In low speed vertical stirred mills, gravity may be considered one of the components of forces acting to produce the abrasive stresses. This has less of an effect in tower mills compared with pin stirred mills due to the lifting effect of the screw flights in the tower mill.
Agitator speed, grinding media size, and feed size were varied in the vertical stirred mill to evaluate their effect on the breakage parameters. Each grinding parameter was individually analyzed, while the others were held constant. Therefore, for each single-size fraction of feed, a total of twelve tests were conducted. After each test, the product was unloaded from the vertical mill

External classification is not needed for the mill product because the mill speed can be adjusted to control the product size. The product particle size distribution is narrow due to the vertical mill design coupled with the internal classification effect of the discs. If the incoming feed from the upstream process is diluted or already
Stirred Mills have been proven to provide energy savings compared with traditional ball mills. The finer the product required, the more efficient stirred mills will be than a ball mill. The attrition grinding action, vertical arrangement, and the finer media size distribution contribute to make stirred mills more energy efficient grinding
The 80% passing target product size of 38 μm was obtained with double helical screw agitator in 20 min of grinding with an expend of 10.53 kWh/t specific energy, whereas, the target product size of 38 μm was achieved with the pin type stirrer at the rate of 21.73 kWh/t. It is evident that grinding in a vertical stirred mill with a double
Stirred media mills have proved to be more energy-efficient than the conventional ball milling for fine grinding applications. The mill performance is governed by a number of operating variables including mill stirrer speed, feed particle size, solids content and slurry rheology. A study was conducted to assess effects of mill speed, media size

Stirred Media Detritor (SMD) is a fluidized, vertical stirred mill designed for optimum grinding efficiency for fine and ultrafine grinding products. SMD’s feed size is typically 80% passing 100 µm and finer, but it can also handle coarser materials in various applications. SMDs have the capacity to operate continuously at full load power
2001-03-01· Abstract. The comminution of limestone and fused corundum in stirred media mills has been investigated regarding specific energy requirement. The experimental results show that the tip speed of stirrer discs as well as the density and the size of grinding media affect the specific energy required to achieve a certain product fineness.
The results suggest that the stirrer speed, media size and slurry density affect the specific energy consumption required to achieve the given product size. Media stress intensity analysis developed for high-speed horizontal mills was modified to include the effect of gravitational force in the vertical stirred mills such as the Tower and SAM
Alternatively, particle size distribution is measured by the Outotec® PSI® on-line particle analyzer and the shaft speed adjusted to maintain constant product size. A compact, simple installation and process. HIGmill has a less complex and more compact process layout and flow sheet than other stirred media mills. The process comprises just a

However, while most studies investigated the effects of such parameters on the fineness of milling products, the relationship between them and the size dispersion of milling products has not been elucidated yet. In this study, we investigated the influence that the direction of the agitator shaft has on grinding performance in a media stirring
The stirred ball mills were operated in batch and continuous mode. The median size of the products from the batch stirred ball mill experiments closely matched those of the continuous grinding experiments under similar grinding conditions. Using a salt solution as a tracer material, an attempt was made to estimate the residence time
and what product size (P80) can be achieved based on various feed, process and mill conditions like specific grinding energy (SGE), bead size and mixer speed. (Kwade 1999). A second subject is the power draw a given sized mill can achieve, i.e. for scale-up and mill sizing from pilot mill data.

Also, the uprising velocity in the mill can be controlled by a recycle pump to affect the product size distribution, prevent over grinding, and reduce the circulating load from the cyclone. Final product size is a factor of applied grinding power, flow rate, and slurry density. The effective operation of the Vertimill® requires these

In the turbulent regime, a 10% increase in impeller diameter increases the power required by more than 60%; a 10% increase in stirrer speed rasies the power
