Table of Bond Work Index by Minerals - 911 Metallurgist Sep 22, 2017 ... This Table of Ball Mill Bond Work Index of Minerals is a summary as tested on ''around the world sample''.

Such standardized measurements can produce two quantities: abrasion rate and normalized abrasion rate (also called abrasion resistance index). The former is the amount of mass lost per 1000 cycles of abrasion. The latter is the ratio of former with the known abrasion rate for some specific reference material.

* Bond F. C., "Crushing Tests by Pressure and Impact", Trans AIME, Vol 169, 1947, pp 58-66. 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 Bond Abrasion Test determines the Abrasion Index, which is used to determine steel media and liner wear in crushers, rod mills, and ball mills. Bond developed the following correlations based on the wear rate in pounds of metal wear/kWh of energy used in the comminution process.

In practice, it is possible to find materials of non-standard size that are finer than 3.327 mm.In this work, a procedure for the calculation of the Bond work index is suggested for cases when the ...

3.5.1. Effect of the test screen size on work index. The Bond work index is not solely a material constant but is influenced by the grinding conditions. For example, the finer the grind size desired, the higher is the kWh/t required to grind to that size. Magdalinovic measured the Bond work index of three ore types using different test screen ...

granite, feldspar and quartz were tested for hardness, abrasion, compressive strength and modulus of elasticity and the bond work index of these samples were estimated. The value of Bond work index of the above samples has shown a variation from 10.8 kwh ton-1 for bauxite (high abrasion value and low compressive strength) to 20.4 kwh ton- 1

The Bond rod mill work index (Wi RM, or RWi) conducted from a feed size of approximately 10 mm to a product size on the order of 1 mm. The Bond crushing (impact) work index (Wi C, CWi, LEIT or IWi) conducted on specimens of a nominal dimension between 50 mm and 75 mm. The product size is not relevant to this test; it is a determination of the ...

Bond's law is typically used for intermediate particle sizes[Sad15]. The bond work index of granite is expected to be the highest due to the ore being mostly composed of the hard mineral quartz. Bond Work index values of granite presented in literature range from around 14-15. Limestone is theorized to have a Bond Work index with a value of ...

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.

The Bond low-energy impact test apparatus consists of two pendulum hammers mounted on two bicycle wheels, so as to strike equal blows simultaneously on opposite sides of each rock specimen. The height of the pendulum is raised until the energy is sufficient to break the specimen (Bond, 1947), and then the crusher work index (CWI) or impact work ...

Mar 29, 2017· The abrasion test is mainly used to assess hammer wear in an impact type crusher (e.g. a hammer mill), hence the much higher rotational speed, whereas the Bond abrasion .

At least 15 to 20 kg sample material is required to simulate a closed grinding circuit in a ball or rod mill. The Rod Mill Work Index (RWI) is used for particle size determination in a size range from 25 mm down to 2.1 mm whereas Ball Mill Work Index (BWI) is used for the range from 2.1 mm down to 100 µm. Adjustment of grinding parameters:

Overview. The Los Angeles (L.A.) abrasion test (Figure 1) is a common test method used to indicate aggregate toughness and abrasion characteristics. Aggregate abrasion characteristics are important because the constituent aggregate in HMA must resist crushing, degradation and disintegration in order to produce a high quality HMA.. Figure 1: L.A. abrasion testing equipment.

Moreover, using different explosives brought about sensible changes in results, so that substituting ANFO with pentolite or emulite decreased the Bond index by 9.2% and 6.7% respectively, and ...
