Abstract

The aim of this study is to characterize the shape of comminuted mineral particles quantitatively and to determine the effects of ore characteristics and particle size on particle shape. Particle shape is characterized as roundness, roughness and aspect ratio definitions by using image analysis technique. The quantitative characterization of particles is achieved by using Leco 2001 automatic image analyzer. Jaw crusher is used as comminution machine and five types of chromite ores bedded differently (Bantlı, Dereboyu, Kef, Lasir and Yunuskuyu) were used in the studies. The results are given as a function of particle size. It was found that particle shape of ores comminuted in same device was dependent on type of ore and particle size. Futhermore, general trend graphics for each particle shape parameter in jaw crusher were obtained.

Özet

Bu çalısmanın amacı, ufalanmıs minerallerin tane seklini kantitatif olarak karakterize etmek ve tane sekli üzerine cevher olusum tipi ve tane boyutunun etkisini arastırmaktır. Bu amaç doğrultusunda, görüntü analiz tekniği kullanılarak tane sekli yuvarlaklık, pürüzlülük ve uzunluk oranı tanımlarıyla karakterize edilmistir. Tanelerin kantitatif karakterizasyonu Leco 2001 Otomatik görüntü analizörü kullanılarak gerçeklestirilmistir. Ufalama aleti olarak çeneli kırcı, cevher olarak da farklı olusum gösteren bes kromit cevheri (Bantlı, Dereboyu, Kef, Lasir ve Yunuskuyu) çalısmalarda kullanılmıstır. Sonuçlar tane boyutunun fonksiyonu olarak sunulmustur. Aynı ufalama cihazında kırılan cevherlerin tane seklinin cevherin olusum tipine ve tane boyutuna bağlı olduğu bulunmustur. Ayrıca her tane sekil parametresi için çeneli kırıcıda tüm cevherleri kapsayan genel eğilim grafikleri elde edilmistir.
