The amount of sample that is required depends on what sources are available to provide the rock samples eg, is it drill core, what size of core is it, is it whole, halved or quartered as well as the size fraction ...

Similar to the impeller design affecting pump capacity, the pulp lifter design affects the discharge capacity (or mill throughput) of AG and SAG grinding mills. Generally, the discharge from AG/SAG mills consists of one or both of the following components: slurry (water and finer particles) and pebbles (20-100 mm).

Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.

Larger ball and SAG mills, with higher installed power ratings relative to the mill diameter, offer higher efficiency and throughput, round-the-clock reliability and the opportunity to mine in remote areas. ... Feed-forward data on ore quality and quantity, rock face production rates or market demand rates can be used to optimize the grinding ...

As mentioned, the SAG mill is a first stage mill grinder and often operates as the "stage one" in a 2-3 step process of milling materials. Without the SAG mills initial grinding of materials, other mills would simply become incapable of completing their required task. Have a browse through our available range of used SAG mills for sale.

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 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...

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 hours, days or weeks needed to get a mill back on line are often ...

Based on experience, mill-liner designs have moved toward more open-shell lifter spacing, increased pulp lifter volumetric capacity, and a grate design to facilitate maximizing both pebble-crushing circuit utilization and SAG mill capacity. As a guideline, mill throughput is maximized with shell lifters between ratios of 2.5:1 and 5.0:1.

The SAG mills have been mostly used for milling hard gold and copper ores with quartz, ultramafic or green stone as host rocks. The Bond work index of these ores ranges between 12 and 14 kWh/t. Subsequently, SAG mill application has been extended to softer ores, such as bauxite and clayey hard-capped gold ores.

The Ball and SAG mill shells were recently delivered, and are now being assembled and prepared for installation. The Company expects delivery of remaining mill components such as the motors in the ...

The Integrated JK Drop Weight Test provides ore specific comminution parameters that are used in the JKSimMet software to analyse and/or predict crusher and AG/SAG mill performance. This allows for optimisation of current circuits or flowsheet design for new circuits. Developed at JKTech, the Integrated JK Drop Weight & SMC Test is a single ...

In the second generation, SAG mills re-placed the second and third stages of the crushing system and also the primary mills. Example configuration for the second generation. ... erial, as well as the gas quantity needed for ventilating the mill, are extracted via the

SAG mills of comparable size but containing say 10% ball charge (in addition to the rocks), normally, operate between 70 and 75% of the critical speed. Dry Aerofall mills are run at about 85% of the critical speed. The breakage of particles depends on the speed of rotation.

The application. Industrial milling of mined ore – from large rocks and boulders to fine particles – is a demanding process. Massive semiautogenous mills – commonly known as SAG mills – use milling balls, as well as the weight of the ore itself, to break down the ore into smaller particles – a process known as comminution.

Interesting, as in a recent article in Mining Magazine (July/August 2014, pp. 27), Kurt O'Bryan of Weir Minerals says that, although SAG mills have been around for over 40 years, the demand to process more ore in less time is a key factor in where comminution trends are heading. He says that "SAG mills have to be bigger to meet these demands.

At Ok Tedi, ore type and SAG feed size distribution vary widely and frequently. This makes control of the SAG mills by application of the power/pressure relationship difficult.
