Typical F 80 size Typical P 80 size 2500 #181;m 75300 #181;m Models: Bond models, SGI, Morrell Mi 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.
Insmart Bonds BallMill Work Index is a measure of the resistance of the material to grinding in a ball mill. This Index is widely used in the industry for comparing the resistance of different materials to ball milling, for estimating the energy required for grinding and for ball mill scaleup.
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 LowEnergy Impact test can be used to determine the Crusher Work index (CWi), also known as the Impact Work Index.

MAGDALINOVIC University of Belgrade, Technical Faculty at Bor, 19210 Bor (Yugoslavia) (Received November 24, 1987; accepted after revision November 17, 1988) ABSTRACT
However, the ball diameters vary due to wear. Therefore, the total ball number should be adjusted from time to time to ensure a total mass of grams. The grinding jar of the Bond Index Ball Mill measures 12 x 12 and has wellrounded corners. Module Rod Mill. Minerals precrushed to lt; mm and sieved ; Drillcore precrushed to
the work index depending on the grind size. In this way, work index values are usually obtained for some specific grind size that characterizes the grinding operation to design or under evaluation. This study was carried out in a standard bond ball mill 305 mm x 305 mm size in mineral processing laboratory, in the mining engineering department
The Bond ball work index is widely used in the field of minerals processing as an indicator of ore grindability. The work index is determined by means of a lockedcycle test procedure that typically requires seven to eight cycles to stabilise at a recirculating load of 250%. A typical test requires
This Table of Ball Mill Bond Work Index of Minerals is a summary as tested on around the world sample. You can find the SG of each mineral samples on the other table.
The test work program was carried out on those five ore samples obtained from the copperporphyry orebodies. Total of 38 Bond work index tests, including duplicates, were done. Standard Bond ball mill test procedure were carried out on crushed ( mm / 6 mesh) material at different

This study was carried out in a standard bond ball mill 305 mm x 305 mm size in mineral processing laboratory, in the mining engineering department
grinding conditions. Typical feed load and mill speed in practice were used in order to make the grinding environment as close as possible to that in large scale grinding. The Bonds work index of Baban Tsauni (Nigeria) ore was found to be /tonne. Keywords: Grindability, comminution, energy, mineral, comparative . Introduction
Ball mill design requires a Bond work index, BWi, for ball mills at the correct passing size; SAG mill design requires an appropriate SAG test, for example, SPI (Chapter 5). Flotation design needs a valid measure of kinetics for each sample, including the maximum attainable recovery and rate constants for each mineral ( Chapter 12 ).
Bond Work Index Tables (Wi) Free download as PDF File (.pdf), Text File (.txt) or view presentation slides online. Here there are given tables from various sources for the Bond work index values of mining materials (ores, industrial minerals and rocks). These work indexes can be used for the determination of tumbling mills (rod, ball mills) power.
The Bond work index (W i ) is widely used in the mineral industry for comparing the resistance of different ores to ball milling and can be used to estimate the energy required for grinding, which
The Bond ball mill work index test is thought to be additive because of its units of energy; nevertheless, experimental blending results show a nonadditive behavior. [18] The SPI(R) value is known not to be an additive parameter, however errors introduced by block kriging are not thought to be significant .
Bond Ball Mill Work Index is used for determine the grindability of materials, and help to choose the suitable grinding equip. Position Home Page gt;gt;gt; Products gt;gt;gt; Laboratory Equipments gt;gt;gt; Lab Grinder. Bond Ball Mill Work Index.
