The attrition grinding action, vertical arrangement, and the finer media size distribution contribute to make stirred mills more energy efficient grinding machines. The Vertimill energy savings range from 30% to greater than 50% compared with traditional ball mills and the SMD energy savings are far greater than 50% of ball mill energy in fine ...Maintaining your Vertimill®. Vertimills offer a range of benefits over traditional ball mills including higher energy efficiency, lower media consumption, reduced maintenance, longer wear life and a smaller footprint. However, Vertimills run into their own challenges in the field in terms of managing wear life as well as maintenance and parts ...

Vertimill® is a unique product offered exclusively by Outotec. Grinding efficiency, reduced media consumption, lower installation cost, minimal maintenance, and minimal liner wear make Vertimill® the lowest total cost of ownership in many applications, substantially improving …The Vertimill has been widely accepted as an energy efficient alternative for grinding applications, also as an alternative to lower the consumption of grinding media. Figure 1 shows a cut away of the Vertimill and its components.

Vertimill provides the lowest total cost of ownership compared to other grinding mills in many applications thanks to its high energy efficiency, reduced media consumption, low installation cost as well as minimal liner wear and maintenance.GRINDING MEDIA WEAR AND ENERGY TRANSFER Cost and performance are the primary considerations when selecting grinding media. Almost half of the operating costs of the SMD® mills at Century is the cost of grinding media (Burgess et al, 2001). Properties that affect the choice of grinding media include: - Size - Type - Competency - Hardness

Vertimill® is a unique product offered exclusively by Outotec. Grinding efficiency, reduced media consumption, lower installation cost, minimal maintenance, and minimal liner wear make Vertimill® the lowest total cost of ownership in many applications, substantially improving the profitability of concentrators.– The Vertimill can be overloaded when… • There is too high of a insoluble loading, and/or • Larger PSD of the insoluble, or • Inadequate loading of grinding media in the Vertimill – …reducing grinding effectiveness and ultimately spilling over the top of the Vertimill When the Vertimill is down 60% of total production is lost

Figure 2 – Vertimill grinding and classification zones . Vertimills can be either top fed (the new feed is introduced into the top of the mill via a feed pipe that deposits the feed just above the grinding media), or bottom fed. In the case of Minas Rio, the cyclone underflow is fed …This paper presents the Vertimill™ pilot grinding tests with a sample of copper ore carried out in closed circuit with a high frequency screen. The sample was crushed to <6 mm.

Vertimill in Secondary Grinding • Semi -Parallel with ball mill because cyclone under flow is split 7 ways • Vertimill stream is pre screen at screen with 6 mm apertures: Oversize ~(10%) sent to ball mill, under size (~90%) sent to Vertimill • Grinding duty – F80 –600 µm …grinding circuit (AG mill), the installation of a Vertimill for secondary grinding duty, and the introduction of hydrocyclones in both the primary and secondary grinding circuits.
