This was presented at the Procemin-Geomet Conference in Santiago, Chile, in 2019. In a first for industry, this innovative approach aims to collect data from

Mill Operators' Conference 2018

To minimise the onset of slurry pooling, the SAG mill needs run below ~74 % critical speed for the grates with 25 mm aperture. As the mill runs faster, the effective open grate area reduces and limits the slurry flow through the grates. For mill speeds, lower than 74 % critical, the grate flow capacity is greater than the mill inflow of 1,800 m3/h.

12/04/2022The mechanical properties of different growth types of leaf veins are compared and analyzed by the finite element simulation. In addition, the optimality of the adaptive growth law of leaf veins is also analyzed. Then, a parameter optimization method of stiffeners layout based on a variable cross-section structure is proposed.

2.1 SAG mill modeling In MODSIM, one of the simulation models used for a SAG mill unit is SAGT (Semi-Autogenous Grinding with Trommel) model. In this model, a SAG mill with a trommel screen at mill discharge is modeled using the full population balance including particle attrition and wear (King 2001b). In this

the specific power requirements (inclusive of contingencies) for SAG milling (9.72kWh/t) allows the SAG mill motor size to be determined (i.e. 20MW). Selection of SAG mill dimensions and operating parameters is a complex problem and suffice it to say here that it is advisable in the design to provide operating flexibility to increase power demand.

Freeing up milling capacity in a SAG mill ball mill circuit

The throughput capacity and efficiency of a SAG mill are affected by the significant recirculated load derived from over-size discharge product (critical size "pebble" discharge) that is screened out and may be stockpiled or requires secondary crushing prior to re-introduction to the SAG mill feed.

01/06/2005Adjustments to the lifting plates around the circumference of the mill provide greater lift and drop and thus greater efficiency. SAG mills are often used as regrinding mills after a fully autogenous milling. Thus giving them a lower efficiency as they are grinding very small rocks to start with. Also depends on the medium in the mill.
