SAG Mill Components. Once the basic operating conditions have been defined for the mill designer then, and only then, can he begin taking into account shell and head stresses and trunnion bearing sizes required to carry the load and to give the required openings for feeding and discharging the mills. Mill heads are key structural components …
Understand the Difference Between Ball Mill vs SAG Mill. In conclusion, ball mills and SAG mills are both essential in the operation of any mineral processing facility. They both reduce particles in size by using different sizes of grinding media, and have differences in cost, efficiency, and use in regards to application.
The methods on how to manage the changing variables around SAG mills have improved over the years with new instrumentation and Advanced Process Control () systems. Despite these improvements, there is a gap between the available technologies and achieving the maximum potential of the SAG mill performance. The gap traditionally …
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.
As a result of this work, S&A recommended the selection of a 24 ft diameter by 14 ft EGL single stage SAG mill (4.6 MW installed power) to produce 3,000 mtpd. The circuit was to be expanded in later mine life through the addition of an 18 ft diameter by 29.5 ft ball mill (also 4.6 MW installed power) in order to double the throughput. KEYWORDS
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
The ball mill work index is determined from Bond's Third Theory of Comminution: Where: The SAG mill pinion energy, W SDT (kWh/t) and SAG discharge Bond ball mill work index, S d -BWI (kWh/t), are then used to calculate the total energy to grind the ore from 80% passing 152 mm to 80% passing the client specified final product size P 80.

An optimization is carried out to minimize the yearly cost of energy for the operation of the SAG mill. This cost includes the energy consumption cost in $/kWh and the capital cost for the PV-BESS infrastructure, prorated over the life of the battery system, accounting for the discount rate through an annuity factor (Pamparana et al. 2019a, …

Autogenous grinding is favored when the ore is quite competent and a fine grind is required. Semi-autogenous grinding is applied when fine crushing could cause severe problems or when ore is variable in hardness or competency. Figure 2 shows a typical conventional crushing-grinding circuit with three stages of crushing followed by …
38′ X 22′ EGL GRATE DISCHARGE SAG MILL, 26,000 HP. Siemens 26,000 HP (19.4 MW) Gearless Wrap Around Drive Motor. Mill was ordered but …
This result is similar to the result presented in Dreher et al. (2004) for a 38 ft SAG mill. Measured stresses ranges at the head for that mill agree with calculated stress ranges within 6% but the measured stress ranges in the shell of that mill are, on average, approximately 30% lower than the calculated stress ranges.
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 …
Whereas 30 years ago the rule of thumb for designing AG/SAG-Ball mill circuits was to split the total installed motor capacity 50:50 between the AG/SAG and ball mill circuits, Tozlu and Fresko's ...
When SAG mill liner bolts loosen, break or stretch beyond limits, liner impairment and degraded performance are generally next on the agenda, followed by mill stoppage for repair or replacement. Bolts and nuts — among the smallest mechanical components used in grinding mills — play a big role in ensuring whether a mill can be efficiently ...
The internal belly length was, therefore, increased to give a mill aspect ratio of 36 ft × 16 ft (EGL), which matches a 12,680 kW mill [41]. A direct geometric scale-up would have a length ...
Maximum t/h limit is a t/h throughput above which the SAG and ball mills will turn down by, for example, grinding out. T80 min and T80 min override the transfer size restrictions built into the model. Ball mill work index adjustment used to adjust Wi BM for different P 80 sizes. coefficient (a), the fitted coefficient to the adjustment equation.

Traditionally, the number of shell lifters used in a SAG mill is equal to twice the number of the feet in the mill shell diameter (e.g., a 34-ft-diameter mill shell would have 68 shell lifters). This is also called a 2-D shell lining. Eliminating some shell lifters increases the volume of charge between the lifters
1. If the SAG mill is too small, capital revisions will be required. Either pre-crushing, pebble crushing or both may be required. Operating costs will also be higher due to higher steel load required and/or higher mill speed which can be …
