The IsaMill usually consists of a series of eight disks mounted on a rotating shaft inside a cylindrical shell (see Figure 2). The mill is 70–80% filled with the grinding medium, and is operated under a pressure of 100 to 200 kilopascals. The disks contain slots to allow the ore slurry to pass from the feed end to the discharge end (see Figure 3).
This makes the use of standard ball mill analyses based on the K80 inadequate, unless appropriate corrections are made. (This problem is shared by AG/SAG mill circuits.) The most appropriate way to get around this data problem is to run the entire circuit at pilotscale and analyze the data based on the overall power applied in kWh/t.

The mill was successfully commissioned between March and May of 2017 and reached full operation in Q4 2017. In 2018, various review and assessment work was conducted to evaluate the potential of increasing mill throughput to 3,800 t/d and potential bottlenecks that may limit a further increase in the mill feed .
Ball mill is mainly used for grinding in mining (metallic minerals and nonmetallic minerals), cement, refractories, chemical, power plant, aluminum,building material, glass, ceramic, steel slag and fly ash, ect. It follows more crushing and less grinding principle to save energy. The feed size to ball mill shall be smaller than 25mm, the output size can be adjusted by revising steel balls ratio.

This technique offers new opportunities for barren pebbles rejection from the AG/SAG mill pebble stream, coarse waste rejection at mine site to reduce the RoM haulage, pretreatment of AG/SAG mill feed taking the combined advantages of preweakening and preconcentration, and multigrade comminution and recovery circuits.
Independence said it is rectifying the situation: "The SAG mill liners are currently being replaced in a planned processing plant shutdown and are not expected to affect availability or productivity going forward." Even with this setback, the company produced 7,344t of nickel metal in the June quarter, up 23% from the March quarter.
The Coalition for Energy Efficient Comminution (CEEC) has been established and is supported by a broad range of mining sector companies keen to accelerate awareness, knowledge transfer and, by implication, improve energy and cost outcomes in the substantive area of comminution.
The collected SAG feed sample was prepared for pilotscale HPGR and stirred mill testing to determine the key operating parameters for flowsheet design and powerbased calculations. Ultimately, the simulation and test results allowed for the direct comparison of the energy and costs for three circuits.

This design of SAG mill feed chute lasted 9 months seeing 90,000 TPD. It is 600 brinell chrome steel. With the big liners on the bottom of the chute you need to get a Chevron cast into the top to push the feed out to the sides for the first little while and then as the chevron wears it will start to come back
