Mill (grinding) - Wikipedia
SAG mill. SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.
What's the Difference Between SAG Mill and Ball Mill ...
SAG mill is usually used to grind large pieces into small pieces, especially for the pre-processing of grinding circuits, thus also known as primary stage grinding machine. Based on the high throughput and coarse grind, AG mills produce coarse grinds often classify mill discharge with screens and trommel.
What's a Mil ? - Choosing the Right Mil Thickness
Aside from the dimensions of the bag, the mil thickness is another critical component in selecting the right plastic bag for your needs. A Mil is a unit of measurement used to measure the thickness of film in thousands of an inch; 1 Mil = 1/1000 inch. While simple in principle, it's very hard to visualize.

Difference Between Sag Mill vs Ball Mill - mech4study
SAG is the abbreviated form for Semi-Autogenous Grinding Mill. This type of Mill is used for grinding large fragments into small pieces. Pieces are then used for further processing. The SAG mills are generally used in pre-processing of any type of material in grinding process. SAG mills are also known as first stage grinders.

A client mill ran two periods with different liner designs. The authors tag the two periods with Period 1 and Period 2. Direct comparison between two periods is given in Table 1, which lists throughput, SAG power, and SAG efficiency for the two periods. SAG efficiency is defined by throughput divided by SAG power.
Main Difference Between Synchronous and Asynchronous Motor
The synchronous motor is a type of AC motor that runs at synchronous speed. The asynchronous motor is a type of AC motor that runs on speed less than the synchronous speed. It operates on the principle of magnetic interlocking between rotor and stator field. It operates on the principle of electromagnetic induction between stator and rotor.
