Effect of stirrer speed on grinding performance in a horizontal stirred mill Abstract As the stirrer speed directly affects the motion of grinding media, and hence the interactions with material particles to be ground, the rotation speed of a stirred mill is well recognised as one of the most important factors affecting the grinding performance.

where SI g is the stress intensity (gravitational), g the gravitational acceleration, and h is the media bed depth. For vertical stirred mills such as the SMD and tower mill, both SI s and SI g are non-zero. For horizontal stirred mills such as the Isamill, net gravitational SI is zero due to symmetry along the horizontal axis.

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 units. The results suggest that this approach can be successfully applied for both mill types. For a given specific energy input, an optimum stress intensiO ...

The results indicate that higher tip speeds give a better performance for horizontal stirred mills if coarse grinding media are used, but energy efficiency actually decreases for tower or semi-autogenous mills when the tip speed of stirrers is increased. Similar findings were also obtained from vertical pin mills (Mankosa et al., 1989).

Chapter 6 Wet Grinding in Stirred Media Mills - … As stirred media mills are operated usually wet, the chapter focuses on wet grinding. Grinding and dispersing in stirred media mills is a process, which is widely used in different industries such as chemical, ceramic, pharmaceutical, filler, ink and cosmetic industry.

Unlike tumbling mills, where comminution occurs from both impact and attrition grinding, in stirred media mills the particles suffer almost entirely attrition breakage between the beads. (Napier-Munn et al., 2005). In stirred mills there are no free-falling possibilities for grinding media, meaning that impact action does not occur.

2.1 Media stirred mill In this study, two types of stirred mills were used: one with vertical agitation shaft and six agitator arms, namely vertical stirred mill, and one with horizontal agitation shaft four agitator arms, namely horizontal stirred mill. The shaft of the vertical stirred mill was a cylinder whose diameter

The cause of hydraulic packing in a mill is related to various factors: viscosity, tip speed, media density and size, and the flow velocity. Flow velocity in a pipe is calcuated by dividing the volumetric flow by the open area of the pipe, i.e., cubic millimeters per second flow divided by the square millimeters open surface area of the pipe.
