Nov 26, 2019 How does a sag mill work The working principle of the self-grinding machine is basically the same as the ball mill, the biggest difference is that the sag grinding machine uses the crushed material inside the cylinder as the grinding medium, the material constantly impacts and grinding to gradually pulverize.
2. Sarcheshmeh copper complex SAG mill This work was carried out at the Sarcheshmeh copper complex located in SE Iran. At the new concentration plant of the Sarcheshmeh copper complex, which comprises two parallel phases, two (9.75 4.87 and 9.15 4.87 m) SAG mills are used to grind a feed all under 17.5 cm that is.
In a mining plant or processing mill, they have a big grinding circuit for crushing raw material, these are usually Ball or SAG mills. Inside these Sag Ball mill are big steel balls that grind ore via an impact process. In simple terms, these hard metal steel balls get to the top of the rotating chamber and fall down crushing the ore being processed. It grinds it up into a compound to make processing easier. You'll find a similar process in sugar cane mills.
Copper Mountain first feed to the SAG mill occurred in late May, 2011. The circuit began ramp up in mid-June of that year, with consistent operating run times on the SAG and Ball mills. Plant throughput in the first months was quite variable with throughput tonnage greater than 40,000 tons one day and less than 25,000 the next on some.

Working Of Cement Making Plant Ball Mill And Sag Mill. SAG mills use 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.
SAG mill control fundamentally means managing the load in the mill by adjusting the feed rate of ore to the mill and or manipulating the rotational speed of the mill. The best way to measure load is to mount the mill on load cells. The load cells are calibrated to measure the total weight of water, grinding media (balls) and ore in the mill.
