Effect of Bimodal and Monosized Grinding Media on Dry Grinding of Barite

Abstract

This study investigates the effects of the design of high-density zircon (ZrO2) grinding media (1-3 mm) on dry grinding of barite (BaSO4, d50= 2.83 µm) in a vertical stirred media mill. Grinding experiments were carried out by using different proportions of finer grinding media (20 wt.%, 40 wt.% and 80 wt.%) and different size ratio of finer-coarser media (0.5 and 0.67). Besides, the surface areas (Sbw, m2/kg) of grinding media on grinding performance were investigated. If the best two experimental results are compared, it is found that the Sbw of the bimodal and monosized media are very close together. The experimental results were evaluated based on the product particle size (d50, d90), and the geometric standard deviation of barite particles (d84/d16). The findings showed that the finer grinding media alone was not very effective.

Baritin Kuru Öğütülmesinde Karışık ve Tek Tip Öğütücü Ortamın Etkisi

Abstract

Bu çalışma dikey karıştırmalı bilyalı değirmende baritin (BaSO4, d50= 2,83 µm) kuru öğütülmesinde yüksek yoğunluğa sahip zirkon (ZrO2) (1-3 mm) öğütme ortamı tasarımının etkisini araştırmaktadır. Farklı miktarda ince bilya (%20, %40 ve %80) ve farklı ince-iri bilya oranları (0,5 ve 0,67) kullanılarak mikron-altı öğütme gerçekleştirilmiştir. Ayrıca, öğütücü ortamın yüzey alanlarının (Sbw, m2/kg) öğütme performansına etkisi araştırılmıştır. En iyi deney sonuçları karşılaştırıldığında, karışık bilya boyut dağılımının yüzey alanı ile tek tip bilya boyut dağılımının yüzey alanı birbirine çok yakındır. Deneysel sonuçlar ürün boyutu (d50, d90) ve barit tanelerinin geometrik standart sapması (d84/d16) dikkate alınarak değerlendirilmiştir. Sonuçlar, tek başına ince boyutlu öğütücü ortamın çok fazla etkili olmadığını gösteriyor.
