any size-reduction requirements including, Difference between sag mill and ball mill, quarry, aggregate, and different kinds of ...
According to Smith [22], an option to install an AG/SAG mill in preference to a normal tubular ball mill may be considered when the unconfined compressive strength of the ore is less than 180 MPa, the Bond crushing work index is less than 20 kWh/t and the Bond rod mill work index is not significantly higher than the Bond ball mill work index ...
Ball mills, conversely, contain grinding media up to 50mm in diameter, occupying between 25% - 40% of mill chamber volume. To effectively reduce material size, each type of mill needs to generate different charge load actions, or the type of motion characterised by the mill's contents. SAG mills generate higher levels of impact reduction and ...
Single stage SAG Mills are very beneficial in reducing CAPEX for plants with a staged throughput approach. When future tonnage is to be increased, the SAG Mill can feed downstream ball milling to boost capacity. Fuller-Traylor SAG/AG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW.
In this example the SAGDesign (SDT) ore hardness is 10 kWh/t (to grind the ore from F 80 152 mm to T 80 1.7 mm) and the SAG ground Bond Ball Mill Work Index is 15 kWh/t. Table 2 shows alternate equipment selections that will produce 471 t/h, (10,400 t/d and 3.8 million tonnes per annum) at 92% availability.
mill. As such, primary ball mills should be designed with the rod mill work index, and single-stage ball mills should be with both the rod mill and ball mill indices. This is because it is common to observe a difference (sometimes significant) between the rod mill and ball mill index values for a given ore type (McKen, Verret, & Williams, 2006). On
Semiautogenous-single stage. These circuits are not a good choice for many orebodies because it is not logical to expect one machine to be as efficient on 150 mm ore as it is on 100 micron ore. Semi …
The pairing mill combination of a SAG/Ball mill is common in copper/gold mines for that reason. This combination can aim for a fine product sizes are around typically 100-200 micron whereas a Vertimill or ISAMill are finer at 20-40 micron or smaller. ...

Another major difference between raw mill and cement mill is the equipment used to grind the raw materials into clinker and cement, respectively. In the raw mill, vertical roller mills are used to grind the raw materials into fine particles. On the other hand, in the cement mill, ball mills are used to grind the clinker into a powder.
