Stirred Milling Technology – A New Concept in Fine Grinding

Fig. 1 - Vertical stirred media mill (Outotec, 2012) Principle of operation The mill feed is pumped to the grinding chamber via the feed inlet at the bottom of the mill. During continuous operation, the slurry flow transfers upwards and passes through the rotatingGet price

Energy Use of Fine Grinding in Mineral Processing

18/12/2013Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of a mill's energy budget. Overall Get price

How to resolve the most common hydrocyclone problems

The grinding mill might be the issue Of course, the hydrocyclone isn't the only place to look when you are reviewing the classification of your grinding mill circuit. Often when we're investigating a mill circuit, there are cases where the amount of new feed to the plant has exceeded the ability of the mill to grind the ore fine enough to allow the cyclones to generate Get price

Effect of Grinding Operation on Product Morphology in

Mill operation, particularly mill speed, dictates the dynamics in the mill. Stirred mills are known to break the particles via abrasion under standard operation. However, if the dynamics of the grinding media in the mill are changed, the particles could be more exposed to impact and compression loading that would lead to a different mode of breakage.Get price

Mill maintenance, it's all in the planning

With the grinding mill critical to a plant's throughput, it pays to ensure it receives the necessary care and maintenance. Too often mill maintenance is reactive, occurring due to a breakdown, costing more in repairs as resources are rushed to site, and causing unnecessary stress to site maintenance staff as they battle to get the mill operational again.
