The solid fossil fuel prepared at mono size groups were ground as dry in stirred mill which was run 360 rpm
stirring speed and Bond ball mill which was run 70 rpm. In stirred mill, breakage rate reached maximum
when the he ratio of “Grinding medium size/Maximum size of the material ground” was approximately
2.5. The sample charged in the mills occupies as much as 90% of the gap volume between the balls in
the mills. The parameters “aT”, an important parameter depending on mill specifications, were found as
1.08 and 0.53 in stirred mill and ball mill respectively. This situation is the result of the specific rate of
breakage at mono size groups, -212+150 µm and -425+300 µm, were carried out faster at stirred mill
approximately 7 and 5.5 fold more than that at ball mill. Although specific rate of breakage reached its
maximum at 425 µm in stirred mill, it was determined as 2360 µm in ball mill.

Dar tane boyut gruplarında hazırlanmış fosil yakıt, karıştırmalı değirmende 360 dev/dak ve Bond
değirmeninde 70 dev/dak ile kuru olarak öğütülmüştür. Karıştırmalı değirmende “Bilya çapı/Değirmene
beslenen maksimum tane boyutu” arasında yaklaşık 2,5 gibi oransal yaklaşım olduğunda, kırılma hızı
maksimum gerçekleşmiştir. Değirmenlerde, bilyalar arası boşluğun %90’ı malzeme ile doldurulmuştur.
Değirmene bağlı kırılma parametre değeri, “aT”, karıştırmalı değirmende 1,08 ve bilyalı değirmende
0,53’dür. Bu, -212+150 µm ve -425+300 µm dar tane boyut gruplarında karıştırmalı değirmen lehine,
yaklaşık 7 ve 5,5 kat hızlı gerçekleşen kırılma davranışının sonucudur. Karıştırmalı değirmende özgül
kırılma hızı 425 µm tane boyutunda maksimum iken, bilyalı değirmende bu boyut 2360 µm’dir.
