Abstract

This study is aimed at describing in detail the working principle of a Cyclojet cell developed by the Department of Mining Engineering of Zonguldak Karaelmas University, Turkey, and testing it to nd out whether it can be used in cleaning bituminous coal slimes. 80% of the bituminous coal slime used in the tests was ner than 53 m and it had an ash content of approximately 49%. By using the Cyclojet, the coal slimes yielded clean coal products having 11,32% ash content with 72,80% combustible matter recovery. Tests conducted in the Jameson cell with the same coal slimes produced clean coals having an ash content of 14,40% with 73,82% combustible matter recovery. A release test was also applied to the coal slimes in a mechanical cell in order to assess the otation performance of the Cyclojet cell and compare it with that of Jameson cell. In conclusion, it has been established that the Cyclojet cell produces cleaner products than the Jameson cell with approximately the same otation yields. The underlying reason is the cyclonic jet action (by centrifugal forces) occurring in the Cyclojet cell and a vortex ow on the cell surface

Abstract

Bu çalışmada, Zonguldak Karaelmas Üniversitesi, Maden Mühendisliği Bölümünde geliştirilmiş olan
Siklojet hücresinin çalışma ilkeleri ayrıntılı olarak anlatılmış ve bitümlü kömür şlamlarının temizlenmesi
için denenmiştir. Deneylerde kullanılan bitümlü şlam kömürün %80’i 53 mikronun altında olup kül içeriği
yaklaşık %49’dur. Söz konusu şlam kömürlerden Siklojet hücresi ile %11,32 küllü temiz kömür %72,80
yanabilir madde verimi ile kazanılmıştır. Aynı kömürlerle Jameson hücresinde yapılan çalışmalar
sonucunda %14,40 küllü temiz kömür, %73,82 yanabilir madde verimi ile kazanılmıştır. Ayrıca, Siklojet
hücresinin flotasyon performansının değerlendirilebilmesi ve Jameson hücresi ile karşılaştırılabilmesi
için mekanik hücrede kömür şlamlarına “release test” uygulanmıştır. Sonuçta, Siklojet hücresinin
Jameson hücresine göre daha temiz ürünler verdiği ve flotasyon veriminin ise yaklaşık olarak aynı
olduğu saptanmıştır. Bunun arkasında yatan temel neden, Siklojet hücresindeki siklonik jet hareketi
(santrifüj kuvvetleri ile) ve hücre yüzeyinde meydana gelen girdap akımıdır
