Influence of ball milling conditions on particle size distribution of fly ash

Popis výsledku v původním jazyce

The purpose of this study is to determine optimum milling conditions for preparation of nanoparticles with known size distributions and fly ash was chosen as raw material for milling. The effect of milling time, ball size, direction of rotation and stateof milling in dry or wet condition were selected as milling parameters to decide the size reduction of particles.The reduction in particle size of fly ash from micron level to the nano level was carried out using a high-energy planetary ball mill of Fritsch Pulverisette 7, Germany in a sintered corundum bowl of 80 ml capacity using zirconia balls of 10 mm ? and 3 mm ? sizes under both dry and wet conditions for total duration of 5 hours keeping the reverse rotation of bowl OFF and ON. The ball mill wasloaded with ball to powder weight ratio of 10:1. The rotation speed of the planet carrier was 850 rpm. However it was observed in case of dry milling that material starts to stick to the surface of bowl due to role played by surface forc
