1. Introduction. Stirred milling technology has been firmly established in the last 20 years as superior to ball mills for fine and regrinding operations due to its superior energy efficiency (Jankovic, 2000).Stirred mills are now commonly used in many sectors of the mining industry, though they have been used in other industries for many years …
Milling devices used: (a) knife mill, (b) impact mill (IM), (c) rotary ball mill (RBM), (d) stirred ball mill (SBM), and (e) vibratory ball mill (VBM). Before final comminution in the different ball mills, all samples were re-dried to a moisture content of about 3%, as measured by weight loss after oven-drying for 2 h at 135 °C.
The present literature review explores the energy-efficient ultrafine grinding of particles using stirred mills. The review provides an overview of the different techniques for size reduction and the impact of energy requirements on the choice of stirred mills. It also discusses the factors, including the design, operating parameters, and feed material …
