  Stirred Milling Technology – A New Concept in Fine Grinding

  al., 2005). In stirred mills there are no freefalling possibilities for grinding media, meaning that impact action does not occur. The bead size is small, typically 1 to 6 mm which means a large amount of contacts and high grinding efficiency especially in the finest range, where ball mills are not effective or cannot reach P80 10 to 40 µm.

  Analysis of stirred mill performance using DEM

  · DEM was used to investigate the internal bed dynamics for each mill. Analysis of the performance of each mill was made through consideration of the global flow patterns, power draw, the spatial distribution of energy dissipation and the nature of the collisional environment producing the feed comminution using energy spectra.

  However, if we now look at industrial mills, which could have as much as 8 m in diameter, for instance, we would run out of memory (>10 GB) if we include particles with a minimum size of mm, which are just about the coarsest size present in the mill, if we use the same ball and particle size distributions!

  Towards a Better Understanding of Stirred Milling

  circumstances stirred milling is significantly more efficient than ball milling. As a case in point, the VERTIMILL® grinding mill has been cited in a couple of papers (Nesset et al., 2006; Mazzinghy et al., 2012) as being some 35% to 40% more efficient than ball mills for fine

  Optimization of mill performance by using online ball and pulp measurements Soon after a stop, a mill is a dangerous place to enter for the personnel tasked with taking measurements or samples. Crash stops are difficult to handle. The mill and all feed streams should be stopped simultaneously but, often, they are stopped around about the same time.

  Analysis of Power Draw in Ball Mills by the

  · Abstract Ball mills, like other comminution devices, consume large amounts of energy. Mill operators often have to assess the power draft of mills for an entirely different set of operating conditions or for a reconfigured circuit. It is shown that the power draft can be accurately predicted from analysis of the motion of the charge.
