Abstract

In this study, the effect of grinding aid on dry calcite grinding using vertically and horizontally orientable stirred ball mill was investigated. The results obtained from the vertical and horizontal orientation of the mill were evaluated based upon the particle size (d50 and d90). For vertical orientation, experimental results indicated that the d50 and d90 sizes can be improved by 40% and 60%, respectively by using grinding aid at 2000 g/t when compared to no aid condition. For horizontal orientation, it was understood that improvement in d50 size by 45% size and improvement in d90 size by 62% could be obtained. In addition, agglomeration phenomena were determined by scanning electron microscope (SEM) images of products obtained from the presence (2000 g/t) and absence (0 g/t) of grinding aid.

Özet

Bu çalışmada, kalsitin dik ve yatay konumlandırılabilen karıştırmalı bilyalı değirmende kuru öğütülmesinde öğütme yardımcısının etkisi incelenmiştir. Değirmenin dik ve yatay konumundan elde edilen sonuçlar tane boyutu (d50 ve d90) göz önünde bulundurularak değerlendirilmiştir. Deney sonuçlarından, dik konum için d50 ve d90 boyutları öğütme yardımcısız yapılan deneylerle karşılaştırıldığında 2000 g/ton öğütme yardımcısı kullanılmasıyla d50 boyutunda %40, d90 boyutunda ise %60 oranında bir iyileştirme sağlanabileceği görülmüştür. Yatay konum için ise; d50 boyutunda %45, d90 boyutunda %62 oranında bir iyileştirme yapılabileceği anlaşılmıştır. Ayrıca, öğütme yardımcılı (2000 g/ton) ve öğütme yardımcısı kullanılmadan (0 g/ton) yapılan deneylerden elde edilen ürünlerin taramalı elektron mikroskobu (SEM) görüntüleri çekilerek topaklanma durumları tespit edilmiştir.
