KONVANSİYONEL İKİ KAMARALI BİLYALI DEĞİRMEN ÖĞÜTME DEVRESİNİN FARKLI ÇİMENTO ÜRETİMLERİNDE İŞLETME PERFORMANSI
Bu çalışmanın amacı, konvansiyonel Polysius® iki kamaralı bilyalı değirmen ve Sepol® dinamik
OPERATIONAL PERFORMANCE OF A CONVENTIONAL TWO-COMPARTMENT BALL MILL GRINDING CIRCUIT AT DIFFERENT CEMENT PRODUCTIONS
The purpose of the study is to assess the grinding and classification performance of aconventional Polysius® two-compartment ball mill and a Sepol® dynamic air classifier closedcircuit process at Portland CEMI/42.5R and Portland composite CEMII/32.5R cement productiontypes. For this purpose, industrial scale sampling surveys were performed around the circuit.JKSimMet Steady State Mineral Processing Software was used to perform mass balance aroundthe circuits. Size reduction performance of the ball mill was determined for the sampling cases.Classification performance of the dynamic air classifier was evaluated based on the efficiencycurve approach. It was determined that, approximately 12% circuit capacity increase could beachieved in composite cement production when ball mill, ball mill filter and air classifier powerconsumptions were considered. This figure corresponded to overall energy savings of 7% in ballmill grinding.
