In June 1998, the world's largest grinding mill, the 40 ft (12.2 m) diameter 20 MW Cadia gearless SAG mill, was commissioned. This was a leap of over 40% above the largest operating SAG mill. A significant saving in capital cost gave the incentive necessary for a single mill line at Cadia, resulting in the selection of the 40 ft (12.2 m ...

A SAG mill, or semi-autogenous grinding mill, operates on the principle of autogenous or self-grinding. It uses a combination of ore and grinding media to break down larger rocks into smaller pieces. Understanding the working principles of a SAG mill is crucial for anyone involved in the mining industry. In this section, we will delve deeper ...

In normal operation the SAG Mill is fed with predominantly HPGR product and 10% to 15%. fresh feed fro m the primary feed bin (actually a combination of RoM …

for the Cadia Hill SAG mill circuit, throughput increased by increasing the SAG mill ball charge, reducing the number of lifter rows, reducing the rock charge, and reducing the SAG mill feed size distribution from an average F80 of 100mm to 80mm. These research efforts present interesting findings for increasing mill throughput while also

As the SAG model in JKSimMet does not take account of the variation in breakage rates at different mill loads, the SAG mill load for different A and b values (Table 5) is kept the same as in the base case (Table 4). Simulated throughput was compared with the base case and the results are presented in Table 6, Table 7).

1 Fresh feed to SAG mill is only the Coarse feed from the primary bin feeder, total feed to the SAG mill is fresh feed plus HPGR centre product. The HPGR easily processes the nearly 2,500 t/h of ...

The JKMRC mill filling soft sensor (JK MillFIT) utilises mill power draw and mill load (bearing pressure or load cell), which are measured in real time, and integrates models developed for mill ...

The SAG mill operated to 97% of installed motorpower, for an annual throughput of 22.5 million tonnes per annum (Mt/a) in the 2019 fiscal year.In 2019 the site metallurgy team endeavoured to operationally de-constrain the SAG mill to lift the nominalprocessing rate of Concentrator 1 with minimal capital expenditure.

Ø SAG mill availability was lower than expected in the first year due to issues with the gearless drive and trommel panel failures. Figure 1 shows the ramp up of the Cadia Hill SAG mill by quarter.

Air Gap Sensor. The Air Gap Sensor DPA series is a pneumatic, high precision sensor capable of "checking the adhesion" between the workpiece and the jig. If air is available, you can check not only "presence/absence" but also "adhesion (gap)" at the same time with a repeatability of ±0.5μm. Prevents processing defects and equipment downtime ...

AG mills (or SAG mills with low ball charges) are often used in single-stage grinding applications. Based on their higher throughput and coarser grind relative to AG mills, it is more common for SAG mills to he used as the primary stage of grinding, followed by a second stage of milling. AG/SAG circuits producing a fine grind (particularly ...

The Concentrator 1 plant at Cadia transitioned from Cadia Hill open pit to the Cadia East block cave ore body in 2013. As a result of this change, major plant upgrades were required to achieve the desired throughput while treating more competent ore. The 40-foot (40') SAG mill now receives a feed of predominantly high pressure grinding rolls (HPGR) product …
