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]

Correlation Between Bond Work Index And The ball mill is a common piece of equipment in grinding circuits modeling the grinding process in a ball mill is a complex task balls and individual parti cles of varying sizes and geometries collide at various angles and magnitudes the process is further complicated by the production of countless offspring particles to simplify the Basic End Mills

The grinding jar of the Bond Index Ball Mill measures 12″ x 12″ and has wellrounded corners Module Rod Mill Minerals precrushed to < 1250 mm and sieved ; Drillcore precrushed to < 1250 mm and sieved ; Half a drillcore precrushed to < 1250 mm and sieved ; The Bond Index conforming rod charge consists of: 6 rods of 125“ diameter and 21“ length; 2 rods of 175“ diameter and 21

The 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 breakage characteristics of a material remain constant over all size ranges, the calcul ated work index would be expected to remain constant since

Bond ball mill work index: Figure 2: Ball mill for determining Bond ball mill work index 1 For the purists, there were two models in existence at the time: the Von Rittinger and Kick models Neither of these gave results that matched the observations of specific energy consumption from tumbling mills 2 FC Bond; The Third Theory Of Comminution, Transactions AIME 1952 Available from www

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 310), a question arises as to whether this practice will alter the ball mill work index (BW i) of the material

Bond’s work index which is defined as the resistance of the material to grinding The standard equation used by them for the ball mill work index (Bond work index) is as follows / F 80 80 023 082 /10 445 11 GP W i bg i (4)

The Bond ball mill work index test requires the operator to select an appropriate screen size to "close" the test The procedure states that the closing screen size should be such that the product size of the test is the same as the expected product size of the operating plant If the tests were done at the wrong closing screen size, then a ball mill work index adjustment procedure can be

The Bond work index, Wi, is defined in a Bond ball mill on the samples of standard size − 3327 + 0 mm In practice, it is possible to find materials of nonstandard size that are finer than 3

Table I shows the Bond ball mill work index obtained for the ore samples as well as the iron and silica content in concentrate and tail after LIMS The concentrate weight recovery was in the order of 50–60% Furthermore it may be observed that the Bond ball mill work indices for the ore (Wi) varies from 146 to 209 kWh/t The relationship between the ore hardness and iron content presented
