vertical stirred ball mill:

A study of comminution in a vertical stirred ball mill.

The stirred ball mill has been found to be more energy efficient than the tumbling ball mill. An energy reduction of 50% was possible for a product size of 6 microns when the stirred ball mill was employed instead of the tumbling ball mill.

Vertical Stirred Ball Mills — Хонинговальные головки

The advantages of vertical stirred mills are that balls do not have to be elevated and that ball-to-ball and ball-to-wall collisions are much more rapid than in tumbling mills. Attrition is the important breakage mechanism in stirred mills, whereas impact is signifi­cant in tumbling mills.

The liberation effect of magnetite fine ground by vertical

7/1/2012· The vertical stirred mill was a laboratory pin stirred mill. A six-pin stirrer was attached to the gearbox and had a variable speed. The grinding chamber of approximately 9 L was fitted on the gearbox shaft. 11 kg 4–6 mm steel balls were used as grinding media.

4/26/2010· The aim of this study was to investigate the grindability of solid fossil fuels from a thermal power plant by using a vertical stirred mill and conventional ball mill. The solid fossil fuel sample was obtained from the Zonguldak Catalagzi thermal power plant in Turkey. The sample below 3350 μm ( d80 = 2100 μm) was ground in the laboratory scale

seen, the vertical mill consistently presented lower net specific energy consumption than the ball mills which operate on the same circuit. The averages were 11.3, 11.7 and 6.5 kWh/t respectively for ball mill 01, ball mill 02 and vertical mill. Figure 5 Net specific energy consumption of regrinding circuit.

Comparison of energy efficiency between ball mills and

6/1/2009· The work using a vertical shaft stirred mill compared with Bond ball mill, both operated in closed circuit with a classifier, demonstrated a clear trend that on average 30% energy saving can be expected by using the stirred mill to replace ball mill for coarse grinding from a top particle size 3.35 mm to P 80 less than 100 μm.

A study of comminution in a vertical stirred ball mill.

The energy input per ton of grinding media in the stirred ball mill could be 10 times higher than for the tumbling ball mill. Although during coarse grinds the media wear was higher in the stirred ball mill than in the tumbling mill, it became less so as grinding proceeded and for a product median size of 4.8 microns it was the same.

Scale-up and operations of a vertical stirred mill UBC

Stirred media mills are relatively new to mining industry, and several new technologies have been developed such as the VXPmill (vertical stirred mill). There is little technical understanding of optimizing and scaling-up of the VXPmill. This thesis addresses both of these issues and therefore supports commercial applications of this vertical stirred mill. Stirred media mills are influenced by

4/26/2010· The sample below 3350 μm (d 80 = 2100 μm) was ground in the laboratory scale stirred mill and ball mill. The d 80 sizes of the products at the end of grinding periods of 0.25, 0.50, 1 and 4 min in the stirred mill were determined as 190, 102, 78 and 28 μm, respectively. For this purpose, the stirred mill was used at a stirring speed of 360
