bond ball mill work index determination

The grinding jar for the Bond Index Rod Mill is 12″ x 24″ in size and has a wave-shaped design. 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 ...

Determination Of The Bond Work Index Using An Ordinary

The work index of a particular material is determined in the laboratory by conducting the standard Bond grindability test. Bond developed separate tests for the rod mill and the ball mill. The simplified test method described in this paper, which is used at Anaconda Research Center to approximate the work index, is an alternative procedure to .contact us...

PDF Determination of the Bond work index on samples of

The Bond work index, W i , is defined in a Bond ball mill on the samples of standard size −3.327 + 0 mm. 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

Operating work index is not the specific energy consumption

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 a milling .Fote, a leading manufacturer of ball-mill machinery...

Technical Information SMC Testing

However, if the sample is to be prepared by cutting with a diamond saw (cut-core method) as little as 5kg is normally sufficient. Also remember that the products from the SMC Test can be re-used for Bond ball work index testing, the SMC Test being effectively used as a feed preparation step for the Bond ball work index test.

Kinetic grinding test approach to estimate the ball mill

Kinetic grinding test approach to estimate the ball mill work index 343 The W i parameter is obtained from Bond’s ball mill grindability test (Bond, 1961). This test is performed according to the standard Bond procedure which proposed model is presented in Eq. 1. …

Procedure for determination of ball Bond work index in the

Starting from the first-order grinding kinetics defined by means of the Bond ball mill, this paper discusses a simplified procedure for a rapid determination of the work index by just two grinding tests. The applicability of the simplified procedure has been proved on …

Bond Work Index an overview ScienceDirect Topics

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 ….chad professional gold iron production plant Fote Mining Machinery Co
