[] studied the effect of the impeller design on the media motion inside a vertical stirred mill by using Positron Emission Particle Tracking (PEPT).Three impellers were tested: a flat blade, a pin type and down pitched impeller. This work highlighted how the impeller strongly influences the upper and lower recirculation loops inside the mill, and consequently, the packing

A study of fine particel grinding in vertically stirred

 · stirred media mills. Calcium carbonate was chosen as the feed material. The experiments were firstly conducted in a laboratory scale vertically stirred media mill under various grinding conditions. The operating variables including specific energy, rotational speed,Measurement of the motion of grinding media in a · The mill used for the testwork was supplied by Imerys. As shown in Fig. 1, it is a laboratory scale mill with a grinding pot volume of 2 l.A central pin type impeller with two sets of 90° offset pins driven by a single phase motor stirred the charge.VXPmill for fine & ultra fine grindingThe VXPmill is a vertically oriented stirred media mill that is open to the atmosphere. They are designed with a modular impeller that has removable discs and spacers. Slurry enters at the bottom, travels upward through the mill chamber, and overflows through a media .Stirred Milling Technology – A New Concept in Fine . · STIRRED MILLING TECHNOLOGY Mill structure The vertical stirred media grinding mill uses a grinding chamber filled with small beads whereby comminution takes place by attrition between the beads. The stirring effect is caused by rotating discs mounted on a shaft. There are also stationary discs on the mill body positioned in between eachAnalysis of energy requirements in stirred media millsVertically stirred media mills represent an important tool for the comminution of a range of industrial minerals. In this work, calcium carbonate is ground to size ranges below 2 μm in an Imerys stirred media mill. The role of grinding media on the efficiency is considered, and with the use of a novel, rod shaped grinding media, significant energy savings in ultrafine wet grinding are seen.vertical stirred media mills · vertical stirred media mills.
