The Bond ball mill work index is one of the most commonly used grindability tests in mining, and is often referred to as the Bond work index.. The test is a 'locked-cycle' test where ground product is removed from test cycles and replaced by fresh feed.

The SAGDesign test was developed to overcome technical limitations of the SPI (Starkey, et al, 2006). The laboratory bench-scale SAG mill reproduces operating conditions of a commercial SAG mill, in a closed circuit dry grinding environment. The ground product for the laboratory SAG mill is then submitted to the Bond ball mill work index test.

The experiment results confirm that the introduced method is a rapid and accurate method to determine the Bond rod-mill work index. The Bond rod-mill work indices obtained by this method were compared to those of standard Bond work indices with having different test-sieves.

The Bond rod mill grindability test is a widely used tool to estimate the response of ores to rod milling. However, the mass of ore required to conduct the test, which can typically vary from ...

The Bond ball mill work index test is thought to be additive because of its units of energy; nevertheless, experimental blending results show a non-additive behavior. [18] The SPI(R) value is known not to be an additive parameter, however errors introduced by block kriging are not thought to be significant .

Milling – Rod / Ball Mills including Bond Ball Work / Grindability Index . MARC Manufactures and supplies a wide range of ball and rod mills to suit most metallurgical laboratory applications. Our range extends from small 6L jar-type mills that are manually positioned on rollers to large 30L size mills.

The MacPerson Autogenous Grindability Test determines the MacPherson Correlated Autogenous Work Index*. This can be used in conjunction with the Bond Rod and Ball Mill Work Indices to determine power requirements, and to suggest circuit configurations for autogenous grinding (AG) and semi-autogenous grinding (SAG) circuits.

This Grindability Test or Bond Ball Mill Work Index Procedure is used to determine the Bond Work Index of minus six mesh or finer feed ore samples. These equation application methods are used to process <1/2″ ore samples in a Ball Mill using a standard ball charge. Below describes in general terms the Bond Work Index Procedure used by a Professional Metallurgical Testing Laboratory.

The standard Bond Rod Mill Work Index test procedure is firstly to stage crush the feed to pass 12.7 mm, and size a representative sample. The test then involves a series of batch grinds in a standard Bond rod mill. A Bond rod mill is 0.305m by 0.610m, with wave liners (of a form described by Bond), which runs at 40rpm and tilts as described below.

Bond Work Index Tests - Grinding Solutions Ltd. 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 -125mm material Closing screen sizes typically range from 475mm to 212µm

Bond Rod Mill Grindability Test. The test determines the Bond Rod Mill Work Index which is used with Bond's Third Theory of Comminution to calculate net power requirements when sizing ball mills*. Various correction factors may have to be applied. The test is a closed-circuit dry grindability test performed in a standard rod mill.

Bond Work Index Tests. Grinding Solutions offers a range of Bond Work Index Testing from crushability and abrasion to ball and rod mills. For more information on the tests please see below: Bond Low Energy Impact Test. The Bond Low-Energy Impact test can be used to determine the Crusher Work index (CWi), also known as the Impact Work Index.

This test determines the Bond Rod Mill Work Index, which can be used with Bond's Third Theory of Comminution to calculate net power requirements of sizing rod mills. The test is a closed-circuit, dry grindability test, is run in a standard rod mill, and can be performed at …

The Bond rod mill grindability test is a widely used tool to estimate the response of ores to rod milling. However, the mass of ore required to conduct the test, which can typically vary from about 8 to as much as 20 kg, may represent a challenge when sample availability is critical.The present work proposes an alternative procedure, which is based on the size-mass balance model with a ...

work index covering grinding of fine particles is labelled M ib (Morrell, 2008). M ia values are provided as a standard output from a SMC Test® (Morrell, 2004a) whilst M ib values can be determined using the data generated by a conventional Bond ball mill work index test (M ib is NOT the Bond ball work index). M ic and M ih values are also ...
