Size Reduction | International Fine Particle Research Institute

Since the formation of IFPRI in 1979, its membership has been interested in the millennia-old process of size reduction, as it is the most energy intensive and inefficient particulate solids process and is also complex and the least understood. From the process engineering view point, the interest is in the energy utilisation.

Variables affecting the fine grinding of minerals . - 911 Metallurgist

milling technology has occurred relatively quickly. The first stirred mills were introduced in 1953 (Shibayama and Mori, 1999) and the driving force behind their in- troduction was the increasing need for the fine particles processing, i.e. grinding. Since their initial introduction, more than 400 Tower and Verti mills have been.
