Modern, large SAG mills are major capital- cost items with price tags reaching well into the eight-figure dollar range. They stand at the entry point to a variety of comminution circuit setups and when they stop for whatever reason, the revenue losses per circuit mount quickly.

The Robinson Sag Mill & Concentrator is a silver, gold, and copper mine located in White Pine county, Nevada at an elevation of 7,054 feet. About the MRDS Data: All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy.

includes a Bond Ball Mill Work Index test on SAG ground ore from the first stage of the test. The ratio of SAG pinion energy to Bond BM Wi is a key parameter in a SAG mill grinding circuit design, because this ratio controls the power split between SAG and ball mills at the target T80 transfer size( ). INTRODUCTION

The target was set at two months to equal the current wear life the mine site was getting. PRI worked closely with the customer to develop a design that would help decrease their downtime on their 34' diameter by 17' long SAG mill. The cone supplied with PRI ceramic Matrix technology lasted over 12 months! This also led to more business at ...

Presently SAG mills are mainly driven with variable speed drives, allowing the operator to react easily to the changes in ore characteristic and throughput. Ball mills on the other hand, as far as process requirements are concerned, did not …

The Gol-E-Gohar iron ore concentration plant located in southeast Iran. Three 9 m × 2.05 m AG mills are used in parallel in a dry operation to grind a feed nominally passing 32 cm, which is the product of a gyratory crusher.The SAG mills is driven by a 4023 hp motor and runs at a constant (12 rpm rotational) speed (i.e., 85% of critical speed) in one direction.

AG/SAG mills, circuit design, plant performance, optimization INTRODUCTION AG or SAG mills have been in use in comminution circuits since the 1950's and are considered a mature technology in most countries. However, a reasonable number of recent SAG mill based projects

operating SAG mills in Australian and Chile using sensors inserted into grinding media and sensors fixed to the rotating mill shell. The dynamics of the operating mill are so complex that modelling and test work falls short of providing reliable actionable insight for operators and mill practitioners. We propose that a critical

The SAG milling of ores with markedly variable grinding rates presents definite process control challenges. Decisions must be made regarding the selection of the most appropriate combination of mill volumetric load level, …

Average of difference between Current draw for both drives is 20 (A) in case of forward rotation with standard deviation about 22 (A). As you can understand from high standard deviation, the difference is not consistent but in 93 % of operation times, drive number 2 draw more current in both forward and reverse rotation.

Differences between drives power draw of two drives sag mills. In a double drive/pinion SAG, we face different power draw between each drives. Can this be caused by charge motion or some others process problem?

Accordingly, the mill power consumption decreased from 8.4 to 5.16 kWh/t (a nearly 40% reduction), and the fresh feed flow rate increased from 515 to 615 t/h (a nearly 20% increase in the mill ...

Ball Mill Wi test on SAG ground ore from the first or SAG stage of the test. The SAG stage therefore had to use enough material to do the Bond Wi test. To ensure this, the SAGDesign SAG mill was designed to be 488 mm (19.2") in diameter and 163 mm (6.4") long (EGL). Other design parameters for the SAGDesign SAG mill were selected to
