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 …
SAG mill control fundamentally means managing the load in the mill by adjusting the feed rate of ore to the mill and/or manipulating the rotational speed of the mill. The best way to measure load is to mount the mill on load cells. The load cells are calibrated to measure the total weight of water, grinding media (balls) and ore in the mill ...
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 ...

The amount of pebbles passing through the grate increases with the angle of the grate. It is imperative to ensure the efficient removal of both slurry and coarse pebbles (critical size) in order to ensure the efficient operation of AG/SAG mills. Elimination of the above mentioned material transport problems will allow the mill to respond truly ...
Working Principle of a Thyristor. In a thyristor, the silicon wafer is doped with four alternate P and N types, which looks like two transistors connected back-to-back (as seen in the pic below). Here, the P (cathode) and the N (anode) are joined in series, thus we get three terminal pins: anode, gate and cathode.
The sag and the under voltage can be generated by voltage drop across a reactor, while its magnitude and durations can be controlled by the firing angle of TCR (thyristor controlled reactor). In the case of the swell and the over voltage, we need a step-up transformer. Output of the step-up transformer is regulated by TCR to obtain nominal ...
Examples of SAG mill in a sentence. It includes single stage jaw crushing with reclaim from a live stockpile and open circuit SAG mill, feeding cyclones that in turn operate in a closed circuit with a ball mill.. A pebble crusher will receive scats from the SAG mill, crush them and return them to the SAG for further grinding.. The process will include a conventional single-line SAG mill ...
SCR or Thyristor is a four-layered, three-junction semiconductor switching device. It has three terminals anode, cathode, and gate. Thyristor is also a unidirectional device like a diode, which means it flows current only in …

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. Amstar 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 ...
The 38' SAG Mill at Freeport Indonesia has already proven discharge capacity at new feed rates of over 6,000 mtph. The largest mill line offered to date (2004) includes a 33,000 HP (24.6MW) SAG Mill and two 25,000 HP (18.6MW) Ball Mills for a total installed power of 83,000 HP/61.8MW. This list speaks for itself.
This distribution affects the SAG mill load and the load affects directly the mill power and the efficiency of the mill operation (Van Nierop and Moys, 2001). If a SAG mill has been designed with a conventional power or specific energy model which do not consider the projected feed size distribution it is likely that this mill will reach the ...
SAG Mill Design and Specification . The Kidston plant was designed to process 7500 tpd fresh ore of average hardness; but to optimise profit during the first two years of operation when softer oxide ore will be treated, the process equipment was sized to handle a throughput of up to 14 000 tpd. Some of the equipment, therefore, will become ...
In the SAG mill, the collisions with large energy acting on the ore mainly occur in the toe area, where the dropped steel balls and ore with high kinetic energy hit the ore and liner. As shown in Fig. 12c, the collision frequency between ore-ore and ore-media in the SP grinding system is similar in Range C (> 0.6 J). However, in the PH-SP ...
Variable Speed Drives. Variable speed drives are not new. Many have been used in the cement industry on mills drawing up to 6,525 kW (8,750 hp). There are 39 gearless drive installations worldwide, but only one in North …
A control strategy recently implemented on a large variable-speed SAG mill at MMG's Century Zinc operation in Australia is shown in the chart (found on pg. 32). In this case, mill speed is the primary manipulated variable used to control mill load. While there is no generic control strategy for SAG milling there is a considerable amount of ...

Control of -SemiAutogenous Grinding(SAG) mill weight is an example of an important process that exhibits many of these aspects. Maintaining the SAG mill weight at the optimum value is critical for achieving maximum grind rate efficiency and mill production (Powell, M.S., van der Westhuizen, A.P., & Mainza, A.N. 2009).

Features. Semi-autogenous Metso Outotec SAG mills, as they are often called, can accomplish the same size reduction work as two or three stages of crushing and screening. Often used in grinding at modern mineral processing plants, SAG mills reduce the material directly to the desired final size or prepare it for the following grinding stages.

These studies have been important in a coordinated optimization program for mill heads, shells and trunnion bearings. Mill Shells require a similar but more complicated program for stress and deflection analysis. Often, depending on the load concentration and mill length, special shell designs are required. An example is shown on Figure 5.
