The grinding circuit consists of a conventional SAB circuit with a 7.93m x 3.73 m 3,356 kW SAG mill and a 5.49 m x 8.84 m 4,474 kW ball mill in closed circuit with 6 hydrocyclones (4 operating and 2 on standby). SAG mill throughput typically ranges from 473 -.
For the mining industry, our semi-autogenous (SAG) grinding mill uses a minimal ball charge in the range of 6-15 percent. It is primarily used in the gold, copper and platinum industries as well as in the lead, zinc, silver, and nickel industries. Autogenous (AG) grinding mills involve no grinding media as the ore itself acts as the grinding media.

Read MoreSAG mill. SAG is an acronym for Semi-Autogenous Grinding. SAG mills are autogenous mills but 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.
Read MoreAfter the initial comminution stages of crushing and or SAG AG milling, the following grinding stages is usually carried out using steel charged ball or tower mills. The impact of grinding using steel media can offset any benefits gained by improved liberation, particularly as the target size decreases below 25 m.

It also marked the completion of a mill expansion. At the same time, a continuous method of measuring the charge volume in the semi-autogenous grinding (SAG) was developed.
Read MoreJan 01, 2021 1. Introduction. Mill filling has a dominant effect on grinding mill performance (Apelt, Asprey and Thornhill, 2001), and therefore, its accurate measurement is vital for modelling grinding mill performance.Measuring filling is also necessary to estimate the composition of the load for mill modelling rock and slurry for AG mills rock, balls and slurry for SAG mills or balls and slurry for.
Read MoreDec 31, 1995 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. Considering a typical mining operation processes 10,000 to 100,000 tons per day the energy expenditure in grinding is 50 percent of the.
