The SPI™ test is used in the CEET model (Comminution Economic Evaluation Tool) developed by Minnovex and now marketed by SGS. There are two forms of CEET - the older "CEET 1" model is a power-based model that predicts grinding specific energy consumption for a SAG mill (E sag) using a formula with superficial similarity to a Bond equation.

This paper discusses the process design and layout of the Constancia Project comminution circuit. The circuit consists of a 60 x 113 primary crusher, two 16 MW SAG mills and two 16 MW ball mills. All four mills are twin pinion with wound rotor motor and gearbox drives. Provision for pebble crushing is

To compensate for the lower pebble rate the SAG ball load was increased resulting in the total comminution circuit power being some 0.5kWh/t higher than predicted. The JK …

Conducted in a bench-scale comminution mill, the SPI test measures the energy needed to perform a standard size reduction and is expressed as an index. It is a measure of the hardness of the ore from a SAG or AG milling perspective. The test is a batch test, run with 2 kg of ore in a standard 10 cm diameter by 30 cm long mill, and it measures ...

In modern low-grade mining operations, comminution uses energy and other consumables on a scale that is unprecedented. Today, new deposits are being found in more remote areas and are trending toward harder ores and finely grained minerals. These factors have …

The SPI (SAG Power Index) is another related inde x used to determine the ore comminution behavior in AG/SAG mills. The index is obtained from a ba tch test in a mill of 305 mm × 102 mm operated

Jul 30, 2020· The SMC Test®, developed by Dr Steve Morrell of SMC Testing, is a cost-effective means to predict comminution circuit throughput, rock mass characteristics and blasting properties. Energy requirements for crushing and HPGR options can now be determined in addition to AG/SAG mills, and with Mic, ball mills.
