Abstract

The ultrafine grinding of talc with various additives was carried out using attrition ball mill with a laboratory scale. The additives used in dry and wet base ultrafine grinding processes were methyl alcohol, sodium diphosphate, ethylene glycol, triethanol amine, benzoic acid and calcium stearate. All of experiments were carried out by batch operation. The variations of median size of products with grinding time were measured by particle size analyzer. The energy consumption was calculated by using torque meter. The results showed that all of additives except for methyl alcohol were satisfactorily effective for the ultrafine grinding of talc. The energy consumption was reduced from 30% to 70%.

분쇄공정에서 분쇄효율의 향상 및 분쇄에너지의 저감을 위한 수단으로 분쇄조제의 사용은 매우 유용하고 경제적인 방법으로 대두되고 있는데, 본 연구에서는 활석 분쇄공정에서 다양한 종류의 분쇄조제에 대한 분쇄효율 및 분쇄에너지의 변화를 고찰하여 최적의 분쇄조제 및 첨가량 등을 도출하고자 하였다. 분쇄조제로 메틸알콜, 인산나트륨, 에틸렌글리콜, 트리에탄올아민, 벤조산, 칼슘스테아레이트 등을 사용하였는데, 메틸알콜을 제외한 모든 분쇄조제를 사용할 경우 현저히 분쇄효과가 향상되었으며, 분쇄에너지로 30～70%까지 저감이 가능함을 확인할 수 있었다. 이러한 결과는 실제 비금속광물 분체 제조 공정에 적용이 가능할 것으로 기대된다.
