An ounce of prevention – the benefits of frequent inspections. Ideally, Vertimill ® operators should initiate a regular maintenance routine early in the mill's operating life. New operators are recommended to open the mill after 90 days of operation to perform screw liner wear inspection and inspect the mill afterward according to wear …
In this context, a study was initiated to assess not only the performance of a Vertimill grinding circuit. processing a copper concentrate to particle sizes below 80 % passing 25 µm but also to provide Taseko's New. Prosperity project specific design information for grinding to a particle size of 80% passing 17 µm.
The Vertimill stirred grinding mill technology is globally recognised as a leading solution for energy-efficient grinding. Compared to traditional technology, operators can typically save up to 30-35% of the electrical energy and grinding media consumption. A small footprint and easy installation are also big advantages.".

Figure 2: Vertimill Applications . 1.2 Existing Vertimill Applications in Coarse Applications . Table 1 shows a summary of Vertimill applications on primary grinding circuits as secondary and tertiary grinding stage of metallic ores.
Minas-Rio is an Anglo American property, located in Brazil, which started its operation at the end of 2014. The Minas-Rio regrind circuit is currently the largest Vertimill™ installation in the world with sixteen VTM-1500s installed in closed circuit with hydrocyclones.The grinding efficiency of this circuit was verified through a sampling …
The Vertimill™ is a well-known and validated technology in the mining industry and its application in operations is growing due to …
The Vertimill™ efficiency factor could be back-calculate from pilot or industrial circuits using commercial software, but this procedure was avoided because the main idea of the methodology presented in this investigation is perform the vertical stirred mill scale-up from laboratory tests. The factor of 1.35 is derived off standard vendor ...
The 1500 HP Vertimill was operated with larger mean residence times, with a range of 3.2–3.3 min and 4.8–5.0 min in August and October, respectively. An increase of residence time in the 1500 HP Vertimill was observed in October, whereas the residence time of the 1000 HP Vertimill decreased slightly. The comparison of the liquid and solid ...
Vertimill®. Long-lasting wear life with Orebed™ The inside and the door of your Vertimill® are protected by Orebed™ linings. Orebed™ consists of a series of powerful magnets embedded in rubber. The ferromagnetic material in the mill load forms a layer that protects the lining. Installing Orebed™ is fast and easy since no bolts are needed,
