Effect of heat treatment on breakage rate function of ulexite

Ipek H., Sahan H.

Physicochemical Problems of Mineral Processing

Vol. 49, iss. 2

651--658

The kinetics of batch grinding and heat treated of ulexite using different size fractions (–3350+2360, –2360+1700, –1700+1180, 1180+850, –850+600, –600+425, –425+300, –300+212 and – 212+150 micrometers was determined using a standard Bond ball mill. It was found that breakage of ulexite follows the first order behavior for all feed sizes with the correlation coefficients equal to approximately 98%. The dry grinding of the single-sized fraction and heat treatment of ulexite showed that heat treatment samples were ground much faster than the original ulexite samples.

Determination of grindability characteristics of zeolite

In this study grindability of zeolite was studied. The work index of zeolite was determined for three different test sieves. In terms of work indexes, there was insignificant difference between the test sieves. Additionally, the breakage rate and distribution parameters were also determined. The fastest breakage rate was obtained for -1700+1180 µm feed sizes and found breakage distributions functions were non-normalisable.
