An alternative mill ball charge is proposed that closely approximates Bond's original total ball mass, number of balls and ball surface area Results of 30 Bond Work index tests of six pure materials (calcite, magnesite, labradorite (feldspar), quartz, andalusite and glass) using closing screen apertures (P 1) values of 500, 250, 125, 90 and 63The 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 310), a question arises as to whether this practice will alter the ball mill work index (BW i) of the materialBond Work Index an overview | ScienceDirect TopicsThe Bond Index conforming rod charge consists of: 6 rods of 125“ diameter and 21“ length 2 rods of 175“ diameter and 21“ length The grinding jar for the Bond Index Rod Mill is 12″ x 24″ in size and has a waveshaped design At least 15 to 20 kg sample material is required to simulate a closed grinding circuit in a ball or rod millBond Index Ball Mill / Rod Mill BT 100 XL RETSCH

## Bond Work Index Determination With A Sepor Batch Ball Mill

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 requiredJK Bond Ball Mill Test Since its introduction in the 1960s, the Bond Ball Mill Work Index (BBMWi) parameter has been extensively used in predicting ball mill power draw Use of Work Index Along with comminution circuit design the work index parameter is widely used in tracking mill performance Due to the age and lack of controls for the test,JK Bond Ball Mill TestThe Bond's standard ball mill is used to determine the work index value of differ ent samples The Bond work index is defined as the kilowatthours per short ton required to break from infinite size to a product size of 80% passing 100 µm If the breakageCORRELATION BETWEEN BOND WORK INDEX AND
