After commissioning the Vertimill in April 2015, grind size reduced significantly in May. Where grind size is reduced by additional comminution equipment, it is useful to calculate overall comminution circuit operating work index (WIo), to determine if its position on the CEEC Bond Intensity curve has changed. Table 1 shows changes in specific energy and WIo assuming the grinding mills were ...

A wide range of grinding media types are used in stirred mills, however in the minerals industry the decision is usually driven by cost which has led to the use of coarse sand, granulated slag and sized ore. A common problem with low grade sand media is that it has internal flaws and tends to break rapidly.

Figure 2 – Vertimill grinding and classifiion 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. The feed is therefore first forced through the grinding zone ...

coarse grinding appliions using the mine vertimill. Energy Use of Fine Grinding in Mineral Processing SpringerLink Dec 18, Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation siz.
For typical fine grinding minerals processing appliions (feed size about 30 to 50 microns and product size 7 to15 microns), it is estimated that only 10 to 15 % of the mill volume has stress energies higher than the Nm required for active grinding. At coarser feed and product sizes, the required stress energy increases and the active volume decreases. In 1997, Jankovic and Morell ...
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 arrangement, the ball mill and Vertimill can ...

· Coarse Grinding Appliions Using The Vertimill, Coarse grinding appliions using the vertimillvertimill 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 minevik has recently developed a Coarse Grinding Appliions Using. 82%.
Using these coarse grinding techniques for finer regrinding underestimates energy requirement because of the different ball sizes, different trajectories and different ball–particle and ballshell interactions in small mills. Modified Bond tests such as the Levin test are more accurate but are often regarded to be too time consumingand requiring too much sample. As a result, regrind mill ...
