Öğütme devrelerinin modellenmesi, devre tasarımı ve optimizasyonu açısından önem taşımaktadır. Doğru ve güvenilir modeller için malzemenin kırılma dağılımı fonksiyonunun tayin edilmesi önem arz etmektedir. Çalışmada, her bir kamara için ayrı kırılma testlerinin kullanıldığı model yapısı üzerine odaklanılmıştır. Çalışma kapsamında, 2 kamaralı bilyalı değirmen içeren çimento öğütme devresi etrafında ve değirmen içinde örnekleme çalışmaları yürütülmüş ve alınan numunelerin tane boyu dağılımları belirlenmiştir. Sonrasında madde denkliği çalışmaları yürütülmüştür. Değirmenin ilk kamarası için tek tane ağırlık düşürme testleri, ikinci kamarası için ise Hardgrove kırma testleri yürütülmüş ve tane boyuna bağlı kırılma dağılım fonksiyonları hesaplanmıştır. Çalışma Hardgrove tekniğinin bilyalı değirmen modelindeki ilk uygulamasıdır. Kamaralar ayrı olarak mükemmel karışım modeli kullanılarak modellenmiştir. Simülasyon sonuçları ürün tahminlerinin 1. kamarada tutarlı olduğu ve 2. kamarada ise Hardgrove testinin tek tane testine göre daha olumlu sonuçlar verdiğini göstermiştir.
Modelling of grinding circuits is crucial for circuit design and optimization. Determination of breakage distribution function of the materials is important for accurate and reliable modelling. In this study, the model structure was focused on using separate breakage tests for each chamber. Within the study, sampling studies were performed around the grinding circuit containing 2-chamber ball mill and inside the mill and, particle size distributions of collected samples were determined. Then mass balance studies were performed. Single particle drop weight test for the chamber-1 while Hardgrove test for the second chamber of the mill was carried out then size-dependent breakage distribution functions were calculated. The study is the first application of using Hardgrove technique in the ball mill model. Each chamber was modelled separately by using Perfect Mixing Model. Simulation results showed that the product estimations were accurate for the chamber-1 that the Hardgrove test was suitable for the chamber-2.
