Technical
Note Investigation of breakage
behaviour of two different pumice stones
In this study, the grindability properties of two different pumice stones,
originated from the Karakaya and the Gelincik areas (Isparta, Turkey), are
investigated at batch grinding conditions based on a kinetic model. For this
purpose, experiments were carried out with eight different mono-size between
1.7mm and 0.106mm formed by a
Ö2
sieve series fraction. Then, parameters of Si and Bi,j equations were
determined from the size distributions at different grinding times, and the
model parameters were compared for two different pumice stones. It was found
out that, the Karakaya pumice is easier to grind than the Gelincik pumice,
taking into account the quite different values of the model parameters. |
