Vertimill® is an energy efficient grinding machine. They tend to grind more efficiently than, for example, ball mills with feeds as coarse as 6 mm to products finer than 20 microns. This provides up to a 40% higher energy efficiency . With the Vertimill® simple and robust design, limited liner replacement is required.

Sabo's offering covers grinding media for SAG, ball mill and Vertimill(TM )grinding applications as well as bars for rod mills. These are available in different diameters and materials to guarantee the best performance for the mineral to be processed. Founded in 1841, Santa Ana de Bolueta SA (Sabo) is a privately owned grinding media supplier.

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 by gravity into the bottom of the Vertimills.

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 – P80 –150 µm – 200 mtph • Unfortunately, due to circuit
