Product Size: All passing 6 mesh with 80% passing 20 mesh. Net power from pilot plant: 16.5 KWH/ST. Mill, gear and pinion friction multiplier: 1.025. Mill Power required at pinionshaft = (240 x 16.5 x 1.025) ÷ 0.746 = 5440 Hp. Speed reducer efficiency: 98%. 5440 Hp ÷ 0.98 = 5550 HP (required minimum motor output power).

1. SAG mill is the primary tool for grinding. SAG mill is used before the other mills. Ball mill is a secondary, and it is used after the SAG mill. 2. SAG mill breaks the raw material into pieces for the further grinding. Ball mill is used to grind the pieces of raw material into. powder-like structures. 3.
A typical shape of the 3-D model of a worn liner after 5384 h of operation is shown in Fig. 2. This shape has been obtained by taking six measurements (profiles) with …
four simulation tasks, consisting of AG, SAG and ball mills are reported. The simulation of AG and SAG mills are completed in less than 8 hours. The ball mill simulation with 1.25 million spheres is completed in 27 hours. In the near future, these compute times can be halved with the advances in graphic card hardware. KEYWORDS
Fuller-Traylor SAG/AG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW. Our team of product engineers continually improves SAG/AG Mill …
Analysis of typical SAG mill installations in the copper industry indicates that typically less than 90% of installed motor power is used on average. Therefore, the installed SAG motor power was determined to be 9.72 kWh/t (8.75/90%). Checks were carried out to ensure that the SAG mill could utilise this power within a reasonable envelope of ...
In modern mineral processing, semi-autogenous (SAG) mills are important grinding equipment. A SAG mill has the advantages of high operation rate, large output, and large crushing ratio, which makes SAG …
SAG Mill - Semi-Autogenous Grinding Mill. A semi-autogenous grinding mill, or Sag mill, is responsible for grinding materials from large chunks into small, usable pieces for processing. The Sag mill …
Single stage SAG Mills are very beneficial in reducing CAPEX for plants with a staged throughput approach. When future tonnage is to be increased, the SAG Mill can feed downstream ball milling to boost capacity. Fuller-Traylor SAG/AG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW.
Section snippets Model validation. To test the validity of the model data from 21 different full-scale AG/SAG mill circuits were used. The data comprised mill dimensions, grate design, mill speed, throughput, feed size distribution, product size distribution, power draw, ball load, ball size, normal operating load level and rock breakage characteristics …
Sag mill - files. The CAD files and renderings posted to this website are created, uploaded and managed by third-party community members.
Introduction. SAG (semi-autogenous grinding mills) are large cylindrical chambers with conical ends, that are partially filled with rock and steel grinding media, and which rotate about their central axis at typically 75–82% of the critical speed required to centrifuge the charge.
SAG mill is an investment that can produce handsome returns if extra production is needed or simply to give the mine the option to mill the hardest ores at design throughput rates. Typical tests required to define a hardness variability function, are given below in Figure 1. The
At Growth Rubber we know the importance of an optimized Mill Liner design. That is why we utilize the latest design and simulation software to ensure your Mill Liner System will provide optimal grinding performance at the lowest operational cost.

Ball mill： Ball mills are the most widely used one. Rod mill： The rod mill has the highest efficiency when the feed size is <30mm and the discharge size is about 3mm with uniform particle size and light …
Ball mills with two different sizes were considered in this study, one small and another large. The simulations with the two mills have the same conditions as the real ones by Valderrama et al. (1996) and Kalala and Moys (2004), respectively, in terms of mill size, particle size, mill speed fraction (mill speed as a fraction of critical speed) and fill level …
mentioned some case studies of using good liner designs. For example, the initial SAG mill liner was installed using Hi-Hi with a 6. o . contact angle. Mill throughput increased by 11% after the face angle had been altered to a 17. o. angle and then to a 30. o. angle. Currently, the large face angle (typically 20. o . up to 30. o
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 ...

5 to 50 TPH SAG Mill. Starting as small as 13 feet (4 m) in diameter on 330 HP and as large as 24′ (14.5 m) in diameter on 3,300 HP, the 911MPE Semi & Fully Autogenous Mills tumble crushed ore without iron or steel grinding media. They are used when the crushed ore pieces are hard enough to perform all the grinding.
