The results show that the aspect ratio of the wollastonite ultrafine powder manufactured by impact smashing method is 10.86:1,and the key of increasing the aspect ratio is to raise the probability of selective smashing in smashing zone.展开更多
文摘The process of preparing wollastonite ultrafine powder by impact smashing method is investigated in order that the product’s size can reach to micrometre grade and aspect ratio over 10∶1,and hence satisfy the application demand as fibre filler in industry. The results show that the aspect ratio of the wollastonite ultrafine powder manufactured by impact smashing method is 10.86:1,and the key of increasing the aspect ratio is to raise the probability of selective smashing in smashing zone.
