Introduction Bond’s work index model of quantifying mineral grindability was born out of the desire for a beter way of scaling up laboratory grindability test results to industrial-scale grinding mills (Lynch & Rowland, 2005). The Allis-Chalmers company (now Metso) collected a great deal of operating and laboratory data during the 1930s and 1940s with the original …

200581 · Abstract Friability of rocks and ores can be determined by brittleness tests. A test apparatus to determine friability value has been designed to suit limestone strength characteristics used in cement production. The friability values of barite, marble, limestone and bauxite have been determined and compared with the corresponding Bond work …

20161210 · A systematic investigation was carried out to predict Bond's work index using simple field measurable properties of rocks. Tests were conducted on Basalt, Slate and Granite using a laboratory scale ball mill and rock properties namely density, Protodyakonov's strength index and rebound hardness number were determined.

20211028 · Then, the relations between Bond work index (BWi), as one of the most important geometallurgical variables and the primary grindability index, and rock geomechanical properties are investigated based on the previously published studies. The BWi is the main parameter for measuring the resistance to the grinding of ore minerals.

20131224 · In recent, the brittleness test/friability value of bauxite, limestone, barite, marble, copper ore, andesite and ulexite [6-9] is also suggested to find out the work index of material. The Bond’s grindability test can be used to determine the work index of any type of ore or material. But the process is tedious and long time consumption.

The Abrasion Index is a recognised procedure to quantify abrasiveness and approximate wear that can be expected on media and mill liners. The test requires a minimum of 5kg +25mm material. GSL 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:
