The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...
The purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit. The ratio of reduction through a primary crusher can be up to about 8:1. Feed: ROM up to m. Product: 300mm (for transport) to 200mm (for SAG mill) Feed Rate:

Common sense and best practice show that measuring a client's own ore is the best way to design a SAG mill. 5. Recent project execution practice, and previous Starkey coauthored publications, confirm that some senior designers want to check the sizing of new SAG mill A against the size of SAG mill B, across the road from plant A, and SAG ...
In the current project, Cortez Gold Mines played a key role in facilitating the 26ft SAG mill at Cortez as a test mill for this study. According to plant personnel, there were a number of unscheduled shut downs to repair broken liners and the mill throughput fluctuated depending on ore type. The University team had two softwares, Millsoft and ...
The processing plant was kept on care and maintenance since 2007 and has been operating at a nameplate capacity of since May 2016. The Thunderbox mill employs a conventional crushing, grinding and CIL leaching process for the extraction of gold. It includes a singlestage crusher, a SAG mill and a ball mill along with elution circuits.

Singlestage SAG mills can be very beneficial in reducing capital costs for plants with a staged throughput approach, according to FL, which markets the FullerTraylor line of SAG mills that range from 14 to 40feet (ft) in diameter. When future tonnage needs to be increased, the SAG Mill can feed downstream ball mills to boost capacity.
Abstract An analysis of flowsheets for processing sulfide and oxide copper ores, reagent modes, processing equipment, and flotation indicators in some domestic and foreign processing plants and productions is carried out. Autogenous and semiautogenous mills are commonly used in the primary grinding stage in ore processing plants, which excludes medium and fine crushing. The alternative is high ...

Despite the differences in scale between the 450 mm test and the m pilot plant tests (along with differing circuit closing sizes, and varying pilotplant operating conditions), the similarity in distributions of unit power requirements reinforces the concept that SAG throughput is defined by a specific unit power requirement.. 3. Drilling and Blasting
The SAG mill is unusual, with a low aspect ratio similar to the ball mills. The ball mills currently produce a final grind size of P 80 of 75 microns (µm). Pustynnoye Gold Mine plans to increase the throughput from to Mt/a and possibly more in future expansions. In order to deliver this capacity increase, management initiated a drill ...
