PİRİNA YAĞININ ÖĞÜTME YARDIMCISI OLARAK KULLANABİLİRLİĞİNİN ARAŞTIRILMASI

Bu çalışmada, kalsitin kuru mikronize boyutlara karıştırmalı bilyalı değirmende öğütülmesinde pirina yağının öğütme yardımcısı olarak kullanılabilirliği araştırılmıştır. Bu amaçla doğrultusunda ilk aşamada farklı stres yoğunlukları oluşturularak optimum öğütme koşulları belirlenmiştir. İkinci aşamada ise pirina yağının kullanılabilirliği araştırılmış ve saf bir öğütme yardımcısı olan trietanolamin ile karşılaştırılmıştır. Deneysel sonuçlar öğütme yardımcısı miktarı, enerji tüketime ve tane boyutu göz önünde bulundurularak değerlendirilmiştir. Elde edilen sonuçlara göre optimum stres yoğunluğu aralığı 500 kJ/kg ve 1000 kJ/kg enerji seviyelerinde yaklaşık 1-2*10-3 Nm olarak belirlenmiştir. 2000 kJ/kg enerji seviyesinde TEA ve pirina yağı kullanımı ile 4 µm ve altı tane boyutuna sahip ürünler üretilebilmiştir. Pirina yağı kullanımı ile özellikle ileri enerji seviyelerinde (1000 kJ/kg ve 2000 kJ/kg) TEA’ya yakın tane boyutları elde edilmiştir.

Anahtar Kelimeler:

pirina yağı, öğütme yardımcısı, karıştırmalı bilyalı değirmen, kalsit
