Bond Ball Mill Grindability Test Procedure. the bond ball mill work index is a measure of the resistance of the material to grinding in a ball millt can be used to determine the grinding power required for a given throughput of material under ball mill grinding conditionst is a locked cycle test conducted in closed circuit with a laboratory screen.
The Ball Mill Grindability of ores is generally determined by the Bond standard grindability index test method. However, this test and procedure is not applicable to fine materials such as sands; the grindability of fine materials must therefore be determined by a comparative grinding method, for which a reference material of know grindability is required. Suitable reference materials are not

standard grindability test supplies a rela tively accurate method for predicting grinding results. Table I gives the condensed results of 374 standard ballmill grindability tests. Those for each mesh size are arranged in the order of increasing ease of grinding, so that the list for any mesh constitutes an as
BOND ROD MILL GRINDABILITY The Bond rod mill grindability test is performed similarly to the ball mill test. The feed sample is stagecrushed to #189; () and the test is run under a circulating load. The test can also be closed with various sieve sizes, but for AG/SAG mill analyses the standard 14mesh () sieve is typically used.

Here is the old AllisChalmers Bond Work Index Grindability Test Procedure. The standard feed is prepared by stage crushing to all passing a 6 mesh sieve, but finer feed can be used when necessary. It is screen analyzed and packed by shaking in a 1000cc graduated cylinder, and the weight of 700 cc is placed in the mill and ground dry at 250 per cent circulating load. The mill is 12 in. x 12
#0183;#32;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 for grinding, and for ball mill scaleup.
