Abstract

Stirred media mills are widely used for ultra fine grinding of minerals and other materials to particles size below a few micrometers in different industrial fields such as ore dressing, plastic, ceramics, paint, food and cosmetic. These mills can be classified into a number of different subcategories predominantly defined by the speed, geometry, and orientation of the media agitator or stirrer. Two basic types of stirred mills are available, the vertical stirred mill and the horizontal stirred mill. The specific energy consumption for grinding is less than that of tumbling mills due to the high media volumetric loading in stirred mills. In stirred mills, mineral type, and specific energy input, the bead size and load volume play an important role in the comminution process and influence the stress intensity and stress number taking place in mill. In this paper, the parameters effecting grinding and general properties of stirred mills are discussed and applications in ore dressing as well as other industrial fields are reviewed.

Özet

Karıştırmalı ortam değirmenleri minerallerin ve diğer malzemelerin birkaç mikron altı tane boyutuna çok ince öğütülmeleri için cevher hazırlama, plastik, seramik, boya, gıda ve kozmetik gibi farklı endüstri kollarında yaygın bir şekilde kullanılmaktadır. Bu değirmenler hız, geometri ve ortam karıştırma ya da karıştırıcı şekliyle tanımlanan farklı türlerde sınıflandırılırlar. Karıştırmalı değirmenlerin düşey ve yatay değirmenler olmak üzere iki temel tipi vardır. Karıştırmalı değirmenlerde öğütme için harcanan spesifik enerji yüksek şarj hacminden dolayı geleneksel değirmenlerde harcanan enerjiden daha azdır. Öğütme işleminde mineralin türü, spesifik enerji girdisi, ortam boyutu ve şarj oranı önemli rol oynamakta ve değirmen içinde oluşan stres şiddeti ve sayısını etkilemektedir. Bu çalışmada, karıştırmalı değirmenlerin genel özellikleri ve öğütmeyi etkileyen parametreler tartışılarak cevher hazırlama ve diğer endüstrideki uygulamaları değerlendirilmiştir.
