As a result, mines have shifted their emphasis in optimization from ball mills to SAG mills. The rock load in the mill essentially depends on ore characteristics and the discharge rate of broken particles through the discharge end. The discharge rate depends on how efficiently the discharge pump (grate and pulp lifters) operates.

Its unique features to reduce running costs and to become the best choice for equipment. a Sag Mill in China: China is a big country, and could produce a sag mill every year, a large number of quality product is produced and sold around the world. The quality of a sag mill produced in China is guaranteed, and the price is relatively cheap.

The SAG mill (AG mill) has a large diameter and a small length. It looks like a flat round drum. The diameter of the SAG mill is generally about three times its length. The diameter of the hollow pivots at both ends of the barrel of a SAG mill is large. This SAG mill design can facilitate large-sized materials to enter the barrel smoothly.

SAG Mill Ball Charge The SAG mill was simulated to require a 10-12% ball charge with a top size of 125mm. During the commissioning phase no balls were required to be added to the SAG mill to achieve the target throughput of 575tph. This allows for great flexibility in the future and significant security for the future.

In the case of autogenous (AG) and semi-autogenous (SAG) mills this has provided a significant challenge to modellers, due in part to the interaction between feed characteristics and mill ...

SAG mill. SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.

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.

A series of on-site experimental data were collected to examine the SAG mill characteristics corresponding to different grinding conditions. The data acquisition was carried out for cases when any change of the mill operation condition such as the load was applied.

The modeling and simulation of semiautogenous (SAG) mills have been widely used in the design and optimization of mill performance in terms of its power draw, processing capacity and product size distribution. However, these models are solved under steady approximation and do not provide any information on mill charge distribution in real time. This …

SAG Mill Official Feed The Beast Wiki. Feb 12, 2020· The SAG Mill is a machine added by Ender IO.It uses Micro Infinity (µI) to grind (or mill) items into their crushed variants, like Ores into Dusts.The SAG Mill has four output slots; recipes can have 1-4 different outputs, with different chances of obtaining those outputs.

directions, and SAG mill of phase 2 uses two 3700 kW synchronous motors and works with variable speed in two directions. Since this research work was carried out with the objective of changing shell liners of the SAG mill of phase 2, some important characteristics of this mill are summarized in Table 1.

Porphyry Copper Ore in the Barmac VSI and SAG mill, Porphyry Copper Ore in the Barmac VSI Many copper concentrators throughout the world have experienced problems associated with capacity The capacity and power consumption of a SAG milling circuit is directly influenced by the size of the feed to the grinding mills and the strength characteristics of the feed material …

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.

SAG Mill. Grinding Solutions offers the following tests for SAG mill testing and/or sizing. JKTech Drop Weight. The JKTech Drop-Weight Test measures the breakage characteristics of an ore for five size fractions in the range of 13 to 63 mm, at various energy inputs (0.1 to 2.5 kWh/t).

Difference Between Sag Mill vs Ball Mill mech4study. Oct 12 2017 · SAG mill make use of steel balls included with some large and hard rocks for grinding These mills utilize the balls in making the large fragments of materials broken into pieces The ball charge of a SAG mill is about 9 to 20This process takes place inside the large rotating drum of SAG mill which is filled with balls …

Table 2: SAG Mill Perfonnance Characteristics During Commissioning I Feed rate Ball load I TotaTd 1 Power draw Vh 1 % k W . Page 238 It can be seen from Table 2 that with 11% balls and a total charge of 20-22% only 475tlh was achieved compared to a design expec- tation of 950tlh.

Optimizing your SAG mill operation International Mining. Mar 21, 2007 As a result, mines have shifted their emphasis in optimization from ball mills to SAG mills. The rock load in the mill essentially depends on ore characteristics and the discharge rate of broken particles through the discharge end.

2.1 SAG mill model The particles fed to the mill are ground in the milling chamber and subsequently downloaded into the discharge zone, where, according to a classification probability, they are either returned to the milling chamber for further grinding or …

Leading the world in ore hardness testing. The SMC Test® is the most widely-used comminution test in the world for AG & SAG Mills, HPGRs and Crushers.

characteristics), and delivers both an increase in throughput and a reduction of variability. INTRODUCTION Originally commissioned as a Fully Autogenous Grinding (FAG) circuit in 1997, preparations to convert the Katinniq Concentrator Mill to SAG had in fact commenced as early as 1999, but were halted owing to alternative process improvements ...

The harder component of the SAG mill feed from the primary crusher, that component with a higher bond work index, will be over represented in the pebble circuit (relative to the mill feed). In many cases the low grade or barren gangue component of the feed will have these characteristics of higher hardness and lower breakability relative to the mineralised …

Optimum ball charge in a SAG mill is a function of many factors. Some are discussed below. For a SAB or SABC circuit In general, the higher the ball charge the higher the throughput (and fine feed helps as well). Of course, you need a bigger ball mill. But, high ball loads mean higher ball consumption in the circuit.

SAG mills have a higher installed power density for a given plant footprint relative to AC mills. With the combination of finer grind and a lower …
