MILL DENSITY CONTROL RULES The feed water addition to Sag mills is also a very important control variable. There are many approaches that can be used in controlling the water. One way is to use the steady state equation for density in the mill which is shown in the following equation. [ ] [ ] [ ] Rock tons hour Water tons hour Rock tons hour ...

The ball mill work index laboratory test is conducted by grinding an ore sample prepared to passing 3.36 mm (6 mesh) to product size in the range of 45-150 µm ( mesh), thus determining the ball mill work index (Wi B or BWi). The work index calculations across a narrow size range are conducted using the appropriate laboratory work ...

Apr 24, 2014· These higher energy intensity blasts produced even finer Run-of-Mine (ROM) fragmentation and subsequently finer feed to the SAG mill. The SAG feed F80 (the size that 80% of the feed material is smaller than) was reduced to around 50-60 mm compared to 100–120 mm previously, and the percentage of fines (-10mm material) was increased from 25% to ...

These mills are scheduled of start up on 2012. Our market share in China exceeds 80% with the largest mills supplied to date being a Ø7.9m x 13.6m 2x8.5MW Ball Mill and a Ø11m x 5.4m 2x8.5MW SAG Mill, being the largest in China.

Depending on the mill size the SAG mills draws between 2 MW and 17 MW. The product from the SAG mill is further reduced in size using pebble crushers and ball mills. Hence, typical gold or copper ore requires between 2.0 and 7.5 kWh per ton of energy to reduce the particle size.

Prediction of the mill dimensions zThe ball-mill dimensions (internal mill diameter D and length L), for a given (L/D) ratio, for feed size D f and product size d (mm), for a known Bond work index w i (kWh/short ton) and for desirable capacity T (short ton/h), can be calculated from: D d T D D L f 3.5 )0.106 0.193 0.962 10.38 0.9180 ( ) (1 − × =

tion of the mill. Unfortunately, to get what is required, this information needs translation into something that the gear designer can input into the rating calcu-lations. The calculation of actual contact stress s c does not have an input for tons/ hour of mineral produced. A theoretical relation of mill diameter to power is ~ mill diameter2.5 ...

to convert the AG mills to SAG mills. Simulation of the charge trajectory indicated that increasing the liner lifter face angle from 7 to 30° could provide an appropriate charge trajectory in the SAG mode. Installation of the new liners and conversion of AG mill No. 2 to SAG mill…

Depending on the mill size the SAG mills draws between 2 MW and 17 MW. The product from the SAG mill is further reduced in size using pebble crushers and ball mills. Hence, typical gold or copper ore requires between 2.0 and 7.5 kWh per ton of energy to reduce the particle size.

commercial grinding conditions for the test in a 0.5 m diameter SAG mill. In the 2009 database, SAG pinion energies (to grind from F80 152 mm to T80 1.7 mm) vary from 1.4 to 34 kWh/t and Bond ball mill work index values vary from 6 to 24 kW/t for the same ores. Project design tonnages varied from 200 to 150,000 t/d, SAG mill sizes varied from 10 ft

Ball Mill Power Calculation Example #1. A wet grinding ball mill in closed circuit is to be fed 100 TPH of a material with a work index of 15 and a size distribution of 80% passing ¼ inch (6350 microns). The required product size distribution is to be 80% passing 100 mesh (149 microns).

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. A SAG mill with a 44' (13.4m ...
