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.
Similar to a Comparative Work Index, this test is an open circuit dry batch grindability test run in the standard Bond Ball Mill for a set time. It can be used at mesh sizes from 65 to 200 mesh (normally 100 mesh). The test requires calibration against the standard Bond Ball Mill Work Index test to estimate the Work Index.

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 test much achieve a .
Correction of Bond Ball Mill Work Index Test for Closing Mesh Sizes It is commonly known that one must run the Bond ball mill work index test such you pick .
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 ...
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.
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 ability to simulate the Bond work index test also allows examination of truncated ball mill feed size distributions on the work index. For grinding circuits where the feed to a ball mill is sent directly to the classifier and the cyclone underflow feeds the ball mill (see Figure 3.10), a question arises as to whether this practice will alter the ball mill work index (BW i) of the material ...
Coal Mill. Coal mill is a kind of ball mill, which is often used to crush and grind coal bricks into powder, so it is also called coal grinding mill. Coal mill is the main equipment in cement plant, which is used for drying and grinding of coal.

A Bond Ball Mill Work Index test is a standard test for determining the ball mill work index of a sample of ore It was developed by Fred Bond in 1952 and modified in 1961 (JKMRC CO, 2006) This index is widely used in the mineral industry for comparing the resistance of different materials to ball milling, for estimating the energy required.
Safety is a prime consideration for all Alsto equipment and the Bond Index Ball Mill is supplied equipped with acoustic enclosure. The ball mill is designed to accept a ball charge in accordance with F. C Bond's standard. This ball charge consists of 286 balls as follows: 44 x 35mm balls; 67 x 30mm balls; 10 x 25.4mm balls, 71 x 19.05mm balls and
This study aims to develop a new approach toward estimating the Bond ball mill work index (BBWI) by applying a series of kinetic grinding tests with Bond standard mill. ... The Bond work index, Wi ...
