Volume based closed-cycle Hardgrove grindability method

scribe the grindability test introduced by Bond and Max-son in 1943 (Bond and Maxson, 1943), as a compli-cated and time-consuming method, where the time requirement could be as long as 20 hours, thus limiting its applicability. Although, they agree on the importance of the Bond-test utilized in the selection and dimension of mills or crushers.

Small-Scale Tests to Characterise Ore Grindibility

The Bond ball mill grindability test is performed according to the original Bond procedure [4]. It requires 10kg of minus 6-mesh (3.35mm) material that is preferably prepared at the testing facility, by stagecrushing the sample to 100% passing 6-mesh, but normally less than 5kg are actually used in the test. The test is closed with a fine

The first sample was from Tisová power plant (CFBC fly ash) and the second one from Počerady power plant (high temperature fly ash). The modified samples were tested for the effect of grinding time on its grindability and granulometry. For testing of samples was used laser diffraction with particle size analyzer and the grindability was determined.

Simulating the Bond rod mill grindability test -

01/01/2012  The Bond rod mill grindability test is a widely used tool to estimate the response of ores to rod milling. However, the mass of ore required to conduct the test, which can typically vary from about 8 to as much as 20 kg, may represent a challenge when sample availability is critical. The present work proposes an alternative procedure, which is based on the size-mass balance model with a specific
