Oct 12, 2017 The ball charge of a SAG mill is about 29% to 30%. By friction and influence of tumbling balls inside rotating cylinder grinds the raw material to the required fineness. The internal machinery of ball mill grinds the raw material into the powder-like material, And if extreme fineness and refinery are required then rotation go on continue.

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%. [6] [7] The largest SAG mill is 42′ (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor. [8] A SAG mill with a 44

Jacking/Lifting Cradle The mine is closed and now you need to know how to put the SAG or Large Ball Mill in care and maintenance does not have to be complicated to the point where you need bridge erection equipment for lifting a Mill (AG/SAG/Rod/Ball). You actually need

Both the autogenous grinding mill and the ball mill feed parts are welded with groove and embedded inner wear-resistant lining plate. As the sag mill does not contain grinding medium, the abrasion and impact on the equipment are relatively small. The feed of the ball mill contains grinding balls.

I’m looking for ideas to process the discarded material of a SAG mill. We have huge material stocks of this process that contains ore contaminated with metal balls and some scrap elements that makes it hard to process it on a crusher. I have seen a small company that almost manually clean up the d

SAG milling extends itself to many applications due to the range of mill sizes available. They can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill and some or all of the work done by a ball mill. SAG mills are also an optimum solution for wet grinding since crushing and screening in these

Dec 21, 2016 2 parallel SAG Mills each feeding 2 parallel Ball Mills (4 total). Around 50,000 TPD total grinding circuit capacity.

Attrition mill is a type of grinding mill by kinds of media to crush lump to powder-like substances. The impact can be rock on rock such as in an Autogenous Grinding (AG) mill, rock and a small ball charge (~10%), used in Semi Autogenous Grinding (SAG) mills, balls of various sizes in Ball Mills and less commonly these days, steel rods in Rod Mills.

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.

Flowsheet Sag Mill Dan Ball Mill In Egypt. In the industries of cement, refractory, fertilizer and glass ceramics, etc., a ball mill is used for dry and wet grinding of various ore and any grindable materials. Mining Machinery Specializing in the production of jaw crusher, sand machine, ball mill, Raymond mill, cement equipment and other

The ball diameter is smaller than that of horizontal ball mill. Glass balls or ceramic balls (such as vertical ceramic ball mill ) can also be used according to the grinding requirements. For the case where the finished product has special purity, the grinding medium can also be the raw material with a larger size (such as SAG mill ).

For example, the SAG mill may have 10 MW of power draw available and the two ball mills each of 7.5 MW of power draw available for a total of ratio of 10:15 (1:1.5). The software uses the particular power model (Bond/Barratt, Morrell Mi, etc.) to determine what is the transfer size where the ratio of E SAG to E ball matches the ratio of mill

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 s) including Rowland efficiency factors.The circuit E total is equal to the E s plus an inefficiency factor (CF) related to

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
