The ore pretreatment flow charts in use at most high productive processing plants designed in the last decade are based on semiautogenous (SAG) milling and involve as a rule primary wet autogenous mill (WAM) and a series of ball mills. WAM is customary chosen either based on examination of analogous equipment

Nov 11, 2015 The SPI/SAGdesign methods. Each methodology involves a series of grindability laboratory tests and a suite of equations used for mill power and throughput predictions. This presentation deals only with the Bond work index suite. The desired outcome of all of these methods is an estimate of the grinding

ABSTRACT. Mill filling is an important operational parameter in a SAG mill circuit and by its control and optimisation it can produce significant improvements in production capacity and energy efficiency. However, it is industry practice to report mill load as the total output given by load cells, or kPa for systems based on

A great deal of effort has been expended in the last 11 years by the authors and others to identify the correct power required to grind ore in a SAG mill, by developing ore hardness variability functions for the ore body to be mined. This paper describes the next step in the SAG design process, which is choosing a SAG mill to

Optimisation of milling needs a systematic approach. One has to ensure the stable operation of the milling circuit before you can aim to optimise power input. Bear in mind that SAG and Ball mills are the highest power consuming equipment in the plant. All Mineral Processing plants have some form of comminution, but SAG

that a slightly more expensive 42 ft SAG mill with equivalent power to the 40 ft SAG mill enhanced the project economics. After assessing the potential reliability difference between the 40 ft SAG mill and the equivalently powered 42 ft SAG mill, Newmont made the decision in 2010 to purchase a 42 ft SAG mill from and

SAG mill control is essentially the stabilisation of mill load (and/or power) and density which can be implemented successfully and very costeffectively on most modern PLC or DCS platforms.

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

The paper summarizes the current state of development of simulation models for SAG and FAG mills, and gives the results of recent investigations of the physical processes occurring in autogenous grinding. The breakage process is treated as the sum of three regions of breakage actions: normal breakage caused by

This increased efficiency and utilised more installed SAG mill power. The cyclone operation was changed to constant pressure and the vortex finder size was decreased
