2013-09-01 · Ball milling is a top down approach and a method to reduce size of particle while Zeolite is a valuable inorganic materials having wide variety of applications. In this paper, ball milling of commercial synthetic Zeolite powder was studied with their time varied. Wet ball milling was selected as a potential means to decrease the particle size of Zeolite over dry grinding.

The present work covers the effects of milling time on the characteristics such as crystal phases, particle sizes, morphology and physiology of the powder. The produced nanoparticle powders were characterized by SEM-EDX, XRD, and XRF. The milling time was carried out at (t=0, 20, 40, and 60 minutes) at a constant milling speed of 940 rpm.

Get price23.12.2013 · From the result the size reduction increases as we increase the number of rotations of the ball milling. Meanwhile, increase in the time taken for ball milling will also increase the size reduction. From the graphs, we can see that as the size reduction increases, the particle sizes obtained will form a less steep curve in the graph.
