Simulation of bond grindability test by using cumulative based kinetic model

Bond Grindability Tests are used to provide basic data for designing indust rial comminution circuits. The Bond Work Index (W-i) of an ore is determine d by Bond Grindability Tests that indicate resistance the to comminution. T he work index is very important but its determination is time consuming and requires skilled staff and 10 kgs of specially prepared feed sample. Conse quently attempts have been made to correlate Bond Tests to classical batch grinding tests. In this study computer simulation of the Bond Grindability Test was made by using a Cumulative Based Kinetic Model. Standard Bond Grin dability Test procedure was carried out to determine the actual work indice s of six samples. Batch grinding tests were also performed to determine mod el parameters. After validation of the model, computer simulations were car ried out and the results were compared. (C) 2000 Elsevier Science Ltd. All rights reserved.
