comminution processes. The test work determined the Bond ball mill work index and hardness parameters related to semi-autogenous mill grinding (SAG) and high pressure grinding rolls (HPGR) crushing. The grindability test results indicated that the sample is moderately hard for grinding by ball mills but is very hard for milling by SAG mills.

Each wire has a name, both 4 wire and 6 wire load cells have +input, -input, +signal and –signal wires. A 6 wire load cell will also have a +sense and a –sense wire which are sometimes referred to as +reference and –reference. When a load cell is in use, the cables will measure through resistance. The length of the cable will make a ...
SAG Mill Success—Start with the Basics. SAG mills are often flexible enough to accomplish the same size reduction provided. by two or three stages of crushing and screening, a rod mill, and some or all of the. work of a ball mill.

Due to well-established relationships with equipment suppliers and commercial laboratories worldwide, DRA Global's process engineering team and process designs are unrivalled in the industry and are known to add value to all ...
The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...

The SAG Mill has a mill diameter of 24 feet and an Effective Grinding Length ("EGL) of 18.5 feet and a structural charge mass of 315 metric tonnes. The structural design ball charge is 11% with a ...
1. SAG mill is the primary tool for grinding. SAG mill is used before the other mills. Ball mill is a secondary, and it is used after the SAG mill. 2. SAG mill breaks the raw material into pieces for the further grinding. Ball mill is used to grind the pieces of raw material into. powder-like structures. 3.
The ball mill circuit is closed with 6 Krebs super D20 cyclones. Line 2 grinding circuit is comprised of a 24 by 12 foot 4000 horsepower Fuller variable speed SAG mill followed by a 16.5 by 30.5 foot 5000 horsepower Fuller ball mill. SAG mill recycle from the primary discharge screen (+5/16 inch) is processed through a 1560 Omnicone ...
