Keep Reading8.1 Grinding 8.1.1 Grinding action Industrial grinding machines used in the mineral processing industries are mostly of the tumbling mill type. These mills exist in a variety of types - rod, ball, pebble autogenous and semi-autogenous. The grinding action is induced by relative motion between the particles of media - the rods, balls or pebbles ...

Keep ReadingFig. 2 shows the flotation results of the spodumene ground by ball and rod medium, respectively, as a function of the pH using 0.2 mM NaOL/DDA (with a molar ratio of 6:1) solution as collector. As seen in Fig. 2, with the increase in the pH, the recovery of both the ball and rod milled spodumene peaked at pH −8, which is attribute to the significant increase in the concentration of …

Keep ReadingBond Rod Mill Grindability Test. Grinding Solutions can carry out Bond Rod Mill Work Index tests to determine the energy requirements for milling ore in a rod mill. The test requires a minimum of 20kg of -12.5mm material. Closing screen sizes typically range from 4.75mm to 212µm. Abrasion Index Test

Keep ReadingThe classical method used to predict the specific energy consumption in grinding ores in rod mills was proposed by Fred Bond and is based on the work index (Bergstrom, 1985). The Bond rod mill work index (Wir) is measured using Bond´s standard rod mill grindability test, which is conducted in locked-cycle mode to emulate the continuous closed ...

Keep ReadingThe rod mill work index laboratory test is conducted by grinding an ore sample prepared to 80% passing 12.7 mm (½ inch, the original test being developed in imperial units) to a product size of approximately 1 mm (in the original and still the standard, 14 mesh; see Chapter 4 for definition of mesh), thus determining the rod mill work index ...

Keep ReadingRod mills are limited in size to 2000 kW because the longest commercial grinding rod available is 6 m long. For this reason rod mills are rarely selected in the present day environment of large AG/SAG mills and large ball mills. However, it is necessary to discuss their operation because a Rod mill product has a similar slope to AG/SAG mills.

Keep ReadingRod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a high-carbon steel, can vary in both the length and the diameter. However, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency [5]
