Actual comminution circuits consist in most of the cases in coarse crushing, SAG milling, pebble crushing and secondary ball milling. In these circuits the SAG mill is the largest energy consumer. In many engineering projects either a power equation and/or a specific energy equation are used for the designing of these mills but not always with ...
By comesa_web Inglés. It's important to point out that in a SAG mill, the crushing load is composed of two components; the mineral rocks and the iron balls. Thus the mineral type affects SAG mills more than ball mills. Due to the heterogeneous nature of the foundations, the minerals don't possess a single hardness.

Energy requirements for crushing and HPGR options can now be determined in addition to AG/SAG mills, and with Mic, ball mills. The results from conducting the SMC Test are used to determine the so-called drop-weight index (DWi) which is …
approximate size of SAG ground product to the ball mill. The point in setting up the SAGDesign test was to give an accurate way to calculate total grinding energy. Part of this calculation relates to the empirically known reduction of SAG energy by pre-crushing. SAG energy is reduced by 5% for each 25.4 mm reduction in the F 80
Now the maximum capacity of SAG mills reached to 5000 t/h or 35-37 million t/y. But unfortunately (or fortunately) this maximum achieved by pre-crushing. The secondary crusher has additional provisions: increased nu ball mills, increasing the size of balls in SAG mill, increasing ball load in SAG mill, etc.
Bond/Barratt Specific Energy Consumption SABC Model. This is a SAG or AG mill plus ball mill model that estimates the overall circuit specific energy consumption using the classical Bond work index equation for multi-stage crushing and single-stage ball milling (E ssbm) including Rowland efficiency factors.The circuit E total is equal to the E ssbm plus an …

SAG mill vs Ball mill Crushing ratio. 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 SGI equation uses a transfer size between a SAG and ball mill; it is proposed that a synthetic transfer size of 2100 µm be used to model single-stage SAG mills. 5.9ˇ √˙˝ ˛ . ˚ 0.96 0.985˜ !"# ˝ $ ˝ √˙˝ %&'() (2) where: SGI is the SAG Grindability Index, minutes, P80 is the SAG hydrocyclone overflow 80% passing size, µm
SAG mills are also an optimum solution for wet grinding since crushing and screening in these cases can be difficult, if not impossible. Efficiency through automatic operation Outotec's process engineers will assist you in creating an efficient software-driven process, from circuit design to start-up and optimization, to ensure you get ...
Up to 4 million tonnes per year of nickel ore will be treated in a SAG – ball milling circuit with pebble crushing, flash flotation and nickel flotation. Final concentrate, at a grade of between 24 per cent and 30 per cent nickel, will be thickened and filtered in …
Where HPGR technology has replaced traditional methods of crushing and grinding such as SAG or ball mills, customers have seen energy savings of up to 40%, and substantially improved mineral liberation. Find out more about the Enduron …

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. Rock is ground by the turning action of the mill, and impact from the hardened steel balls and the rock itself.
Comminution circuits have progressed from circuits comprising simple crushing machines, for example stamp batteries, through multi-stage crushing and staged grinding, to single stage crushing and semi-autogenous grinding (SAG) and ball mill (SAB) circuits. This progression has, not necessarily, been accompanied by an
SAG mill and ball mill is combined and diluted to 75% solids prior to pumping. The cyclones classify the ground slurry with the cyclone overflow reporting to a trash screen ahead of the downstream circuit. The cyclone underflow gravitates to the ball mill for further size reduction.
Grinding Ball Fragments in the milling circuit impact on two critical areas. One is the crushing circuit where companies have observed damage to crushers, unscheduled downtime and loss of production. The other is the grinding circuit where companies have discovered wear to pumps, sumps, piping, hydrocyclones, mill liners as well as inefficient
