TRİBOELEKTROSTATİK AYIRMA İLE İNCE BOYDA KÖMÜR ZENGİNLEŞTİRİLMESİNİN İNCELENMESİ

Öz Bu çalışma kapsamında bir triboelektrik ayrım düzeneği tasarımı ve bu düzeneğin ülkemizdeki belli başlı kömür cevherlerinin ince boyda zenginleştirilmesinde kullanımı incelenmiştir. Deneysel çalışmalarda kullanılmak üzere Tunçbilek ve Soma bölgelerinde konumlanmış, işletmesi devam eden dört farklı lavvardan kömür numuneleri temin edilmiştir. Deneysel çalışmalarda kullanılmak üzere Hacettepe Üniversitesi Maden Mühendisliği Bölümü’nde geliştirilen triboelektrostatik ayrım düzeneği 35 kV’a kadar statik yük üretebilmektedir. Gerekli statik yükün sürtünme ile sağlanmasına ilişkin öncül testleri takiben kömür numuneleri ile zenginleştirme işlemleri gerçekleştirilmiştir. İki ayrı bölgeden temin edilen dört farklı kömür numunesi ile gerçekleştirilen deneysel çalışmalar sonucunda, triboelektrostatik ayrım ile kömürün yapısına bağlı olarak ince tane boylarında %50’leri aşan kül uzaklaştırma verimleri elde edilebildiği görülmüştür.
