Bond Work Index Test Ball Mill US$ 13,800 The FC Bond Work Index Test Ball Mill was designed by F. C. Bond for use in determining the Bond Index, a measure of grindability and power required for grinding applications. The FC Bond Mills are used in laboratories throughout the world.
Dec 04, 2020 Work index can change as a function of the product size of a Bond ball mill grindability test, which is controlled by the closing mesh size the test operator has chosen for the test.
Jan 01, 2013 To calculate the Bond work index (W i) in a standard laboratory scale rod-mill, Bond derived the following equation: (1) W i = 62 P i 0.23 G i 0.625 10 P-10 F kw h sh t where F is 80% passing size of original feed, P is 80% passing size of circuit product and P i is the test-sieve size in μm .
The Bond rod mill work index is not as common as the Bond ball mill work index, and there are two different variations on the mill apparatus.The SAGMILLING.COM models expect a mill with a wave liner , and is not compatible with mills using smooth liners .
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 Ball Mill Work Index, BWi, kWh/t 13.4 Bond Rod Mill Work Index, RWi, kWh/t 18.1 Table 1. Example of AG/SAG Ball Mill Circuit Wio Calculations [1] [2] ABstrAct Optimum use of power in grinding, both in terms of grinding efficiency and use of installed capital, can have a large effect on profitability.
Oct 24, 2018 The work index can either be measured in the laboratory (the Bond ball mill work index determination is a common example) or it can be calculated from the operating performance of …
Jul 30, 2020 A Bond Ball Mill Work Index may also be used in the simulation and optimisation of existing mill(s) and the associated grinding circuit(s). Sample requirements: A minimum of 8 kg of material crushed to nominally minus 10 mm is preferred. JKTech would stage crush the sample to minus 3.35 mm, as required for the Bond Ball Mill Work Index test feed.
The Bond work index is one of the most useful and interesting parameters used in designing grinding equipment. However, it must be obtained under restrained conditions, especially in regards to the Bond standard lab mill. The main objective of this study is to show how this index can be obtained using a Denver ball mill, which is present in most mineral processing laboratories.
Bond 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 212 m. Abrasion Index Test
The Work Index is used when determining the size of the mill and grinding power required to produce the required ore throughput in a ball mill [Bond 1961].
Dec 04, 2020 The laboratory procedure for running a Bond ball mill work index test requires that the operator choose a closing screen sieve size. The instruction is to choose a sieve size that results in the ...

The ball mill work index laboratory test is conducted by grinding an ore sample prepared to 100% passing 3.36 mm (6 mesh) to product size in the range of 45-150 m (325-100 mesh), thus determining the ball mill work index (Wi B or BWi). The work index calculations across a narrow size range are conducted using the appropriate laboratory work index determination for the material size of interest, or by …
Sep 22, 2017 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.

Sep 22, 2017 A “Bond” rod mill work index is to be determined in an apparatus with a wave liner. The author is aware of four laboratories that offer a rod mill work index test where the lining of the mill is either smooth, or smooth with a small number of primitive lifters that do not constitute a wave liner (one of the four laboratories is known to be investigating replacing the liner with a wave).
It is commonly known that one must run the Bond ball mill work index test such you pick a closing mesh to give a P80 close to desired grind size. This is because work index frequently changes as a function of the product size in comminution. If target grind size during a project is changed, or if

Hello; Mobile crushers are track-mounted rock crushing machines that are easily movable on and between production sites. They are widely used in aggregates production, recycling applications, and in mining operations. Mobile crushers can replace stationary crushing systems, which reduces the need for hauling and thus cuts operational costs.
