Stirred Mills – Ultrafine Grinding - ScienceDirect

2016-1-1 · Figure 10.1 shows the difference in energy efficiency between a laboratory ball mill and a stirred mill grinding a gold ore using 6 mm diameter alumina balls as media. At a fine grind size there is a clear advantage in energy consumption for a stirred mill over the tumbling mill. However, as the grind size coarsens, the difference in specific energy required to achieve the grind lessens.

2011-3-10 · An antimonial refractory gold/silver ore sample obtained from Akoluk (Ordu-Turkey) was used in this work. The ore sample was crushed down to − 4 mm using jaw and rolls crushers, and riffled to obtain 1 kg representative sub-samples.These were then ground in laboratory rod mill at 50% pulp density for 40 min (80% passing size, d 80 = 60 μm) prior to ultrafine grinding using the stirred mill.

Comparative comminution efficiencies of rotary, stirred ...

2021-7-15 · Mucsi & Racz (2017) also demonstrated that a stirred-bead mill resembling our SBM, which they called a ‘high energy density mill,’ was highly efficient for the ultrafine dry comminution (10 μm range) of grapeseed, which is a tenacious and multi-layered lignocellulosic material. On the other hand, a VBM-type mill uses less electric power to ...
